MARYLAND — The National Weather Service issued a flood watch for parts of Maryland starting at 3 p.m. and continuing through Wednesday night as 1 to 3 inches of rain are possible within the span of a couple of hours.

Excessive runoff could result in the flooding of rivers, creeks, streams, and other low-lying and flood-prone locations, the NWS said.

The following counties are under the flash flood watch: Carroll, Central and Eastern Allegany, Central and Southeast Howard, Central and Southeast Montgomery, Frederick, Northern Baltimore, Northwest Howard, Northwest Montgomery, Prince Georges, Southern Baltimore and Washington.

"Widespread showers and thunderstorms are expected later this afternoon into the evening. Given a very warm and moist air mass, these will produce some very heavy rainfall at times," the National Weather Service said. "Rainfall amounts of 1 to 3 inches are possible within the span of a couple of hours, with locally higher amounts possible."

The NWS advised residents to check for Flood Warnings throughout the evening, and that those living in areas prone to flooding be ready to take action.

The National Weather Service also issued a Hazardous Weather Outlook for this afternoon and evening for the Maryland portion of the Chesapeake Bay, Tidal Potomac River, and I-95 corridor through central Maryland, Northern Virginia and Washington, D.C. for expected severe thunderstorms.

"Strong to severe thunderstorms will be capable of producing damaging winds, large hail, locally heavy rainfall," the NWS said. "An isolated tornado cannot be ruled out."

There could be flash flooding near and west of Interstate 95 during the storm, the NWS said.
