Location Date/Time Deaths & Property & Event Type and Details Injuries Crop Dmg One of four confirmed tornadoes spawned by Tropical Storm Isaias over lower southern Maryland touched down along Point Patience Drive between the Navy Recreation Center Solomons Fishing Pier and Third Cove. The tornado tracked northeastward roughly along Patuxent Drive, uprooting and snapping numerous trees along its path. The trees fell in a convergent manner over a path of nearly one mile long and about 175 yards wide, indicating a tornadic circulation was in contact with the ground. Two recreational vehicles on the Navy facility were smashed by falling trees. Fortunately there were no occupants at the time. Trees fell on numerous recreational facilities on the compound, and damage was noted to outdoor umbrellas at the pool which were rated for hurricane force winds. NWS 88D Doppler Radar, as well as the FAA Terminal Doppler Weather Radars TDCA and TADW all indicated strong rotation over this area.

The tornadic damage ended near the north end of the Naval facility, and no damage was noted in the adjacent residential community to the north. Many other scattered trees were knocked down all across Calvert County and lower southern Maryland due to winds associated with Tropical Storm Isaias.

Location Date/Time Deaths & Property & Event Type and Details Injuries Crop Dmg At 7:33 AM EDT, an EF-1 tornado came onshore at Plum Point near Beach Drive approximately 5 miles east of Huntingtown, MD. The tornado moved west along Shore Drive, uprooting numerous trees and snapping and twisting others. A large tree halfway along Shore Drive fell on a house, causing structural damage. The tornado proceeded to move to the end of Shore Drive and shifted southwest along Ridge Road causing trees to snap about 20 feet up and fall in multiple directions. Some trees that were snapped were a foot and a half in diameter.

The tornado then moved across Plum Point Creek and the grassy wetlands toward Tobacco Road. A swath of trees had their tops broken off east of Tobacco Road and fell mainly in a south to west direction.

The tornado then proceeded up Tobacco Road near Tobacco Lane, and moved northward towards Breezy Point Road. Peak winds in the tornado were estimated to have reached 90 mph here. Over 30 trees were uprooted, and some were broken in half. A house had a tree fall on it along the Tobacco Road area, and windows were blown in on another house. Tobacco Road had over 10 trees fall westward over the road along with multiple power poles. A 75 to 100 yard path of tree damage was observed east of Tobacco Road with trees falling in multiple directions. The area of Tobacco Road from Pinewood Terrace to Tobacco Lane became impassable due to the tree and power line damage, and the Breezy Point area became cut off from the main road.

The tornado moved west after passing Breezy Point Road and caused numerous trees to fall along Route 261/Bayside Road near Bristol Drive. A large tree near the intersection of Route 261 and Bristol Drive fell on a house. The tree damage path was observed up to 50 to 75 feet down the north end of Bristol Drive.

The tornado then crossed MD-261, downing more trees and tearing siding from homes near the intersection of Holbrook Lane and Pleasant Court. One tree fell into a house, knocking out a window. No further tornadic damage was observed beyond this point.

Location Date/Time Deaths & Property & Event Type and Details Injuries Crop Dmg A supercell thunderstorm spawned two tornadoes during the afternoon of Thursday, August 6th. The first tornado touched down along Hatchery Road, near Harriston in Augusta County Virginia. Numerous trees were uprooted and large branches snapped along the tornado`s path as it moved to the east-southeast. Trees fell in multiple directions in a generally convergent nature over a path about two and a half miles long. Notably, many trees fell towards the south while the parent storm`s motion was toward the east, indicating a rotating vortex in contact with the ground. NWS 88D Doppler Radar showed rotation directly over this area.

There was tree damage noted along Rockfish Road and crop damage along Patterson Mill Road. The tornado then moved across US-340 East Side Highway where at least one tree fell on a vehicle, but no injuries were reported as a result. It then moved into the Jollett Springs Mobile Home Park, where several trees were uprooted, and one snapped. At least one mobile home had damage to its facade when an awning blew off, as shown by a picture taken by local broadcast media.

Sporadic straight-line tree damage was noted north and east of this point, and although KLWX WSR-88D continued to show rotation several thousand feet above ground level, no discernible tornadic damage was noted east of the mobile home park from this tornado.

The second of two tornadoes spawned by a supercell thunderstorm on the afternoon of August 6th occurred over Broadus Wood Elementary School on VA-663 Buck Mountain Road in Earlysville, Virginia. It was on the ground only briefly, uprooting several trees, and snapping two, in a convergent manner over a brief path on and adjacent to the elementary school grounds. While there was fencing damage on the school grounds, no damage was noted to the school building.

This tornado was embedded in a larger area of intense straight- line winds that produced numerous instances of downed trees across Free Union, Earlysville and Hollymead just northwest of Albemarle County Airport. NWS 88D Doppler Radar showed persistent rotation in this area, but the only evidence of tornadic damage on the ground was over this brief path.
