The damage in Wayne County ranged from torn-off porch roofs to homes that were destroyed Friday night, said Al Lisko, who heads up recovery efforts for the state Division of Homeland Security and Emergency Management.
Wayne was the first seriously affected county that teams could reach. Lisko said he hoped to have a statewide assessment sometime Monday night.
No deaths or serious injuries have been reported from the storms that tore through the hills along the state's border with Kentucky and Ohio. The National Weather Service confirmed an EF3 tornado hit Wayne County, while an EF-2 toppled a 280-foot radio tower in Mingo County.
West Virginia has averaged only two tornadoes a year for the past three decades, according to the agency's Storm Prediction Center.
In all, nine counties were under a state of emergency Monday due to flooding and wind damage from storms last week.
Gov. Earl Ray Tomblin's declaration affects Wayne, Lincoln, Doddridge, Harrison, Marion, Monongalia, Preston, Ritchie and Taylor counties. It allows the National Guard to remove debris, clear roads and otherwise help storm victims.
Tomblin toured some of the areas over the weekend along with state emergency management director Jimmy Gianato and Adjutant Gen. James Hoyer of the West Virginia National Guard.
"To see the devastation that has happened here in Wayne County is just unbelievable," Tomblin told WSAZ-TV. "Our job now is to get people's lives back together as quickly as possible."
U.S. Sen. Joe Manchin, who was briefed on the situation Monday, said West Virginia's congressional delegation will likely seek no- and low-interest loans to aid in the rebuilding, noting that many residents may not have insurance.
"It was unbelievable, the force of this storm," Manchin said.
Sharon Adkins and her twin sister Sheila were at their mother's funeral Friday night when the storm demolished her home in Cove Gap, near East Lynn in Wayne County.
"I've never seen anything like it in my life," Sharon Adkins told WSAZ-TV as she picked through the debris of the house she grew up in. "It's like a war zone.
"Lose my mom and then lose her home ... there are no words," she said. "It's heart-wrenching. It's the worst thing I've ever been through."
Pam Davis, whose brother owns a local grocery store, said a lot of people lost everything.
"But everyone is safe," she told the Herald-Dispatch. "... Homes can be replaced. People can't."
