WASHINGTON — After an onslaught of showers and storms Wednesday night, Thursday offered some dry relief to a region weary from flooding.

But more wet weather, unfortunately, is likely in the days ahead.



“The driest first half of July on record has now been replaced by the wettest second half,” said Storm Team4 Meteorologist Chuck Bell.

Rainfall totals for the month of July amounted to 15.43 inches at BWI Marshall Airport, 9.69 inches at Dulles International Airport and 9.19 inches at Reagan National Airport.

Since Saturday alone, rainfall totals at BWI Marshall add up to 11.17 inches; at Dulles, a total of 7.7 inches of rain fell upon the area. Reagan National had a total of 6.4 inches of rain since Saturday’s washout.

But even as the rain finally moves offshore, there may still be residual flooding as the waters recede. The ground is already soaked, so the water has no place to go. It makes the threat of thunderstorms Friday night particularly menacing.

Roads were underwater and waterways overflowed across the D.C. region Wednesday night, and the National Weather Service continues to advise people to steer away from flooded areas as rainwater runs off.

The National Weather Service said some area streams and creeks rose 4 to 7 feet in an hour Wednesday night. Sligo Creek in Takoma Park, Maryland, and Rock Creek in D.C. surpassed their flood stages by around 8:30 p.m., according to the weather service.

Montgomery County officials shut down intersections on parts of Beach Drive and Sligo Creek Parkway because of flooding and stranded vehicles.

In Alexandria, Virginia, Four Mile Run rose from about 4.3 feet at 7:16 p.m. to 10.6 feet at 7:27 p.m., the weather service said.

The weather service is also warning residents of the threat from trees toppling because of the heavily saturated ground from all the recent rain. Trees can fall over with little or no wind in these conditions, the weather service said.

A woman was killed Monday night after a tree fell on her home in Burke, Virginia.

As a precaution, Montgomery Parks has closed all natural surface trails to the public until further notice. Excessive rain may create dangerous conditions for park users as well as affect the integrity of the trails. Paved trails remain open.

Drivers should stay alert when going through wooded areas for the potential of downed trees.

Traffic and transit

Flooding and downed trees have caused some major problems on local roads.

Downed wires have closed Russell Road in Alexandria in both directions at West Windsor Avenue.

In D.C., rain and heavy flooding prompted water rescues. On Grant Road and Davenport Street in Northwest, a mail truck overturned into a waterway; D.C. Fire and EMS said the driver is safe. Also, at Grant Road and 27th Street, still in Northwest, two people self-evacuated from a car and sheltered nearby.

The Rock Creek Park area in D.C. is “very hazardous,” according to D.C. Fire and EMS.


D.C. police also reported high standing water in Northwest on Broad Branch Road between Brandywine and 27th streets Wednesday night. All lanes continue to be closed Thursday because of a downed tree.

Multiple water rescues also happened across Montgomery County, Maryland.
