Flash flooding was expected across Baltimore County Wednesday night, according to the National Weather Service, which issued a flash flood warning from 7:30 to 10:30 p.m. for the county and city.

Officials said they issued the flash flood warning Wednesday because radar showed thunderstorms with heavy rain across the area. Flash flood warnings are issued when a rapid rise in water level is imminent.

During a flash flood warning, drivers who come across water-covered roads should turn around; don't drown. Those in flood-prone areas should move to higher ground. Pedestrians should not walk through flood waters.

Locations that may get flooding include Baltimore, Pikesville, Middle River, Cockeysville, Millers Island, North Point State Park, Sparrows Point, Back River, Dundalk, Towson, Catonsville, Essex, Woodlawn, Randallstown, Parkville, Owings Mills, Eldersburg, Carney, Milford Mill and Perry Hall.

Because the ground is already saturated, heavy rain could lead to flash flooding. Roads and poorly drained areas can quickly become inundated during a flash flood. Streams and creeks could leave their banks, flooding nearby properties.
