Overview

Major Hurricane Ida made landfall on the Louisiana coast on August 29, 2021. After producing devastating damage in parts of Louisiana, the storm weakened as it moved inland over the following two days. By the night of August 31, what was then Tropical Depression Ida moved into the southwest portion of the Appalachians. As it continued northeast through the Appalachians, Ida began to interact with a frontal system, and became a post-tropical cyclone early on September 1. However, the baroclinic influence caused by its interaction with the front caused the post-tropical cyclone to re-strengthen, and it became a strongly forced frontal low as it continued further northeast. From the early morning through the late evening of September 1, the center of the low tracked from over West Virginia to approximately along the Interstate 95 corridor from northeast Maryland to northeast New Jersey.  

Along its path, the remnants of Ida produced severe impacts over a large swath of the eastern mid-Atlantic, becoming one of the area’s worst natural disasters ever observed. Hours of torrential rainfall near and just west of the center's track, fed by remnant tropical moisture, led to catastrophic flash flooding over portions of eastern Pennsylvania and central and northern New Jersey. Numerous rivers experienced major flooding with some having their highest crests on record. In addition, as the system’s warm front lifted through the region, an unusually favorable environment for severe weather developed across much of New Jersey and southeast Pennsylvania. Several tornadoes occurred during the afternoon and evening of September 1, including particularly strong and damaging tornadoes over Gloucester County, New Jersey and Montgomery County, Pennsylvania. The remnants of Ida departed the region by the night of September 1, but flood waters would take several days to recede in some cases, and for some areas, recovery from the catastrophic flooding and tornadoes will take years. Prelminary statistics show that 22 people in our local area tragically lost their lives from the storm, in addition to dozens of others in surrounding areas and the Gulf Coast states. Economic damages, while too early to determine, will likely range well into the billons of dollars.

This page provides a summary of the meteorological evolution and impacts of the remnants of Ida in the NWS Mount Holly forecast area. Information should be considered preliminary, and additional information may be added as it is warranted and as further analysis is conducted.

Observed Soundings

Environment Environment Environment
Figure 19: 12z Sterling, VA sounding. Already, impressive wind shear values are apparent, and instability would soon increase with daytime heating. Figure 20: 12z Wallops Island, VA sounding. Considerable amounts of dry air are seen in the profile, but this would soon be eroded as the remnants of Ida approached. Figure 21: 16z Sterling, VA special sounding. A highly favorable environment for tornadoes is now present with extreme values of low level wind shear/SRH in the presence of increasing instability.
Environment Environment Environment
Figure 22: 00z Sterling, VA sounding. A shift to northwest winds at the surface shows the cold front had moved through by this time, bringing an end to the severe weather threat in that area. Figure 23: 00z Wallops Island, VA sounding. Here, the cold front is yet to move through and the environment remains quite favorable for heavy rain and tornadoes, though wind shear values weren't quite as high as in areas furhter north. Figure 24: 00z Long Island, NY sounding. Extreme wind shear values signified a shift of the severe weather threat to areas further northeast, though lower instability would keep severe weather more limited over Long Island and southern New England.

...SEPTEMBER 1 2021 TORNADOES...

The National Weather Service office in Mount Holly, NJ has 
conducted several storm surveys for damage from storms on 
Wednesday, September 1 associated with the remnants of Ida.

The storm survey information will also be available on our
website at http://www.weather.gov/phi


.Harrisonville-Mullica Hill-Deptford, NJ Tornado...

End Lat/Lon:            39.82/-75.11

The tornado touched down near Harrisonville, NJ doing mostly 
damage to trees and limbs before strengthening and moving 
northeast. As it moved to the northeast, it crossed into the Cedar
Grove area producing more significant damage to trees with many 
trees uprooted. 

The tornado moved into the Willow Oaks subdivision strengthening 
further and producing significant damage to trees, as well as 
serious structural damage to a number of homes. Several homes had 
exterior walls completely collapsed, a number of homes lost roofs 
and upper story walls, and one home had only a few interior walls 
remaining. Vehicles were tossed around and moved, and damage from 
flying debris was observed in several spots.

The tornado continued to move to the northeast to Bridgeton Pike 
where multiple trees had trunks snapped and most of the barns and 
storage buildings at a large commercial farm were completely 
destroyed. The tornado also reached its maximum width at this 
location and was estimated to be around 400 yards wide.

The tornado then continued northeast through the woods with 
multiple trees snapped before entering the subdivision at 
Salvatore Drive. Here the tornado's most significant damage was 
observed with one home completely destroyed with no interior or 
exterior walls standing. Other homes in the subdivision had 
exterior walls collapsed along with garage collapses and vehicles 
being tossed around by the tornadic winds. The consistency of the 
damage along the path of the tornado in this area was EF-3 in the 
middle of the circulation, with EF-2 along the edge of the 
circulation. In addition, the tree damage was not as extensive 
behind the completely destroyed house. Based on the consistency of
the damage along Salvatore Drive, a rating of EF-3 (150 mph) was 
determined.

