Maryland weather: Flood watch issued for entire region Saturday

Rain and thunderstorms are forecast through Sunday across Maryland, sustaining the threat of more flooding.

The National Weather Service issued a flash flood watch for the entire region Saturday, warning that some areas could see 1-1.5 inches or more of rain. The new wave of storms comes less than a week after flooding devastated Ellicott City and other areas of the Baltimore region.

Friday afternoon, some spotty storms began popping up in Virginia and Pennsylvania, but none had developed in Maryland. Meteorologists estimated 30 percent chances of storms through the afternoon, and 60 percent chances of showers and fog overnight.

Temperatures surged into the mid-80s by late afternoon.

Renta reiterated warnings that, given so much recent rain, the region is unusually flood-prone.

“There’s still some threat,” she said. “Soils are saturated.”

Heavier and more widespread rain is forecast to return Saturday, with a low-pressure system expected to bring back higher levels of moisture and atmospheric instability.

Showers are likely to continue Sunday and possibly into Monday. The weather service predicts as much as 2 inches of rain could fall over the weekend.

The heaviest threats of downpours are expected across Southern Maryland and northeastern Virginia.

The persistence of wet weather comes as Baltimore marks the end of its third-wettest May on record, with more than 8 inches of rain last month at Baltimore-Washington International Thurgood Marshall Airport.
