A wintry mess was bearing down on mid-Atlantic states Tuesday with forecasts of significant snow and ice accumulations prompting warnings of potential power outages.

Travel will become treacherous Tuesday through early Wednesday in much of Virginia and West Virginia the National Weather Service said.

Virginia Republican Gov. Glenn Youngkin on Monday declared a state of emergency ahead of the storm, allowing state agencies to assist local governments. Schools and government offices throughout Virginia were closed Tuesday.

The heaviest snow, up to 10 inches, was forecast in portions of northern and central Virginia and eastern West Virginia. Ice accumulations could range from a glaze in Kentucky and West Virginia to a half-inch in the Roanoke Valley of southwest Virginia, the weather service said. Power outages and tree damage were likely in places with heavy ice buildups.

“Did you think winter was over? Think again!” the weather service’s office in Blacksburg, Virginia, said in a post on the social media platform X.

Appalachian Power, which serves 1 million customers in West Virginia, Virginia and Tennessee, said it has requested 700 additional workers from neighboring utilities to assist with problems by Tuesday morning.

In East Tennessee, forecasters warned that the flood threat will increase throughout the week, with up to 8 inches of rain possible by Sunday. The U.S. Army Corps of Engineers said it was taking steps to capture runoff and mitigate flood risk, including lowering some lake levels.

In northern Virginia, the National Park Service closed a portion of the George Washington Memorial Parkway, a narrow highway that winds through woods along the Potomac River.

The parkway connects national park sites and has been a trouble spot during winter storms for abandoned cars that created a slalom course for snowplows and other vehicles.
