Forecasters expect another round of isolated showers and flooding on Sunday after severe storms brought flash flood warnings and widespread power outages to the D.C. area the night before. Here’s what you need to know.
7News First Alert Meteorologist Veronica Johnson said that residents across the region should “keep a watchful eye on the sky for the afternoon and evening, there is the threat for some more scattered thunderstorms that may produce some very high winds and heavy rain.”
The National Weather Service says rainfall could bring about another wave of watches for the D.C. area, with a Flood Watch already set for the afternoon in the West, from Hagerstown, Maryland to Harrisonburg, Virginia.
“Like Friday, like Saturday, Sunday will feature more thunderstorms around the area,” Johnson said. “And some of those storms may deliver some heavy rain, enough to give way to some flash flooding.”
The National Weather Service expects new rainfall amounts to be anywhere from a tenth to a quarter of an inch, though higher amounts may be possible in thunderstorms.
Showers and isolated thunderstorms will continue through the early overnight hours before dissipating. A Flood Watch remains in effect through midnight for areas along and west of the Blue Ridge. Visit https://t.co/5RyZgpfrqr for the latest. pic.twitter.com/6v89bstPvk

“The threat for isolated flooding will continue Sunday with deeper and widespread moisture spreading across the area as a weak wave of low pressure tracks along the stalled front,” the National Weather Service said in its forecast. “A few embedded thunderstorms are also possible on Sunday, but the severe threat looks to drop with increased cloud cover and cooler temperatures across the region.”
While afternoon storms remain possible through the start of the workweek, Johnson expects fog to roll in overnight and for temperatures to be cool following record-breaking heat last week.
“As the rain comes to an end, your Monday will start off dry, partly sunny, with just an isolated storm threat for the afternoon,” Johnson said. “Highs 80 to 85 degrees.”
Saturday power issues fade
After thousands across the District, Maryland and Virginia were hit by severe weather that knocked out the power, most area residents have their lights back on early Sunday.
Saturday evening, nearly 15,000 customers across all three jurisdictions were stuck in the dark. Dominion Energy reported about eight thousand of those customers were without power in Northern Virginia’s Stafford, Loudoun, and Fairfax counties. In Maryland, Pepco had close to twelve hundred Prince George’s County customers in the dark for several hours.
