MARYLAND — The National Weather Service has issued a flash flood watch on the Fourth of July for several counties in central Maryland as well as the District of Columbia and northern Virginia. A watch means conditions could develop that lead to flash flooding.

Torrential rainfall is possible as slow-moving showers and thunderstorms arrive after 1 p.m. on Thursday, July 4, officials advised. More than 2 inches of rain could fall in the downpours, which could lead to a rapid rise in water level, or flash flooding, in small streams and areas that have poor drainage.

There is an isolated threat of scattered thunderstorms with damaging wind gusts.

Afternoon storms will diminish early Thursday evening, according to the flash flood watch.

The flash flood watch applies to Anne Arundel, Baltimore, Howard, Montgomery and Prince George's counties and Baltimore City. It took effect just before 11:30 a.m. and lasts until 8 p.m.
