Post-storm flooding in DC area brings traffic woes and delays Saturday evening

Severe storms and flash floods in the D.C. area created hazards on both major roadways and urban streets Saturday evening.

Listen to Saturday’s 11 p.m. weather update:

Floods and flash floods caused major delays and confusion on area roadways. High waters blocked parts of US-1 Baltimore Avenue between Knox Rd and College Avenue, The Beltway Outer Loop saw the lanes blocked near MD-450, and large areas of standing water caused hazards on the GW Parkway in Virginia, especially near the turnoff for the American Legion Bridge and between Alexandria and Mt. Vernon.

Rt. 3 near the Chesapeake Bay Bridge also saw major flooding that blocked traffic. Read more on area traffic during the storms here.

The rains also caused delays and cancellations for sports events throughout the region, including at Nationals Stadium.

Other heavy storms that could “pack a punch,” may come through later Saturday evening, StormTeam4 meteorologist Amelia Draper said.

As fleeting as some of these storms can be, recent history shows how quickly they cause severe damage.

StormTeam4 meteorologist Mike Stinneford said a stalled front to the south will continue to keep the weather in the area unsettled for the next several days.

There’s an even higher chance of storms popping up late in the day on Sunday. Some of those storms could continue overnight into Monday morning.

The chance of storms holds through Monday, but the weather should dry up by Tuesday.


SATURDAY NIGHT: Showers and storms ending; partial clearing with patchy fog. Upper 60s in suburbs AND lower 70s in D.C.

SUNDAY: Partly to mostly sunny, hot and humid with PM storms, some strong and lasting late. Temps: Mid to upper 80s.

MONDAY: Partly sunny with PM storms, some strong to severe with heavy rain. Temps: Mid to upper 80s.

TUESDAY: Mostly sunny, dry, hot and humid. Temps: Around 90.