The tornado continued to the northeast damaging trees and 
structures along its path before reaching a large commercial dairy
farm where extensive damage occurred. Barns were destroyed and 
two large grain silos were toppled. The tornado then crossed 
Jefferson Road and crossed Eachus Road snapping multiple trees. 
Thereafter, the tornado moved into the Breakneck Road area 
producing complete deforestation with nearly 100 percent of the 
trees in a thickly wooded area snapped. 

The tornado path crossed Main St, just south of Chestnut Branch 
Park in Mantua Township snapping and uprooting a number of trees 
before reaching the Delaware Valley Florist commercial greenhouse 
mostly destroying the structure. The tornado damage path then 
continued to the northeast reaching Wenonah, snapping and 
uprooting a number of trees, a few homes lost roofs and one 
structure collapsed. In eastern portions of Woodbury Heights, 
several trees were snapped along a path from Chesnut Avenue to the
intersection of Walnut Avenue and Tanyard Road. Along this path 
on Glenwood Court, two homes lost a significant amount of siding 
on one side and a fence was blown over. 

Less severe tree damage persisted to the northeast along the 
tornado's path toward Deptford where the tornado lifted. 

The National Weather Service in Mount Holly would also like to 
thank local enforcement and emergency management for their 
assistance in the storm survey.


.East Nottingham Township-Oxford, PA Tornado...

An embedded supercell in a quasi-linear feature produced a 
tornado near Oxford, PA. A path of damage began in crop land near 
the intersection of 5th Street and Waterway Road. Tree damage 
continued northeast of here. 

Significant damage occurred in the Wiltshire Development. On 
Slate Hill Drive, one house lost a southeast facing exterior wall.
Another house lost a significant amount of siding and a portion 
of the roof. Tree damage continued in a northeast path. At Hickory
Hill Road, there was damage to the roof of a commercial 
outbuilding and a recreational trailer was flipped on its side.

Sporadic tree and crop damage was noted from drone footage (this 
portion of the path was inaccessible by vehicle) continuing to the
northeast. A metal storage building at a business along Reedville
Road had wall and roof damage. Further northeast there was damage
to turkey pens near the intersection of Baltimore Pike and West 
Branch Road.

Additional tree and power pole damage continued in a northeast 
path. The last damage noted along this continuous path was 
exterior wall damage to a farm outbuilding and crop damage along 
Street Road near Route 10. Sporadic tree damage was observed near 
Route 10 and Ewing Road, but this does not appear to be in a 
continuous path from the other damage, so this may have been 
caused by straight line winds.

The National Weather Service would like to thank Mr. Lou Ruh for 
his assistance with this survey.


.Fort Washington-Upper Dublin-Horsham, PA Tornado...

A semi-discrete supercell thunderstorm began to exhibit rotation 
over Delaware County, PA around 5:15 PM on September 1. The 
rotation continued north-northeast into Montgomery County, and 
eventually strengthened enough to produce a tornado. Minor tree 
damage was first observed along Stenton Ave in Fort Washington in 
the area of the Philadelphia Cricket Club. A path of tree damage 
was observed heading northeast along Joshua Rd and through Fort 
Washington State Park. Some minor shingle and siding damage to 
houses was also seen. 

Damage became more severe after the tornado crossed the 
Pennsylvania Turnpike. At this time the tornado also moved into a 
more residential area. Damage was observed along Montgomery Ave, 
Spring Ave, and Prospect Ave and numerous crossing streets of 
those. This mainly consisted of numerous snapped and uprooted 
trees with minor to moderate roofing and siding damage to a number
of homes. The worst damage was observed slightly farther 
northeast in the area of Stuart Creek in Upper Dublin. A number of
homes suffered partial to near total loss of roofing with many 
damaged to the point of being uninhabitable. At least one home 
experienced partial collapse of exterior walls consistent with EF2
tornado damage. Nearly all trees were snapped or heavily damaged 
in this area as well. 

Damage continued along Route 309 to the area of Upper Dublin High
School. The high school itself suffered roofing damage, and 
significant roofing loss occurred to an Upper Dublin Township 
building adjacent to the high school. A number of residences along
Loch Alsh Ave and several surrounding streets were also damaged. 
A woman was killed when a tree fell on her home on Kenyon Dr, the 
only known tornado-related fatality from this tornado or any 
tornado during this regional outbreak.

