National Weather Service Warns of Possible Minor Flooding in Coastal Areas

The District is under a coastal flood advisory until noon today due to unusually high tides.

The National Weather Service warns that coastal areas in the District may experience minor flooding during high tide this morning as tides are about 1.5 feet higher than normal. An advisory is the least severe type of flood warning that the NWS issues, indicating a risk of minor “nuisance flooding” in low-lying waterfront areas.

According to the advisory, the risk for flooding will be highest during high tide around 10 a.m. this morning.

Unusually high tides called king tides are common along the East coast in the fall, according to the Washington Post’s Capital Weather Gang. Minor flooding associated with king tides is expected to become more common in the District as sea levels rise.
