Heavy Rain Brings Flooding to Middle Atlantic

20 Aug 2021, 4:40 pm

A slow moving trough/front coupled with gulf moisture, will continue to enhance rainfall across the Eastern United States with the potential for flooding.

Flash Flood Watches are in effect tioday for most of the Middle Atlantic from Delaware Bay to the Hampton Roads.

The excessive rainfall outlook includes a slight risk of flash flooding for coastal areas of Delaware, Maryland, Virginia and North Carolina with a marginal risk westward to the mountains. For Saturday, areas from Chesapeake Bay into New York have a marginal flooding risk.

Pockets of 2-4 inches of rain can be expected with isolated higher totals possible, potentially over 6 inches where multiple thunderstorms form.

Showers and thunderstorms will increase through the afternoon, bringing pockets of heavy rain and the risk of flooding. A number of flash flood warnings were in effect earlier in Washington, DC for heavy rain and flooding.

Storm coverage will decrease into Saturday morning, but a few areas may continue to see heavy rain. The wind flow will shift for Saturday with an onshore flow ahead of Henri. That’ll keep humidity levels high with the threat for more storms, with coverage gradually shifting northward.
