Washington, DC – Thunderstorms, blistering heat, and dangerous driving conditions hit the DC metro area Tuesday as Maryland braces for an intense summer weather alert. High temperatures will push toward 96°F, with heat index values soaring as high as 104 by midafternoon. Tuesday’s storms could bring brief downpours, gusty winds, and the risk of power outages across key routes like I-495 and local neighborhoods.
According to the National Weather Service, scattered thunderstorms are expected to develop between 2 p.m. and 5 p.m., intensifying through the evening and impacting much of the Washington region. Residents should stay alert for sudden lightning, heavy rainfall, and minor street flooding, especially during the afternoon commute. Light winds will shift south by evening as storms continue into Tuesday night, with a low around 74°F.
Travelers should avoid unnecessary trips during peak storm hours, charge electronic devices ahead of time, and plan for possible delays on major highways. If you need to be outdoors, drink plenty of water and seek shade, as excessive heat can quickly lead to dehydration or heat exhaustion. Power outages and minor property damage are possible in areas with the strongest cells.
