A flash flood watch has been issued for Prince George's County and most of the region beginning at midnight extending until through Thursday evening, reports the National Weather Service.
Showers and thunderstorms producing heavy downpours are expected in the region this evening, with more than one inch of rain possible overnight, according to NWS. Forecasters are calling for a storm that may be on par with last summer's derecho, and warning residents to be prepared.
A second round of storms is expected to sweep through the region on Thursday, possibly dumping an additional one to two inches of rain.
"With the ground already saturated from heavy rainfall during the past week...only an inch of rainfall in an hour could produce flash flooding of streams and low lying areas," according to the alert issued by NWS.
