Grab your umbrellas and rain boots this evening, and be careful tonight and early tomorrow morning.
Montgomery County is in for heavy rains and possible flash floods, according to the National Weather Service. The NWS issued a flash flood watch for the county from 3 p.m. today until 6 a.m. Thursday.
Expected heavy rains may have the potential to cause severe and/or unexpected flooding within the next 24 hours.
Flash floods kill more people every year than any other weather hazard, according to the NWS.
The alert advises drivers to not pass through flooded areas. As little as 2 feet of water can sweep a vehicle off the road.
Meanwhile, Montgomery County Police issued their own alert, warning drivers to consider alternate routes before traveling, to keep safe distances between vehicles, not driving through flooded road and to stay alert.
Police also advised commuters to call the police non-emergency number at 301-279-8000 if they encounter high water, downed trees, or wires, so that emergency personnel are aware of the issue.