Further northeast, damage occurred on and around the Temple 
University Ambler Campus, again consisting of considerable tree 
damage and partial roofing loss on a number of homes and 
university buildings. The tornado then moved into Maple Glen, 
crossing a heavily developed area near Norristown Rd at Limekiln 
Pike. Snapped trees and mostly minor roofing and siding damage to 
several commercial buildings was observed in this area. The 
tornado remained continuous but did begin to lose some intensity 
as it moved into Horsham Twp, traveling east of Limekiln Pike. A 
number of trees were snapped along Babylon Rd. Near Horsham Rd, 
roofing damage occurred to a veterinary hospital, along with 
additional large trees snapped. Damage appeared to end not long 
after that point. The tornado crossed Horsham Rd, but little to no
damage was observed in a couple of parks across the road, 
approaching the Bucks County line. The tornado is believed to have
lifted in that area.

The National Weather Service in Mount Holly would like to thank 
the Montgomery County Department of Public Safety and the Upper 
Dublin Township Police and Fire Departments for their assistance 
in this survey.

The storm which produced a strong tornado in Montgomery County, 
PA, cycled and produced another tornado in Bucks County, PA. 
Damage began near in the area of Neshaminy Creek between Valley Rd
and Pebble Hill Rd in Doylestown. The tornado tracked north- 
northeast from there, producing a consistent path of damage. 
Damage was mainly confined to trees and was fairly extensive at 
times, with much of the path length being heavily wooded. Numerous
hardwood and softwood trees were snapped and uprooted along the 
path. Damage was strongly suggestive of tornadic winds, and a 
tornado debris signature was also evident on radar. The heaviest 
damage occurred near and along a stretch of Edison- Furlong Rd. 
Extensive tree damage occurred along that road and a number of its
cross streets. Several utility poles were snapped in this area. 
Tree damage along nearby Swamp Rd was also significant. The 
tornado continued but began to lose intensity as it approached 
Route 202, with sporadic tree damage observed on Mill Rd. Gradual 
weakening continued and the tornado appeared to lift entirely in 
the area of Burnt House Hill Rd. The extent of tree damage 
suggested maximum winds of around 100 mph. No injuries were 
reported as a result of this tornado.

A tornado embedded within a squall line developed several miles 
southeast of the storm which produced a tornado in Buckingham 
Township. Tornadic damage was first observed in the vicinity of 
Stoneybrook Rd at Eagle Rd, near Jericho Creek. The tornado 
tracked northeastward from there. It passed over the Jericho 
National Golf Club, and sporadic tree damage mainly consisting of 
uproots and large limbs snapped was observed in a path throughout 
the golf course. It then moved over the adjacent Brownsburg Park, 
where additional tree damage was observed and several soccer goals
were observed flipped in various directions. The tornado then 
began to approach the Delaware River. Some minor tree damage was 
observed along River Rd. However, the tornado appeared to lift 
just slightly before reaching the Delaware River, with no apparent
damage on Pebbletown Rd just prior to the river. Throughout its 
path, the tree damage produced by this tornado was fairly 
sporadic, and it may have been discontinuous. Noticeable wind 
damage was also observed for at least a mile east of the tornado 
track, especially near its endpoint close to the Delaware River. 
This is believed to be straight line wind damage, which is 
corroborated by radar data, occurring around the rear flank 
downdraft region of the tornadic circulation. However, the exact 
length and width of the tornadic circulation is somewhat uncertain
due to the surrounding areas of straight line wind damage.

After cycling from an earlier tornado near Mullica Hill, NJ, a 
supercell thunderstorm produced an additional tornado in 
Burlington Township, NJ near the township line with Edgewater 
Park, NJ. Some evidence of RFD winds was prevalent southward 
through the Capitol Hill neighborhood of Edgewater Park with one 
pine tree being uprooted and several small branches being brought 
down all the way south to Pennington Park in Delanco Township, 
NJ,but damage was too sparse to be noted as tornadic. As the 
tornado touched down, numerous hard and softwood trees were 
uprooted along Jennifer Lane in a neighborhood just off of Beverly
Road in Burlington Township. A large branch was also brought down
on a vehicle at the intersection of Jennifer Lane and Squire Way.
Nearby, a pine tree was brought down, breaking a window to a 
residence further west on Jennifer Lane with a small Sycamore tree
also being snapped at the base a few houses down the road. 

As the tornado crossed Shive Place and Handler Drive, several 
trees were snapped and large branches brought down. Soffit damage 
was also observed to a couple of homes nearby. Perhaps the most 
impressive damage was observed along Beverly Road near the 
intersection with Handler Drive where resident noted that nearly 
thirty trees were either uprooted or snapped. Observations seemed 
to agree with that statement with crews working to repair downed 
power lines as well.

