Washington, D.C., is starting Monday, July 6, 2026, on the warm and muggy side, with mostly clear skies and temperatures in the mid-70s. A bit of patchy river-valley fog is possible early, but the real story arrives later in the day as storms redevelop across the region.
Afternoon And Evening: Flood Watch In Effect
Scattered showers and thunderstorms are expected to fire up by late Monday morning and become more widespread through the afternoon and evening. A Flood Watch is in effect from 4 p.m. Monday, July 6, through midnight into Tuesday, July 7, and forecasters warn that repeated heavy downpours could trigger flash flooding in low-lying and poor-drainage areas, according to the National Weather Service.
Rain Amounts And Timing
Multiple rounds of storms are possible, and the strongest cells could drop 2 to 3 inches of rain per hour, especially in slow-moving or “training” storms. The most intense rain is expected from late afternoon into Monday evening, with additional chances for showers and storms lingering through Tuesday. Urban, basement, and roadway flooding are the main concerns. Avoid driving through standing water, and if you live in a spot that tends to flood, move valuables off the floor before the heaviest rain arrives.
Commutes And Events
Monday’s weather could pile on to an already tricky commute as the summer Red Line shutdown kicks off July 6. Shuttle buses and lane changes are expected to carry extra loads during peak hours, and heavy downpours may mean slower shuttle trips and localized flooding on key routes. Build in extra travel time and check for service alerts before heading out. For details on the Red Line work, see FOX5 DC.
Plan Ahead
If you have outdoor plans this afternoon or evening, be ready to move them inside or shelter quickly. Events that depend on dry conditions are likely to see delays or cancellations. Keep phones charged, steer clear of flooded roads, and stay alert for any Flash Flood Warnings, which would override the current watch if storms intensify. For flood safety tips, follow guidance from the National Weather Service and local emergency managers.
