EF1 tornado in Calvert County, Maryland

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.

Tropical Storm Isaias moved up the east coast, passing through southern Maryland on the morning of Tuesday, August 4th, 2020, spawning several tornadoes as well as flooding rain and tropical storm force winds.

Storm total rainfall ranged from 2 to 4 inches near Interstate 95 to as much as 9 inches in Calvert County east of Interstate 95. The heavy rain led to numerous incidents of flooding and flash flooding, especially near and east of Interstate 95.

The highest sustained wind of 46 knots was reported at Bishops Head and the highest peak gust of 63 knots was also reported at Bishops Head.

There were three tornadoes associated with Isaias over southern Maryland and there were also numerous reports of downed trees from tropical storm force winds, especially near and east of Interstate 95.

A storm surge of 1 to 2 feet occurred along the western shore of the Chesapeake Bay and the shore of the Tidal Potomac River. This did result in minor tidal Flooding in Washington DC.
