The National Weather Service said Wednesday night that a weather spotter reported a possible tornado touchown in St. Mary’s County.

The weather service said the spotter saw a “tornado snapping several trees with roaring wind” shortly before 8 p.m. along Route 5 near the intersection with Lightfoot Way, which is several miles southeast of Leonardtown. But state police and county officials reported no reports of serious storm damage.

The weather service issued several severe weather warnings and watches throughout Wednesday evening across the Washington area, including flash flood warnings for the District and immediately south of the city. A tornado watch was issued for areas of southeastern Prince George’s, Charles and St. Mary’s counties until about 10 p.m.
