Photos: Potomac River During High Tide Wednesday Morning

The National Weather Service is now predicting "moderate" flooding, along the Tidal Potomac River through Thursday afternoon. Earlier reports warned of "major" flooding, along the Potomac River through Friday.

The Georgetown Waterfront boardwalk is blocked to public access by metal barriers and caution tape. The flood walls remain in place.

Wednesday morning's high tide (pictured here) was an estimated two to three feet above normal because of Sandy. Wednesday around 11 a.m. there was minor flooding along sections of the wooden boardwalk, which was covered in river silt and storm debris.
