Heavy, sudden rainfall early yesterday flooded basements and washed out several roads in parts of northwest Virginia, and the Maryland and West Virginia panhandles.

What was left of Tropical Storm Marco dropped more than four inches of rain in some places along a strip extending from Charlottesville, up the Shenandoah Valley to Hagerstown, Md., and including parts of West Virginia, according to a spokesman for the National Weather Service in Washington.

"The worst of it looks like it's over," said Edwin Danaher, a Weather Service forecaster. "The rains were the remnants of Marco. Flash flood warnings have been lifted."

The tropical air mass that originated in the Gulf of Mexico brought unseasonably humid, summerlike weather to the Washington area yesterday, with temperatures reaching 80 degrees. Over the last several days, the air mass has pushed temperatures 10 to 12 degrees above normal, according to the Weather Service.

The heavy rains began shortly after midnight and lasted until about 6 a.m. yesterday. In Front Royal in Warren County, Va., one bridge was flooded and several people had to be evacuated from their homes in low-lying areas, according to Linda Underwood, of the Front Royal Police Department.

"We had some flooding and we had to evacuate some people in town," Underwood said.

Virginia State Police in Culpeper reported some secondary roads out of service and a bridge flooded at Route 621 off Route 55 in Warren County, according to Sgt. F.M. Reynolds.

In Washington County, Md., the rains closed about nine roads and flooded basements, according to the county's fire and rescue department. No injuries were reported.

"I think they rescued a dog from an island," said Dave Pheil, a communications technician with the fire and rescue service. "That's about all."

Maryland State Police in Hagerstown reported some vehicles damaged and incidents of cars left stranded in high waters. No injuries were reported.

Meanwhile, communities along the Virginia coast that had buckled down for an expected onslaught from Hurricane Lili in the Atlantic Ocean were spared any severe consequences when the storm stayed 150 miles out to sea.

Early yesterday, the National Weather Service downgraded Lili to a tropical storm. The Weather Service also dropped all tropical storm watches and warnings for the Virginia coast.

"There is a coastal flood watch and a heavy surf advisory," Danaher said. Lili was more than 300 miles off Virginia's coast and moving due north at 12 miles per hour.

The combination of the approaching storm and the unusual high tides in the bay and ocean increased the threat of flooding, the Weather Service said.