The tornado then proceeded towards the Delaware River as it took 
a slight turn towards the north. With only a steel and power plant
lying beneath it-these two structurally sound facilities did not 
appear to sustain any visible damage despite a rather impressive 
viral Tweet with a video of the tornado passing across the 
Burlington-Bristol Bridge. Driving across the bridge for this very
survey, no damage was noted given the structural integrity of the
feature. Several soft wood trees were snapped near Maple Beach 
Road. The end point appears to be near Mill Street, where part of 
a roof covering was peeled off of a comercial building.

A tornado touched down along Emmons Drive along Route 1 in 
Princeton, NJ as a remnant supercell moved northward after 
producing the Mullica Hill and Burlington, NJ tornadoes earlier 
Wednesday afternoon as Ida's remnants moved through the region. 
Damage first occurred as several small branches were brought down 
along the Whole Foods and Wendy's parking lots along Route 1 in 
far eastern Princeton Township, with a continued path of minor 
branch damage extending northward along Farber Road, Meadow Drive,
and Canal Pointe Boulevard adjacent to Route 1. Several medium- 
size trees were also uprooted with numerous small branches having 
been brought down along the western periphery of the Marketfair 
shopping parking lot. 

From there, the tornado continued northward with minor tree 
damage having occurred along Carnegie Center Boulevard as the 
tornado moved northward. Several small branches were also brought 
down in a residential area along Heritage Boulevard with one pine 
tree even having been snapped. An additional pine tree was also 
uprooted along Alexander Road near Glenview. The tornado then 
snapped several small hardwood trees, knocking down several 
utility poles and power lines along Washington Road. A tree was 
also uprooted along Lower Harrison Street along Carnegie Lake 
before the tornado lifted somewhere over the lake.

