Soggy Sunday: Showers, thunderstorm cloud DC region

The National Weather Service has issued a flash flood watch for the D.C. area until 5 a.m. on Monday. Showers and thunderstorms are expected to hit the D.C. area on Sunday afternoon. The new round of rain combined with all the rain from Saturday could lead to flash flooding. Here's what you need to know.

WASHINGTON — National Weather Service forecasters are asking residents in the D.C. area to be vigilant as storms rumble through the area Sunday night.

The weather service issued a flash flood watch for the D.C. area until 5 a.m.

It also issued a flood warning for Maryland’s Frederick County until 11 p.m. and flood warnings for Anne Arundel, St. Mary’s, Calvert, Prince George’s and Charles counties until midnight.



A flash flood watch means that conditions might develop that lead to flash flooding. The weather service said the fact the ground in a lot of areas is already soaked and several streams and creeks are swollen from the rain on Saturday could lead to flash flooding.

Sunday started out nice with peeks of sunshine, what Storm Team 4 meteorologist Lauryn Ricketts said may be the only sliver of sunshine until later this week. Showers and storms started shortly before noon.

Storm Team 4’s Somara Theodore said that Sunday’s rain differs vastly from the Saturday’s batch of storms that brought record-breaking rainfall totals.

“The rain is not widespread and steady like yesterday,” said Theodore. “Areas already exacerbated by Saturday’s record-breaking rain could see more downpours.”

Theodore predicts most of the severe activity will stay east of Interstate 95 through the evening. Heavy showers will linger overnight and humid conditions will remain.

Saturday’s rain totals reached 4.6 inches in D.C., 6.5 inches in Montgomery County, 5.5 inches in Prince George’s County, 6.5 inches in Fairfax County and 5.5 inches in Prince William County, the National Weather Service reported.

 

Current conditions

Forecast

As for the week ahead, the stormy pattern may continue until Thursday, but even Friday has a slight chance of isolated activity, according to Theodore.

“We are stuck in this prolonged pattern as moisture will continue to feed right into the region from the south,” Storm Team 4 meteorologist Lauryn Ricketts said. “Any storms and rain showers will become more scattered in nature on Thursday as the pattern begins to break down.”

Until then, Ricketts said to expect rain chances daily.

  • Monday: Cloudy with some showers and scattered storms. Highs in the low 80s.
  • Tuesday: Gray with showers and storms. Highs in the mid 80s.

Traffic

Saturday’s rains caused multiple street closures, delays and water rescues due to flooding. Fire departments in Virginia and Maryland counties reported many motorists who had to be rescued when their vehicles got stranded on flooded streets.

The rain compounded delays on roads undergoing scheduled repairs and crashes were reported throughout Saturday, though by Sunday morning the roads were in slightly better shape.

Flooding conditions have suspended MTA service from Patapsco to Cromwell and BWI Thurgood Marshall Airport stations. Shuttle bus service will be available.
