A flash flood watch is in effect for Carroll County and much of Maryland until 10 p.m. Sunday, according to the National Weather Service (NWS).

During a flash flood watch, creeks and streams may rise above their banks onto roadways.

Areas under the Aug. 26 flash flood watch may receive 2 to 3 inches of rain at one time, reports the NWS. Drivers should use caution and turn around if they see roadways covered by water, said officials with the NWS.

The Federal Aviation Administration advised that flights out of BWI were delayed Sunday afternoon as a result of the weather.