Figure 1: KDIX radar reflectivity factor (left) and storm relative motion (SRM, right) for the 0.5 degree elevation angle valid 2009 UTC to 2025 UTC 1 September 2021. The area’s first tornado of the day, and also the first strong (EF2+) tornado, occurred in southwestern Chester County, PA near Oxford. A line of thunderstorms moved north-northeastward out of Maryland. Elements within this line, which had previously consisted of more discrete cells, already had a history of producing tornadoes over Maryland. As storms crossed into Pennsylvania, they moved towards a warm front in the area. A sharp wind shift along this front likely aided in a restrengthening of low level rotation as storms interacted with it. A velocity couplet can be seen forming in the SRM data soon after storms move into Chester County and continuing for several minutes before dissipating. One challenge with this tornado was its far proximity from the radar. Even at its lowest 0.5 degree elevation angle, the KDIX radar was scanning at an elevation of nearly 8000 feet. While the rotation was clearly evident, the long distance from the radar prevented a more detailed view of the tornadic couplet, which appears broader and less-defined in the SRM data than it probably was in reality. Figure 2: KDIX storm relative motion (SRM, left) and correlation coefficient (CC, right) for the 0.5 degree elevation angle valid 2017 UTC to 2028 UTC 1 September 2021. NWS meteorologists use dual polarization radar data, particularly CC, to confirm tornadoes via radar. Lofted tornadic debris, when detected, produces a distinct pattern of lowered CC values, known as a tornado debris signature (TDS). This is due to the radar detecting non-uniform, non-meteorological targets such as leaves or other tree debris and structural debris, as opposed to normal meteorological targets like raindrops, which produce high CC values. Whether or not a tornado produces a TDS varies by its strength and what type of debris, if any, it is lofting. Another important factor is its distance from the radar. All else being equal, a tornado closer to the radar will more likely be detected via a TDS, since the radar beam is scanning lower and thus the tornado doesn’t have to loft debris as high for a TDS to be seen. Weak tornadoes at long distances from the radar will rarely produce a TDS since they usually do not loft debris high enough. For the Oxford tornado, the KDIX radar beam was scanning quite high at nearly 8,000 feet. Nonetheless, a faint TDS appeared to develop between Oxford and Russellville, indicating tornadic debris being lofted to a height of around 8,000 feet or slightly higher, which is a common value for an EF2 tornado.
Environment Environment
Figure 3: Same as Figure 1 valid from 2123 UTC to 2154 UTC 1 September 2021. The second tornado of the day occurred over Montgomery County, PA. This strong, long-tracked EF2 tornado produced extensive damage along parts of its track, especially in Upper Dublin Twp, PA in the areas of Fort Washington, Ambler, and Maple Glen, and near Horsham. This loop begins a little over 10 minutes before the tornado formed. Broad rotation is present initially in the SRM data, but as the loop progresses, the storm undergoes a very methodic tightening of the rotation, eventually into a tight tornadic couplet near Ambler. The couplet remains well-defined for several minutes before gradually weakening and becoming more broad again. The peak gate-to-gate shear detected by the KDIX radar was 115 kts. The convective structure of this cell was notable, as it had characteristics of both a semi-discrete, high precipitation supercell, as well as of a QLCS. Similar to the Oxford tornado, interaction with a warm front likely contributed to the formation of this tornado. Figure 4: KDIX radar reflectivity factor (top left), storm relative motion (SRM, top right), correlation coefficient (CC, bottom left), and spectrum width (w, bottom right) for the 0.5 degree elevation angle valid 2134 UTC to 2157 UTC 1 September 2021. The Montgomery County tornado produced an especially well-defined TDS. Reduced CC values begin to appear south of Ambler, then become extremely pronounced near Ambler itself as the tornado reaches peak intensity. The size of the TDS, magnitude of the lowered CC values (in the range of 0.4 to 0.6), and the signature’s longevity are all indicators of a strong tornado. Lofted debris can continue to be seen even well after the tornado lifts as lightweight bits of leaves, structures, etc. remain suspended and carried northward by strong southerly winds aloft. Finally, the debris signature can even be seen in the traditional reflectivity data. Near Ambler, enhanced reflectivity values in excess of 60 dBz, denoted by pink colored pixels, begin to appear in concert with the large reduction in CC values. This is caused by strong returns off of a large volume of lofted debris. While the CC data is more reliable and comprehensive, in times prior to dual polarization technology, the presence of this so-called “debris ball” signature was a way to confirm the presence of a likely strong tornado. Because of these signatures in this storm, meteorologists had high confidence a strong tornado was likely in progress even before damage reports could be received.
Environment Environment
Figure 5: KDIX correlation coefficient data for the 0.5 through 5.1 degree elevation angles for the 2148 UTC volume scan 1 September 2021. Another way to roughly estimate tornado intensity is TDS height. Stronger tornadoes usually loft debris higher, allowing the TDS to be visible at higher radar elevation angles. In the case of the Montgomery County tornado, the TDS can continue to be seen as the radar beam tilts higher. The TDS is clearly visible to a height of about 11,000 feet. From there, data becomes noisy due to interference from lowered CC values caused by the freezing level (in other words, the level at which the radar is detecting frozen precipitation changing to rain, which always produces modest CC reductions). However, while it is not definitive, there appears to be indications of debris as high as the 4.0 degree angle, which at that distance from the radar is scanning at about 18,000 feet. A TDS height of 18,000 feet typically corresponds to a strong EF2 or EF3 tornado. Figure 6: Same as Figure 1 valid 2149 UTC to 2208 UTC 1 September 2021. Within the same storm complex that produced the Montgomery County tornado, another area of rotation developed just a few minutes after that tornado lifted. Early in this loop, the late stages of the Montgomery County tornado can be seen southwest of Warrington as that tornado gradually dissipates. However, a second area of rotation can be seen to its east. This initially broad rotation briefly tightens into a well-defined couplet just southeast of Doylestown. While not nearly as strong or long lasting as the Montgomery County couplet, with peak gate-to-gate velocity of 65 kts, this couplet was associated with an EF1 tornado, the third tornado of the day. This tornado was on the ground for only a few minutes, producing mainly tree damage.
Environment Environment
Figure 7: Same as Figure 2 valid from 2202 to 2213 UTC 1 September 2021. The Doylestown area tornado produced a TDS late in its life cycle, which remained evident after the tornado lifted due to lightweight debris lingering in the air. It can be seen forming near the small red marker. Higher elevation data showed the TDS extended to a height of between 6,000 and 7,000 feet. This is a typical value for a mid-grade or higher end EF1 tornado such as this one. Figure 8: The complex of thunderstorms which produced tornadoes in Montgomery County and near Doylestown produced a final tornado in Bucks County about half an hour after the Doylestown tornado dissipated. By this time, these storms very much had a QLCS type structure, but areas of rotation remained within the line. In this loop, an area of broad rotation can be seen tightening into more of a couplet feature a little ways before it reaches the Delaware River at the borders of Pennsylvania and New Jersey. The couplet remains evident for just a couple of radar scans before dissipating as the storm reached the Delaware River. Storm survey results showed this area of rotation produced an EF1 tornado in Upper Makefield Twp, in addition to adjacent areas of straight-line wind damage produced by this QLCS. Damage was mainly confined to trees. Dual polarization data showed no indication of a tornado debris signature (TDS) with this tornado.
Environment Environment
