What a wild day yesterday! By my count, the National Weather Service forecast office in Sterling issued 23 tornado warnings, 33 severe thunderstorm warnings, and 8 flash flood warnings between 2 and 10 p.m.
Heavy rain and flash flooding turned out to be the biggest impacts from this storm, but there were scattered wind damage reports, numerous funnel cloud sightings and likely at least a few small tornadoes. We await official storm surveys from the National Weather Service for confirmation.
In the D.C./Baltimore area, the National Weather Service has logged 21 wind damage reports, mostly downed trees and power lines. However, there were at least two reports of structural damage:
* In Aldie, Va (Loudoun co) there was damage to outbuildings
* In Remington, Va. (Fauquier co.) damage was reported to 6-12 homes.
Four funnel clouds sightings were reported in the area - two in the vicinity of Damascus (Montgomery co), one in Frederick co. and one in Severn (Anne Arundel county).
A tornado was reported on the premises of BWI Airport, but there was no damage indicated.
At least 25 reports of flash flooding have been documented scattered throughout the region. The most notable flash flooding incident occurred in Prince George’s where the fire department had to rescue three teens. Watch the dramatic video.
Large hail reports were few and far between. They mostly originated from central Virginia.
Rainfall amounts were highly variable and heavily dependent on the track of thunderstorms. An overall overage was 1-2” in the immediate mero region, but some spots (mainly well west and southwest of D.C.) received less than 0.5” and a few areas got 2-4”..
Here are a few select high-end totals:
Mt. Airy: 3.24”
Oxon Hill: 2.60”
