DC area faces flash flooding, damaging winds as severe storms strike

The D.C. area is facing heavy rain and damaging winds Tuesday night into Wednesday as severe thunderstorms roll through the region. Here’s what you need to know.

Quarter-sized hail and 60 mph winds are possible.

Between 1.5 and 3.5 inches of rain have already fallen in the affected area, and additional amounts of 0.5 to 2 inches are possible, according to the weather service. Flash flooding is ongoing or expected to begin shortly.

The weather service reminded residents that most flood deaths occur in vehicles: “Turn around, don’t drown” if you encounter flooding on roadways.

“At this time, the heaviest and worst of storms is expected between 8 p.m. [Tuesday] and 3 a.m. Wednesday,” said 7News First Alert Chief Meteorologist Veronica Johnson.

Johnson said there is a “moderate threat” of damaging winds and flash flooding, with rain rates over one inch per hour in certain areas. This increases the risk of ponding — when flooding occurs in relatively flat areas like roadways where motorists risk hydroplaning.

The Federal Aviation Administration issued a ground stop for the Reagan International Airport shortly before 8 p.m., preventing inbound flights from landing there until 11:15 p.m.

Showers should ease by 10 a.m. Wednesday, according to Johnson.

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
