The hot and humid weather brought more storms into the D.C. area Tuesday afternoon, with heavy rain and lightning in some parts.
The heavy rain caused flooding in parts of the area.
At least one driver had to be rescued from their vehicle when Broad Branch Road flooded near 27th Street NW.
A large tree crashed down near 30th Street NW, damaging at least two homes. The soggy ground and heavy, wet branches likely contributed.
No injuries were reported.
The effects of a nearby lightning strike forced officials at Fort Meade to cancel its National Night Out festivities.
Post spokeswoman Mary Boyle said the event was already delayed for 30 minutes Tuesday because of weather. She said four people suffered secondary effects of lightning, and one of them was taken to Baltimore Washington Medical Center for treatment. No serious injuries were reported
Boyle said officials tried to wait out the weather, but when it became apparent that it wasn't going to change, the decision was made to cancel. She said there would not be a makeup date for this year.
Temperatures hit the low 90s Tuesday afternoon and the heat index soared to near 100 degrees before the storms rolled in. The sun and humidity will return before the end of the day, but Storm Team4 will be tracking the chance of more showers and storms later Tuesday evening.
The District activated its heat emergency plan late Tuesday morning. Officials were encouraging people to stay in the shade or in air-conditioning and to keep hydrated. Those needing a place to cool off can visit a D.C. recreation center, public library or senior wellness center. See a map of D.C.'s cooling centers here.
There's a 50 percent chance of storms Wednesday afternoon and into the evening, and some could be strong and potentially severe. The biggest threat from the storms will be heavy rain.
Temperatures will hover around 90 on Thursday and Friday. Storm Team4's Amelia Draper said both days are expected to dry and humid, but there may be a chance of thunderstorms in the evening.
