Severe storms and high heat hit DC

Tuesday was another hot and muggy day with heat indexes approaching 100 degrees until thunderstorms hit in the afternoon. Keep an eye out for scattered thunderstorms until Tuesday evening.

WASHINGTON — After strong thunderstorms moved through the area, scattered showers are expected to occur in the D.C. area for the rest of the evening.

Earlier, the National Weather Service had issued a severe thunderstorm warning for D.C., parts of Virginia and Prince George’s County, Maryland.

The rain cooled the area down to the 70s and 80s, when temperatures had been climbing into the high 90s earlier in the day.

With heat indexes near 100 degrees, D.C. activated its heat emergency plan during the morning and early afternoon on Tuesday.

The National Weather Service already recorded a heat index of 95 degrees by 9:30 a.m. When the temperature or heat index reaches that level, D.C.’s Department of Human Services and the Homeland Security and Emergency Management Agency will activate cooling centers for residents to seek relief.

Families seeking emergency shelter can call the DC Shelter Hotline at 202-399-7093 or 311 at any time day or night.

You can also find a list of cooling centers on D.C.’s Homeland Security and Emergency Management agency’s website.

The temperatures and heat indexes on Tuesday could potentially be dangerous. Remember to be “heat smart” when working outdoors.

Here are some things you can do to help keep yourself safe:

  • Limit strenuous outdoor activities
  • Don’t leave kids or pets in a closed car
  • Drink more water
  • Drink less caffeine and alcohol
  • Check on senior friends and neighbors
  • Take frequent breaks
  • Get medical help if you stop sweating
  • Adults should take corrective action, and children should seek help, if they feel nauseous, their face feels like it’s burning or they have muscle cramps
  • Make sure outdoor pets have ample shade and water

The Centers for Disease Control and Prevention has specific recommendations for the symptoms of heat exhaustion and the even-more-serious heat stroke.

Heat exhaustion

  • Nausea or vomiting
  • Cold, pale, clammy skin
  • Heavy sweating
  • Fainting

Under those circumstances, you should move to a cooler location, loosen your clothes, lie down, apply wet, cool cloth to as much of your body as possible and sip water. If you continue to vomit, seek medical help right away.

Heat stroke

  • Body temperature above 103 degrees
  • Hot, red, dry or moist skin
  • Fast and strong pulse
  • Possible unconsciousness

Monday saw temperatures get up to 94 degrees at Dulles International Airport, which tied a record for the date set back in 2006 and 2007.

Storm Team4 meteorologist Sheena Parveen said the weather pattern for the rest of the week will be fairly unsettled, which means there is a chance for rain almost every day and temperatures that are slightly above normal.

Temperatures should a bit cooler on Wednesday with highs in the mid to upper 80s with scattered showers and thunderstorms in the afternoon.

Thursday should see temperatures in the mid 80s with another isolated chance of showers and thunderstorms.

If you’re already looking ahead to the weekend, the chance of rain will continue throughout.

“Another weather system passes through across the weekend,” Parveen said. “So as of now, it looks like the highest chance for showers and thunderstorms will be Saturday.”


  • Tuesday: Mostly cloudy with a high near 90 degrees and a chance for thunderstorms in the afternoon. Temperatures will dip to the low 70s on Tuesday night.
  • Wednesday: Mostly cloudy with highs in the mid to upper 80s. Scattered showers and thunderstorms are possible in the afternoon.
