The National Weather Service (NWS) said “damaging wind gusts” could be caused by an isolated tornado. Heavy rains and thunderstorms are also threatening to savage the area. The warnings will stay in place until 3am (8am BST).
The news comes after the stars of golf were forced to complete the final round of this year’s Masters at Augusta early due to the weather concerns.
The nail-biting final round was eventually won by American Tiger Woods, who claimed his first major honour since 2008.
On its website, the NWS reported: “This Hazardous Weather Outlook is for eastern West Virginia, northern and central Virginia, and central and western Maryland with the exception of Garrett County.
“A Tornado Watch is in effect for the entire outlook area until 3AM.
“Two rounds of showers and scattered thunderstorms are expected this evening and overnight.
“The main severe weather threats are damaging wind gusts and an isolated tornado.
“Heavy rain in thunderstorms may lead to isolated instances of flooding.”
The NWS says that Monday through to Saturday residents in those areas should expect isolated wind damage possibly tomorrow.
It adds that gusts of wind up to 50mph could ravage parts of western Maryland, eastern West Virginia and northern Virginia.
Reports suggest that Virginia averages three tornadoes in April.
September is the worst struck month with four occurring.