Figure 9: Same as Figure 4, valid 2148 to 2237 UTC 1 September 2021. This loop shows the evolution of the Gloucester County tornado. A small red marker is placed near where the worst damage occurred in Mullica Hill. There are many items of interest in this loop, far too many to discuss in detail here. The evolution of the storm from a fledgling supercell into a mature, tornadic supercell is apparent. Also evident are data quality issues in the SRM data. While the rotation can be seen, the data within the rotation is noisy. The reasons for this are complex but relate to a combination of the structure of the storm and its angle relative to the KDIX radar. The nearby KDOV and TPHL radars had even more significant data quality issues for similar reasons, and are not shown. A debris signature is seen in both conventional reflectivity and the CC data, appearing shortly before the rotation reaches the red marker. It can be seen expanding as the tornado continues northward. In the SRM, CC, and w data, a Three Body Scatter Spike (TBSS) can also be seen near the red marker. This signature is almost always caused by the presence of large hail in a thunderstorm. In this exceptionally rare case, it is actually tornadic debris causing the TBSS. The circulation continues northward, weakening late in the loop as the tornado lifts. However, rotation remained present, and the storm would soon cycle and produce another tornado. Figure 10: Vertical cross-sections of reflectivity (left) and CC (right) for the 2232 UTC volume scan of the KDIX radar on 1 September 2021. The image is taken diagonally across the storm which produced the Gloucester County tornado. The CC data shows the vast vertical depth of the TDS produced by this storm. An analysis of the radar data showed that debris from this tornado was lofted to a height of approximately 25,000 feet. The approximate outline of the TDS is circled in the CC data. A debris signature this deep, which is extremely rare, typically corresponds to a strong EF3 or EF4 tornado. However, the sample size of cases for tornadoes of EF4 intensity or greater is small due to the rarity of their occurrence.
Environment Environment
Figure 11: KDIX correlation coefficient (CC) valid 2219 UTC 1 September 2021 to 0016 UTC 2 September 2021. This two hour loop provides a remarkable, and chilling, look at the journey of debris produced by the Gloucester County tornado. A few frames are annotated with notable features and times. As the loop plays, the TDS can be seen developing over Gloucester County. Debris is then visible being carried northward and fanning out over a much wider area, long after the tornado lifted. The “fan” of debris is easily seen in the CC data as it continues northward. What is being observed is small, lightweight material – bits of leaves, perhaps some small bits of paper or insulation, etc., that an observer from the ground would be unlikely to notice especially at further distances from the source. The signature weakens over central New Jersey before seeming to reinvigorate several miles further north, even though no new debris was being lofted. It is not clear why this occurred, and it cannot be determined conclusively if this was still the same debris, though the placement and behavior of the re-invigorated band of lower CC, as well as data from higher radar elevation angles, suggests it probably was. Transport of debris was especially efficient in this case for a couple of reasons. First there was a large initial volume of debris lofted to an unusually deep vertical extent (see Figure 10). Second, strong low and mid-level southerly winds allowed for a fast transport motion of the debris. Based on this data, it can be concluded that small amounts of debris from near Mullica Hill were carried at least as far as north-central Somerset County, approximately 70 miles north-northeast from the origin of the debris. If the returns late in the loop over Sussex and Morris Counties are in fact the same debris, that would be a distance of around 100 miles. Figure 12: Same as Figure 1 valid 2240 UTC to 2314 UTC 1 September 2021. The Gloucester County tornado lifted around 6:30 PM EDT/2230 UTC, though sporadic wind damage was also reported in parts of Camden County as the storm moved north. As the supercell continued north, it retained strong rotation, and appeared very likely to produce another tornado. This second tornado would begin in Burlington County, New Jersey, a little southwest of the city of Burlington, as a new tornadic couplet formed in a classic example of a cyclic tornadic supercell. This is shown nicely in the SRM data here. Soon after the touchdown of a new tornado was confirmed, NWS Mount Holly issued its first ever Tornado Emergency for areas near Bristol, as it appeared a strong to violent tornado would affect the densely populated area. Thankfully, and for reasons not entirely clear, the tornado quickly weakened and dissipated on the Pennsylvania side of the Delaware River. While observed damage on both the New Jersey and Pennsylvania sides of the Delaware River supported only an EF1 rating, it is distinctly possible, and probably likely, that the tornado was stronger over and along the banks of the river, where radar data suggests it peaked in intensity. Viral photos and videos of the tornado near and over the Delaware River also lend credence to this possibility.
Environment Environment
Figure 13: Same as Figure 4 valid 2253 to 2309 UTC 1 September 2021. The Burlington-Bristol tornado produced a TDS, although it is a rather complicated one to follow in radar data for several reasons. For much of the loop, low CC values associated with lingering debris from the Gloucester County tornado are seen moving northward, and eventually mostly off screen. Some noisy CC values are present south of the storm due to weak power returns in an area of low reflectivity. A couple of features that look very similar to TDS’s appear southwest of Burlington towards the middle of the loop, but further analysis revealed they were caused by other factors. The legitimate TDS appears almost directly over Burlington and tracks over Bristol before beginning to weaken heading northeast after the tornado lifted. Vertical data showed the TDS extended to a height of about 8,000 feet. Figure 14: Same as Figure 1 valid from 2326 UTC to 2338 UTC 1 September 2021. The final tornado of the day occurred in association with what remained of the storm that produced the Gloucester County and Burlington/Bristol tornadoes. The storm mode became more linear and less discrete overall as it continued moving north. Broad rotation remained within the complex, and with a warm front still in the vicinity, rotation continued to make occasional attempts to tighten and produce a tornado. One such strengthening of rotation was seen over Mercer County, New Jersey, near Princeton. In this loop, rotation is broad initially. There are two areas of tightening rotation that become interesting as the loop goes on, one which passes south of Princeton and the other which passes just west of Princeton. Both velocity couplets appear capable of producing a tornado. However, tornadic damage was found only in association with the more southern couplet. A weak, brief EF0 tornado was found to have occurred in West Windsor Twp.
Environment Environment
Figure 15: Same as Figure 2 valid from 2328 UTC to 2339 UTC 1 September 2021. The West Windsor Twp tornado did produce a small but well-defined TDS. As is typical with weaker tornadoes, the TDS was not vertically deep, only extending to around 4,000 feet. However, its fairly close proximity to the radar aided in the TDS detection. Note that no indication of a TDS is seen with the northern velocity couplet despite its seemingly similar intensity on radar. Figure 16: Multi-Radar Multi-Sensor (MRMS) accumulated low level rotation tracks for the 6 hour period ending 0130 UTC 2 September 2021. Additional information on this product can be found here, but ordinary users should be aware this is a complex product. While the data is noisy (inherent to the product), some interesting features are noted. A long track of strong rotation is seen in association with the supercell which produced the Gloucester County, Burlington-Bristol, and West Windsor tornadoes. Rotation associated with the Montgomery County tornado is seen (and in fact is probably the most impressive of all the rotation tracks). Areas of enhanced rotation associated with the two tornadoes in Bucks County area apparent. A rotation track corresponding to the Chester County is seen, but is quite weak, largely owing to that area being far from any radar site, with no high quality low level data available. There are also several other areas of rotation including some fairly strong and long-tracked ones which were not found to produce tornadoes, such as one on the upper Eastern Shore of Maryland. This product is used both during warning operations, as well as after as meteorologists attempt to determine areas where a tornado may have tracked, to aid in storm survey efforts.

