WEATHER ALERT: Coastal flood warning in effect until Thursday (March 4) morning


A coastal storm, combined with astronomical high tides and a full moon, has resulted in the National Weather Service issuing a coastal flood warning and a hazardous weather outlook for the Bethany Beach area. Minor coastal flooding during Wednesday morning’s high tide may elevate to moderate flooding on during the next high tide into Thursday.

The coastal flood warning is in effect until 6 a.m. Thursday. Minor tidal flooding is expected Wednesday morning along the coastal areas of Delaware and also along the lower Delaware Bay. The high tide Wednesday morning was expected to occur between 9:30 a.m. and 10 a.m. on the ocean and between 10 a.m. and 11:30 a.m. on the Delaware Bay. The high tide in the back bays occurs up to two hours later.

The following high tide, early Wednesday night, will occur with a greater degree of tidal flooding and moderate tidal flooding is now expected. High tide on the oceanfront at Rehoboth Beach is expected to occur at 9:57 p.m. Wednesday evening, with an expected height of 7 to 7.5 feet above mean lower low water.

Those who live in a location that is prone to tidal flooding should be prepared for flooding over the coming days, especially around Wednesday evening’s high tide. Do not park your vehicle in a location that is prone to tidal flooding. Do not drive through flood waters. The water may be deeper than you think it is.

Predicted Bethany Beach “coastal” high tides were expected on Wednesday at 9:46 a.m. and 10:11 p.m., and on Thursday at 10:33 a.m. and 11:01 p.m. Back-bay high tides may occur as much as two hours later than coastal high tides.
