Scattered showers and severe storms brought occassional downpours for days, so flooding remains a concern in the D.C. area.
A costal flood warning issued for D.C. and Alexandria, Arlington and Falls Church in Virginia has been extended to 2 a.m. Saturday. Water levels at the Wisconsin Avenue gauge are expected to reach 8-9 feet Thursday night and Friday. On April 18, when Washington Harbour in Georgetown flooded because the floodgates weren't closed, the peak was 8.97 feet.
That large, persistent area of low pressure hovering over the area began to clear out Thursday, but there's still a 30 percent chance of rain in the area Friday, NBC Washington meteorologist Doug Kammerer said. The Potomac River should peak in the next 24 hours.
Many area creeks and streams have been running high, so people in flood-prone areas have been warned to be prepared.