Ida's Devastating Floods

 

Foreword

Torrential rainfall produced by the remnants of Ida brought historic flooding to the mid-Atlantic. Rainfall totals across the region varied widely. Southeastern portions of the area were generally spared from excessive rainfall. However, much of eastern and southeastern Pennsylvania and central and northern New Jersey received 5 to 10 inches of rain. For several reasons, including geographic, hydrologic, and societal factors, these areas are the most vulnerable to flooding in our local area. The occurrence of a rainfall event of this magnitude in these areas had devastating consequences. In most cases, nearly all of the rain came within a window of little more than 6 hours. In addition, the summer of 2021 had already been quite wet across much of the region. Multiple impactful flooding events had already occurred, and the region was primed for an even more significant event. The remnants of Ida would prove to be that event. Flooding took on multiple forms. First came the initial wave of flash flooding, when many smaller creeks came well out of their banks and roads became flooded due to overwhelmed drainage systems and the sheer volume of water. The majority of fatalities occurred in this phase of the event, with many of the victims being motorists. However, once the rain ended, the second phase of flooding involved slower responding main stem rivers, which continued to rise. This led to additional flooding of homes and roads into the following day and in some cases several days. For example, the Schuylkill River at Philadelphia did not crest until the morning of September 2, and as it continued to rise, floodwaters inundated portions of the city with the worst flooding of the modern era. Other rivers such as the Millstone and Passaic would also take more time to crest. The main stem Delaware River also experienced flooding, though it thankfully peaked mainly in minor flood territory owing to a lack of significant rainfall farther upstream the river.

In the NWS Mount Holly County Warning Area (CWA), preliminary statistics show that 21 people tragically lost their lives due to flooding related causes, encompassing all but one of the CWA's fatalities during the event. Many homes experienced flooding, some roads were damaged or washed out, and a number of area rivers and creeks experienced major flooding with several seeing their highest crests on record.

A list of observed rainfall totals can be found under the "Rainfall Reports" tab. Numerous hydrographs from area rivers and creeks are provided on another tab on this page. The images and descriptions below provide additional context on the severity of flooding produced by the remnants of Ida.

