These storms will spread across much of the East Coast Monday, becoming most prevalent in the afternoon.
Thunderstorms will extend from Massachusetts to Florida Monday afternoon and into the evening. The storms are not expected to be severe; however, they could contain locally strong wind gusts.
While heat builds in the interior Southeast, along the East Coast, thunderstorms will continue to bring wet weather.
Additionally, the storms over southern Virginia and the Carolinas will be slow-moving, just as these storms were over Georgia on Sunday. This will allow heavy rain to fall over the same area for some time, potentially creating areas of localized flooding.
A few larger cities that could experience this flooding include Danville and Petersburg, Va.; Raleigh, Greensboro and Charlotte, N.C.; and Florence and Columbia, S.C.
Rainfall rates could be as much as 1 inch of rain per hour in this area.
Urban and poor drainage areas will be the most at risk for flooding, including over roadways. Caution should be used through Monday afternoon and into early Tuesday morning.
