Tuesday morning’s heavy rain caused flash flooding in Prince George’s County, prompting some road closures, delays, and speed restrictions for the MARC Camden line.

MARC commuters could experience delays during the evening commute, officials said.  CSX has issued speed restrictions on the Camden Line, between Washington and Muirkirk. Trains will travel at reduced speed so that the operator can stop the train in case a track washout is found, the Maryland Transit Administration said. Delays of 10 to 15 minutes are possible.

If you are driving around Prince George’s, watch out for flooding and high water in some parts of the county. Some towns in northwestern Prince George’s, including College Park and Berwyn Heights, have been dealing with flash flooding as a result of heavy rains Tuesday morning.  Several cars were stalled in high water and the Prince George’s County fire department reports at least two dozen water rescues.

The Capital Weather Gang reports that a flash flood warning has been issued for all but far southern portions of the area through late tonight. More flooding could take place this afternoon.

Prince George’s fire department spokesman Mark Brady said in a tweet the heaviest hit area with homes and roads flooded is the 8900 block of 59th Ave. in Berwyn Heights, where at least two dozen homes have been displaced. Rescuers also were sent to Central Avenue at Watkins Park Drive in Largo where two vehicles were stranded in high water.

The flooding has caused delays on some of the busiest roads in the area including Kenilworth Avenue and East West Highway at Route 1. Paint Branch Parkway is closed, but College Park officials are monitoring the roadway and will reopen it as soon as water levels go down.  Commuters should expect delays in that area. Here is a list of the roads known to flood during heavy rains.
