A flash flood watch is in effect across Central Maryland through late Tuesday, with storms and heavy rain possible. A burst of heavy rain inundated College Park and surrounding areas Tuesday morning.
The watch is in place across greater Baltimore. The air is thick with moisture around the region, with a dew point of 72 degrees Tuesday afternoon at BWI Marshall Airport, an oppressive level of humidity.
Chances of storms and heavy rain showers are expected through Tuesday night.
Flash flood-related speed restrictions have been issued that could cause 10-15 minute delays on MARC trains between Washington and Muirkirk on the Camden Line Tuesday afternoon and throughout the evening, the Maryland Transit Administration said.
A band of heavy rain passing through College Park and surrounding areas on Tuesday morning caused flash flooding that submerged busy traffic corridors and trapped some motorists, according to the National Weather Service and local emergency officials.
The weather service has issued a flash flood warning in central Prince George's County and in Washington. A flash flood watch was issued for much of central Maryland, including the Baltimore region, though late Tuesday night.
Police in Washington reported high standing water along Route 295, while the Prince George's County Fire Department reported flooding in Berwyn Heights and College Park.
Mark Brady, a spokesman for the department, posted on Twitter that the hardest hit area was the 8900 block of 59th Avenue in Berwyn Heights, where homes and roads were flooded.
Brady posted an image on Twitter of two vehicles stuck in high water on Paint Branch Parkway in College Park, and reported a fallen tree on top of another vehicle on Central Avenue in Largo. Others posted images of high water on Route 295.
The College Park Fire Department reported conducting "numerous water rescues," also via Twitter.
No injuries had been reported as of 11:30 a.m.
The county fire department set up an area command unit in College Park to organize its response to the flooding and calls for assistance from motorists.
Traffic was slowed on many area roadways as the intense rain moved through the area. Brady reported the rains had stopped for the time being about 11 a.m., and that the water was receding.
