Washington starts Thursday under cloudy skies. The day should stay dry.

Tidal Flooding Threatens Low-Lying Shorelines

A Coastal Flood Advisory remains in effect through 9 a.m. Friday for the District shoreline, with up to 6 inches of water expected in low-lying areas around high tide. The National Weather Service says flooding is expected at the unprotected Southwest Waterfront near the D.C. Seafood Market, with water also approaching parts of Hains Point Loop Road and Fletcher's Boathouse; portions of Roosevelt Island are flooded. Drivers should avoid barricades and never drive through water of unknown depth.

Drier, Warmer Friday

Friday will be drier and warmer, with a high of about 69 degrees. Saturday should remain sunny and mild.

Weekend and Early-Week Outlook

The broader forecast looks toward the weekend and early next week.

The broader weekend forecast carries some track uncertainty, with breezy conditions possible. That marks a substantive change from Wednesday's Hoodline forecast, which focused on lingering rain and clouds before the weekend break.
