Flood — May 5, 2025
An area of upper level low pressure brought repetitive rounds of slow moving thunderstorms to parts of Virginia. The heaviest rain fell across Loudoun County, Virginia and King George County, VA where to two to four inches of rain were observed.
Flash Flood — Jul 1, 2023
Showers and thunderstorms developed around a surface trough on the afternoon and evening. Slow moving thunderstorms led to some instances of flash flooding across central Virginia.
Coastal Flood — Oct 29, 2021
A strong pressure gradient between low pressure over the Ohio Valley and strong high pressure over Quebec, CA resulted in a strong southeast onshore flow that brought the highest water levels to the Tidal Potomac River since Tropical Storm Isabel in September 2003.
Flood — Aug 20, 2021
A weak boundary tapped into plenty of moisture and instability for showers and thunderstorms. Weak winds aloft caused slow moving storms, which led to instance of flooding and flash flooding.
Flood — Jun 11, 2021
A slow moving cold front continued to drop to the south and west, but low pressure developed along the boundary and there was still anomalously high amounts of moisture in place. Therefore, more heavy rain developed and this led to instances of flooding and flash flooding.
