----- IMPORTANT 2023 UPDATE -----

Significant updates were made to several tornado tracks and wind swaths impacting the NWS Mobile/Pensacola area in the 2018 to 2023 timeframe thanks to the introduction of high-resolution Sentinel, Worldview, and Planet satellite imagery. One or multiple tornado tracks/wind swaths listed on this event webpage were updated in 2023.
 

An updated graphic and details surrounding these significant updates can be found further down on this webpage in the section for that specific tornado track or wind swath. More information on this Local Tornado Reanalysis Project and a list of all updates can be found on our webpage at weather.gov/mob/TornadoReanalysis or the National Damage Viewer.
 

Here is a list of the significant updates:

1. December 14, 2022 - Updated Tornado - Washington/Choctaw County, AL: The overall track of the 1st tornado that occurred west of the Frankville community received cosmetic updates based on Worldview satellite imagery. The EF2 intensity remains the same.

 

2. December 14, 2022 - Updated Tornado - Choctaw County, AL: The starting point of the 2nd tornado that occurred northeast of the Frankville community was extended further to the southeast based on Planet and Worldview satellite imagery. The EF2 intensity remains the same.

...NWS Damage Survey for 12/15/2022 Severe Weather Event
Update 1...

.Summerdale Wind Damage...

National Weather Service meteorologists surveyed damage in
Summerdale, AL and determined it to be from straight line wind
damage. The tin roof of a building along Highway 59 was peeled
off, with the roof decking remaining in place. A tree and some
power lines were downed in the same area. A few miles to the
northeast, near Summerdale School, a few limbs were downed and the
underside of an awning was damaged. Due to the sporadic nature of
the damage it was determined to be from straight line winds of up
to 60 mph.

Special thanks to the Baldwin County EMA and the Summerdale Fire
Department for their assistance with the survey.

More details about damage surveyed in Choctaw County will be
provided in the coming days.

...NWS Damage Survey for 12/14/22 Tornado Event Update #1...

.Update...This serves as an update to the Frankville Tornado from
12/14/22. The major changes with this update were to adjust the
intensity of the Frankville tornado from 115mph to 130mph based on
extensive deforestation noted on sentinel satellite imagery, 
making it a high-end EF2. Additionally, via sentinel satellite 
imagery from this afternoon it has been determined that two 
tornadoes were responsible for the damage across northeastern 
Washington and southeastern Choctaw Counties. Additional details 
can be found below in each tornadoes summary.

Survey Summary:
An EF2 tornado has been confirmed in far northern Washington into
southeastern Choctaw Counties. The tornado touched down as an
EF0 along Dry Creek Road where a few trees were uprooted. The
next available road was along County Road 31 where significant
tree damage occurred to the north of Frankville. Numerous trees
were snapped or uprooted in a 120 yard swath. Significant
snapping and deforestation seemed evident looking further
southwest along the track; however, this area was inaccessible at
the time and required satellite data to confirm the degree of
damage.

Update 12/18/22: Our first sentinel satellite imagery pass
was this afternoon and cleared up the details of how this tornado
evolved. The first major change was to the intensity of the 
tornado. Complete deforestation of trees to the southwest of 
County Road 31 was noted on satellite imagery, indicating numerous
if not all trees in the path were uprooted/snapped low at their 
base. Based on this, the intensity is bumped to 130mph making this
a high-end EF2. The next major change is to end the tornado just 
northeast of County Road 31. Sentinel satellite imagery indicates 
the tornado occluded to the left rather abruptly, and reached its
widest point of 140 yards as it once again produced EF2 damage 
with widespread deforestation during the occlusion process. The 
damage path ends abruptly once the tornado was moving due north on
satellite imagery. It's possible it continued to travel to the 
north for a bit while weakening, however, based on the storm
survey on Blue Dirt Road it never reached the road. This 
satellite imagery explains the discontinuity that was noted in the
original storm survey downstream by Blue Dirt Road where a new 
tornado began.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak......65 to 85 mph
EF1...Weak......86 to 110 mph
EF2...Strong....111 to 135 mph
EF3...Strong....136 to 165 mph
EF4...Violent...166 to 200 mph
EF5...Violent...>200 mph

Survey Summary:
After reviewing sentinel satellite imagery available on 12/18/22,
the determination has been made that the segment of the original
surveyed tornado track from Blue Dirt Road to Highway 84 was a
separate EF2 tornado with peak winds of 115mph. The original
tornado occluded a few minutes prior to the genesis of this
tornado. A remarkable gradient at the point of genesis was noted
by the survey team in a field of snapped/uprooted trees, where 
trees went from untouched to numerous snaps of softwood trees in 
as little as 5 to 10 feet. Based on sentinel satellite imagery, 
the tornado maintained intensity, perhaps slightly strengthening 
as it moved off to the northeast of Blue Dirt Road where 
significant deforestation was noted in an approximate 120 yard 
swath. At the tornadoes halfway point, it likely weakened to an 
EF0/EF1 as it passed by a field with no notable tree damage on 
satellite imagery. Once the tornado reached Highway 84, it was a 
very weak EF0 that uprooted a couple softwood trees, lifting at 
that location.
