WASHINGTON, D.C. — A Heat Advisory is in effect across the D.C. metro area, central Maryland, and northern Virginia, with a dangerous heat index of 105°F forecasted for Thursday from 11 a.m. to 8 p.m., according to the National Weather Service.
The extreme heat is expected to raise health risks and strain local power grids as residents face the hottest temperatures of the summer so far.
Counties and Cities Under Alert
The heat advisory covers a wide region, including:
- District of Columbia
- Southern Baltimore
- Prince George’s, Anne Arundel, Charles, St. Mary’s, Calvert, Southeast Harford (MD)
- Fairfax, Arlington, Stafford, King George (VA)
Officials warn that prolonged outdoor exposure — especially during afternoon peak hours — could lead to heat exhaustion or heat stroke, particularly for:
- Children
- Seniors
- Individuals without air conditioning
Health and Safety Guidance Issued
Authorities urge residents in Washington, Baltimore, and surrounding suburban corridors to follow essential precautions:
- Stay indoors when possible, especially from noon to early evening
- Hydrate frequently, even if you don’t feel thirsty
- Wear light, breathable clothing and avoid dark colors
- Reschedule strenuous activities for early morning or post-sunset hours
- Never leave children or pets in parked vehicles
Cooling centers have been opened across several counties, and local utility companies are bracing for high electricity demand as air conditioner usage surges.
More Extreme Heat May Be Ahead
Thursday’s heat levels rival the intense mid-July heat waves the region has seen in recent years. While the current advisory is set to expire at 8 p.m. Thursday, forecasters caution that additional advisories are possible if temperatures remain elevated into the weekend.
