Stormy weather meant lightning and flooding in parts of the D.C. area Monday afternoon, and the National Weather Service issued several flash flood and thunderstorm warnings.
The National Weather Service reported strong storms throughout the area. A strong storm affecting Calvert, Charles and St. Mary's counties in Maryland produced ferquent cloud-to-ground lightning, as did a storm in King George County, Va.
Police reported flash flooding and a vehicle being washed off a roadway after 3 p.m. The heavy rain affected the Interstate 95 corridor between the Washington and Baltimore beltways.
The rain could cause creeks, streams, urban areas, streets, underpasses, drainage areas and low-lying spots to flood. Drivers should not attempt drive on roadways covered by water.
The rain offered relief from the heat, as the temperature dropped below 80 degrees for the first time since early Wednesday morning. Earlier Monday, a hyperthermia alert was in effect due to the heat index reaching 96 degrees before noon.
The humidity remains but will clear out for Tuesday and Wednesday. Expect highs around 92 Tuesday and 93 Wednesday. Then temperatures and humidity will climb back up beginning Thursday.
