First we endure days of heat, now there’s dangerous rain.

Emergency officials have reported flooding around the Washington region, with reports of cars being washed off roads in Howard and Northern Montgomery counties.

Heavy rain has been reported around the Springfield Mixing Bowl and along the Interstate 95 corridor between Washington and Baltimore.

Flash flood warnings extend through much of the region until 6:15 p.m.

Drive with caution, especially in areas that are prone to flooding. According to the Federal Emergency Management Agency:
• Six inches of water will reach the bottom of most passenger cars and may cause you to lose control or stall.
• A foot of water will float many vehicles.
• Two feet of rushing water can carry away most vehicles — even SUVs and pickups.

Flooding is likely in low-lying areas and on streets with slow drainage. Additionally, flooded areas may be more difficult to identify at night, they said.

The Maryland Transit Administration reported that both heat and flood restrictions were in place on the MARC Brunswick and Camden lines. The MTA estimated delays may run 15 to 20 minutes for commuters.

Power delays seemed minimal in the Washington area, although BGE was reporting outages for about 4,000 customers in Baltimore City and County.

Flight delays were being reported at many major airports in the eastern portion of the country, including Dulles, BWI, New York’s three major airports, Charlotte and Atlanta.
