Heat Continues in the Northeast and Northwest U.S.; Areas of Flash Flooding In the Ohio Valley and Southwest

Dangerous heat will continue to impact portions of the interior Northwest and Northeast U.S. Some relief is expected by Wednesday for the Northeast. Monsoon showers and thunderstorms may result in flash flooding and debris flows from the Four Corners region into the Great Basin this week. Thunderstorms, some severe, may produce excessive rainfall from the Ohio Valley to the Central Appalachians. Read More >

Survey Summary:


The remnants of Ida produced one of the strongest tornadoes in the past decade of Maryland`s history. Only four other EF2 or stronger tornadoes have occurred in the state in the past 10 years.

On Wednesday afternoon, a tornado that peaked in intensity with winds estimated at 125 mph traveled northeast along a path through Anne Arundel County and the City of Annapolis. It not only snapped numerous trees, but also produced significant structural damage to homes, businesses, and a school. Fortunately, there were no injuries reported, even though it tracked through a heavily populated area. Several eyewitnesses to the event reported getting the NWS Tornado Warning through their cell phone in advance, and sheltering in response to the warning.

From the NWS storm survey, the first damage noted, and recorded touchdown point was in Owensville, Maryland, in southern Anne Arundel County, near the intersection of Sudley Road and Owensville Road. This included a large limb from a tree top over Sudley Road and several portions of large cedar trees snapped along Owensville Road. The tornado moved northeast across rural southern Anne Arundel County before crossing Mill Swamp Road. Here, about a quarter of a mile east of the intersection with Dove Farm Road, dozens of trees and large branches were snapped and uprooted in a path from southwest to northeast as far as you could see in either direction from the road. While the dominant direction of the tree damage was being blown down to the north or northeast, there were trees downed in multiple directions, and many were topped.

The tornado intensified further as it moved into the South River Colony community. Dozens of trees were downed along the easternmost portions of Monarch Drive. Homes near the intersection of Monarch Drive and Red Admiral Court were particularly hard hit by some of the strongest winds of the entire tornado path. Several had significant portions of their roof damaged or removed, and one home in the middle of the track was unroofed entirely. One resident in this area reported seeing the tornado as it approached. The tornado then crossed South River Golf Links before moving into a campus of school buildings that includes South River High School and the Center of Applied Technology South. There it damaged the upper parts of the football field grandstands and concessions stand, damaged the roof, and caused cosmetic damage to some of the upper portions of the Center of Applied Technology South. The schools were left structurally sound, and the staff and some students that were there were able to shelter without injury.

The tornado crossed Central Avenue around 2:11 PM and moved into Edgewater. Here it crossed the communities of Woodland Beach, Londontowne, and Edgewater Park. Dozens of trees and large branches were snapped, and portions of 5 to 10 roofs were noted to have been damaged. One home near the intersection of Millstone Drive and Oakwood Road had only damaged roof trusses remaining of its roof.

The tornado crossed the South River and moved through western portions of the City of Annapolis at peak intensity with winds estimated at 125 mph at 2:20 PM. Several trees were snapped along the path as it crossed Aris T. Allen Boulevard just east of the Annapolis Harbour Center shopping area. It crossed Forest Drive at the intersection of Parole Street. Several homes there sustained roof damage, and one home was unroofed entirely. As it crossed the area near the intersection of West Street and Lee Street, the most substantial structural damage was noted. A large warehouse building had the winds enter the south side of the building and blow out a large portion of the west side cinder block wall. The roof with large metal trusses was largely removed. A fast food restaurant had its sign entirely removed from its post. Another commercial building had its roof removed, significant upper portions of the cinder block building removed, and its large commercial sign post blown over. A strip mall across the street had its windows blown out and flat roof damaged. All the telephone poles and attached wires along this stretch of West Street were downed. Another commercial building had its windows blown out. Several eyewitnesses saw the tornado as it passed.

Additional residential roof damage occurred as the tornado moved north over Bowman Court. From here, the tornado crossed into the community of Admiral Heights. Affected were areas along Halsey Road and adjacent Cedar Park Road. Here, the wind did not directly cause any structural damage, but about a dozen trees were snapped. That included one large, healthy tree about two and a half feet in diameter. The tornado crossed Weems Creek and Rowe Boulevard, and then snapped several trees along Riverview Avenue.

Finally, the tornado crossed US Route 50/301 a few hundred yards west of the Severn River Bridge, snapping trees on both sides of the highway. The final damage noted occurred at the end of Acorn Drive at the last residential property that sits on the shore of the Severn River. Several trees were snapped here. The tornado dissipated here, or as it crossed the Severn River. The survey team was not able to find any damage north of the Severn River, and video evidence from social media indicates the funnel dissipated here.

The National Weather Service Baltimore/Washington thanks the first responders and the Offices of Emergency Management of the City of Annapolis and Anne Arundel County, who all provided invaluable support for this storm survey.

Survey Summary:


A NWS storm survey team determined that aN EF-0 tornado occurred near Edgemere in Baltimore County, Maryland, on Wednesday afternoon, September 1, 2021. This tornado produced scattered minor tree damage across an approximate 6.7 mile path. This tornado was produced by the same supercell that produced the Anne Arundel County/Annapolis tornado roughly a half hour prior.

The first damage noted was near Fort Howard Park where there were broken tree branches and a hardwood tree snapped. As the tornado progressed to the northeast, hardwood and softwood trees were snapped and uprooted along Fort Howard Park Road. The tornado continued its northeast trek through North Point State Park where more broken tree branches and softwood trees were found snapped. Sporadic damage continued throughout the park before the tornado crossed the Black River.

As the tornado moved northeast over Rocky Point, leaf debris and small branches covered Rocky Point Golf Course. The northeast track continued just west of Browns Creek where hardwood trees were sheared on the tree line and tree branches were broken. The last of the damage was found near Holly Beach.

The National Weather Service Baltimore/Washington thanks Baltimore Countys Office of Homeland Security and Emergency Management for their assistance with locating damage.
