A tornado watch was posted for the Eastern Panhandle Sunday, but the only sightings of tornadoes were near New Market, Va., and Charles and Calvert counties in Maryland, said local emergency and weather officials.
Although weather officials were still assessing the situation in Charles and Calvert counties Sunday night, there were instances of "houses knocked down," said Chris Strong, meteorologist with the National Weather Service in Sterling, Va.
At about 4:45 p.m. Sunday, a tornado touched down near Interstate 81 in the New Market area, Strong said.
The tornado damaged four houses and caused a tractor-trailer accident on I-81, Strong said.
The tornado that struck in New Market and Maryland may have been the same, Strong said.
New Market is south of Martinsburg between Winchester, Va., and Harrisonburg, Va.
A tornado watch was posted for the Eastern Panhandle, but it expired at 9 p.m. with no sightings of a tornado, weather and local emergency officials said.
