Washington, DC – A dangerous wave of heat will push temperatures to a 105-degree heat index across the DC metro, central Maryland, and northern Virginia from 11 a.m. to 8 p.m. Thursday, raising the risk of heat illnesses and straining power grids in the region.
According to the National Weather Service, a Heat Advisory remains in effect for the District of Columbia, Southern Baltimore, Prince George’s, Anne Arundel, Charles, St. Mary’s, Calvert, Southeast Harford, Fairfax, Arlington, Stafford, King George, and surrounding counties. The agency warns that outdoor activity during peak afternoon hours could lead to heat exhaustion or heat stroke, especially for children, seniors, and those without reliable air conditioning.
Officials urge residents in Washington, Baltimore, Fairfax, and the entire suburban corridor to stay indoors, hydrate often, and avoid direct sun. If you must work or exercise outside, wear light clothing and schedule strenuous activities for early morning or after sunset. Check on neighbors, especially the elderly or those with health concerns, and never leave pets or children in parked vehicles.
Thursday’s heat will be the highest of the summer so far, rivaling previous mid-July heat waves in the region. Cooling centers are open in several counties, and local utility providers are preparing for possible increased demand.
Dangerous heat conditions will persist until at least 8 p.m. Thursday, with further advisories possible if temperatures remain high into the weekend.
