What to know: Rails, roads and forecast

Cleanup will continue Friday after heavy rains and flash flooding caused problems across the D.C. region Thursday, including several dramatic water rescues.

The good news is that a lot of the floodwaters receded overnight and the weather will be less humid and cooler.

LOTS OF CALLS FOR HELP

Thursday’s storms left roads drenched in parts of the D.C. region.

In Maryland’s Prince George’s County, Fire and EMS spokeswoman Jennifer Donelan said that in over 4 1/2 hours Thursday, the department received over 250 calls for service, and 134 of those where water-related. The exact number of how many people were rescued from their vehicles is not yet known, but there was only one person that needed to be transported, Donelan said.

In Montgomery County, in a three-hour period Thursday afternoon, emergency responders received about 150 calls for cars stuck in high water or water rescues, Fire and Rescue spokesman Pete Piringer said in a video update on Twitter.

In the District, D.C. Fire and EMS responded to a number of water rescues in Northwest and Northeast.

Severe flooding also caused MARC trains between New Carrollton in Prince George’s County and Union Station in D.C. to hold.

Amtrak service to and from D.C. was stopped due to flood water on the tracks, leading to hourslong delays.

FORECAST

Friday will be cooler courtesy of a stalled cold front to the south. Behind that front is dry air that will filter in.

A few showers are possible on Friday, mainly near the front over the southern suburbs, Storm Team4 meteorologist Mike Stinneford said.

A few showers are also possible on Saturday. Showers and storms will become likely on Sunday as another cold front comes, with showers ending on Monday as the front comes through.

  • Friday: Mostly cloudy. A few showers are possible, mainly south. Turning less humid. Highs 75 to 80.
  • Saturday: Mostly cloudy and less humid. A few showers are possible, mainly south. Highs 75 to 80.
  • Sunday: Partly sunny and more humid. Showers and thunderstorms, mainly in the afternoon and evening. Highs upper 70s to lower 80s.
  • Monday: Partly sunny with a chance of showers. Highs upper 70s to lower 80s.