This massive volume of rainfall over such a short period of time would lead to devastating floods. Figure 2: Same as Figure 1 and with the same scale, but for the 24 hour period ending September 2 at 5:00 AM EDT. This map captures the Ida event in its entirety for the region. Compared to Figure 1, this map shows much more rainfall across the western and southwestern portion of the domain, where the bulk of the rain fell before the time period encompassed by Figure 1, and across the southeastern portion of the domain, where most of the rain fell after the period in Figure 1. However, note the region extending diagonally from about Chester County, PA into northeast NJ. The amounts are quite similar to those in Figure 1, showing that the vast majority of rain from the entire event in those areas fell within the 6 hour block from Figure 1.

Figure 3: 24 hour cumulative rainfall from the Delaware Environmental Observing System (DEOS) for the Ida event beginning at 1:00 PM EDT on September 1 and continuing through the duration of the event. DEOS provides a high quality look at rainfall over Delaware and in Chester County, PA. Rainfall amounts rise rapidly during the late afternoon and evening of September 1, especially across Chester and New Castle Counties. A widespread 6 to 8 inches of rain fell in Chester County, and it became one of the hardest hit counties for flash flooding. Central and southern portions of Delaware were spared significant impacts. Figure 4: Multi-Radar/Multi-Sensor (MRMS) Average Recurrence Interval for the radar-estimated rainfall ending at 0200 UTC 2 September 2021. This image shows the average return period in years for the amount of rain that fell in this 6 hour period, which can be approximated by the rainfall totals from Figure 1. The scale maxes out at a 200 year return period, however, that proved to be severely inadequate for this event. A 200 year return period means that a given event would be expected to occur on average once every 200 years. Ida’s rainfall easily eclipsed that threshold over much of the area seen above. While confidence in return periods begins to decrease at these more extreme thresholds, the actual return period for this amount of 6 hour rainfall for the hardest hit areas was probably closer to 500 or 1000 years.

Figure 5: MRMS CREST Unit Streamflow valid 2220 UTC 1 September 2021. The CREST Unit Streamflow product is used by forecasters to monitor flash flooding potential. The product is inherently noisy, however, values in the orange and red range, when they occur with reasonable spatial continuity, are usually a good baseline for a forecaster to consider issuing a Flash Flood Warning. The presence of widespread red and pink values typically indicate high confidence in flash flooding. When blue pixels begin to appear, especially over a wide area, it is typically an indicator of significant flash flooding. Here, the highest values are over southeastern Pennsylvania, while heavier rain is yet to arrive in areas further northeast. To see such a large area of purple, blue, and white pixels as the scale maxes out is highly unusual and is seen only in the rarest cases. Figure 6: Same as Figure 5 valid 0100 UTC 2 September 2021. The highest streamflow values had now moved into central and northern New Jersey as the heavy rain continued pushing northeast. It is truly exceptional to see this scale maxed out over such a wide area, and a forecaster familiar with the product would have high confidence in significant and potentially catastrophic flash flooding based on this image. While values had begun to ease over southeast Pennsylvania by this time, they remain quite high, a sign that lingering flooding was still ongoing.

Figure 7: Weather Prediction Center (WPC) Day 1 Excessive Rainfall Outlook (ERO) issued 0820 UTC 1 September 2021, valid 1200 UTC 1 September 2021 through 1200 UTC 2 September 2021. The (WPC) issued a forecast for a High Risk of excessive rainfall over a large portion of the eastern mid-Atlantic. This means they were forecasting a greater than 50% chance of rainfall exceeding flash flood guidance within the high risk area. WPC High Risk days are rare and often encompass some of the nation’s deadliest and costliest flash flooding events. When issued, they are associated with expectations for widespread, severe flash flooding and the flooding of areas that do not normally experience flash flooding. Figure 8: Verification of the forecast from Figure 7. The forecast from WPC proved to be prescient. Contoured in solid lines on the map are the WPC risk categories, the same ones that are shaded in Figure 7. Local Storm Reports (LSRs) of flood and flash flood events from local NWS offices are plotted as small squares. Finally, the blue and red shaded areas provide objective analyses of where excessive rainfall actually occurred based on radar/gauge reports versus Flash Flood Guidance (FFG) and Average Recurrence Interval (ARI). The map is noisy due to the huge volume of LSRs issued by local NWS offices, as for example many blue and red shaded areas are impossible to see due to being covered by LSRs. NWS Mount Holly issued 239 flash floods reports alone. However, it clearly shows the worst impacts occurred within the High Risk area, with significant impacts in the Moderate Risk area as well.

Figure 9: Water flooding the station of the Raritan Twp Fire Company in Hunterdon County, NJ. Firefighters, police, and other local first responders heroically rescued hundreds of people across the region as motorists became stranded in their vehicles, in addition to numerous calls for assistance at area homes due to flooding and, in some cases, tornado damage. Figure 10: Flood waters near the junction of Routes 202 and 31 in Hunterdon County. Scenes like this were repeated countless times across portions of eastern Pennsylvania and central and northern New Jersey.
