A few northwest winds around 20 mph and occasional clouds will help you feel less sweaty. There is a slight chance of late thunderstorms and cool showers.

A ‘Hot Weather Emergency’ has been declared by DC
DC has Major Muriel E. Bowser A “climate emergency” was declared Today through Thursday. The declaration allows more cooling center locations to open during this heat wave and some cooling sources to stay open longer (24 hours, in some cases). Locate the cooling core heat.dc.gov or by calling 311. By midweek, heat index values in the mid-100s are possible as temperatures approach record highs, albeit without humidity.
In a news release, the mayor’s office offered the following advice to protect yourself and others from extremely hot weather:
- Stay indoors if possible: Find places in the shade or with air conditioning to get relief from the heat.
- Check your neighbors: Young children, the elderly and those with access and functional needs are among the most vulnerable in our community.
- Drink plenty of fluids: Increase your fluid intake, but don’t drink alcohol, caffeine, or fluids with high sugar content.
- Keep pets indoors: Walk pets early in the morning, give pets plenty of water, and don’t leave pets in vehicles, which can reach dangerous temperatures within 10 minutes. For all animal emergencies, including extreme temperatures or animals left outside in vehicles, call the Humane Rescue Alliance at 202-723-5730.
- Wear appropriate clothing and sunscreen: Choose lightweight, loose-fitting, light-colored clothing and wide-brimmed hats.
The mayor’s office encourages anyone, especially families, to dial 311 seeking emergency shelter, and to call 311 or 202-399-7093 if they see someone struggling with the heat.
