Flash flood watches and warnings covered all of central and southern Maryland and northern Delaware on Wednesday. The National Weather Service said 3 to 5 inches of rain had fallen over the Baltimore-Washington area, causing streams to overflow and closing numerous roads. Road flooding was also reported in northern Delaware.
Rain was expected over the next several days.
“I don’t think it will be quite as widespread as we saw this afternoon but there’s still going to be locally heavy rains,” said weather service meteorologist Brian Lasorsa.
Minor flooding was expected along the Potomac River from Point off Rocks in Frederick County to Little Falls near the border between Maryland and the District of Columbia. The highest water is expected Thursday night through Friday afternoon as the crest moves downstream. The weather service also predicted minor to moderate flooding on Potomac River tributaries including Antietam Creek, Seneca Creek and the Monocacy River.
Maryland Natural Resources Police said boating and other recreational uses of the upper Potomac River and its creeks and streams should be avoided. The advisory runs through Friday, and police said it would be updated if necessary. Rain has made river levels hazardous in the main stem of the upper Potomac from Cumberland to Little Falls.
The Avalon area of Patapsco Valley State Park in Elkridge had significant flooding along both the Baltimore County and Howard County sides of the river near U.S. Route 1.
