DC region to experience very humid conditions with air temperature reaching 100

Another wet day, high temperatures and the possibility of afternoon thunderstorms for the DC area on Tuesday.

Another day of humid conditions, high temperatures and the possibility of afternoon thunderstorms is forecast for the DC area on Tuesday. Here’s what you need to know.

The humidity in the atmosphere will create humid conditions to start the morning and continue through the afternoon. Due to the humidity, the air temperature will feel above 100 degrees outside, said Storm Team4 meteorologist Ryan Miller.

“So be mindful if you spend time outdoors and then in the heat,” Miller said. “Stay loose, [wear] light clothes and also stay hydrated and take a few breaks in the air conditioning.”

DC activated its heat emergency plan and encouraged residents to stay indoors. DC residents could also go to one of the District cooling centers.

Miller said temperatures will drop to 90 degrees on Wednesday, with a risk of thunderstorms entering the region via a cold front passing before the evening hours. However, the cold front will bring cooler and less humid conditions for the remainder of the week.

Despite cooler temperatures arriving later in the week, they aren’t expected to stay long, said Storm Team4 meteorologist Chuck Bell.

“It’s starting to be ‘that’ time of year. The statistical peak of hurricane season is around September 10, so there is plenty of time left in hurricane season,” Bell said.



Flooding issues remain

Between one and four inches of rain fell Monday in Prince George’s County, Maryland, causing flooding on roads. Flash flooding has been reported in the Riverdale area, with rapidly rising waters making roads impassable, Miller said.

Two people were stuck in their cars and had to be recused in the parking lot near the Crestwood Medical Building in Riverdale after flash flooding reached up to 5 inches, OMCP’s Kyle Cooper reported.

Why has the DC region experienced a recent spate of flooding issues?

“Well, you have the combination of impermeable surfaces, plus aging infrastructure, plus the increase in flash floods,” said Dave Dildine, OMCP traffic reporter from the DC area. with over 12 years of road and weather reports.

Storms that release inches of rain over a short period of time can cause flash flooding issues in any small trough or low point on area streets.

Some fixes are underway, Dildine said, including cleaning flood-prone storm sewers and the new DC Water tunnel in the Bloomingdale area. However, residents have a role in safety and should pay attention to flash flood warnings.

“If you don’t act fast, and I mean fast, you’re going to be underwater, and you’re going to be on an inflatable boat that will be taken out of your car,” Dildine said.
