WEATHER ALERT: Coastal flood advisory/watch through Thursday afternoon; Rip currents likely


The National Weather Service in Mount Holly, N.J., has issued a coastal flood advisory for the Delaware beaches. The coastal flood advisory remains in effect until 4 p.m. EDT this afternoon. A coastal flood watch in effect from Thursday morning through Thursday afternoon, with a high risk of rip currents today.

According to the NWS, a northeast flow will increase today and tonight and continue into Thursday as low pressure approaches slowly from the south. Higher-than-normal water levels will result from this onshore flow.

For today, this may cause minor tidal flooding from late morning into early this afternoon. High tide was to occur between 10 a.m. and noon, and the back bays usually reach high tide 1 or 2 hours later. Also, a high risk of rip currents will be in effect for today.

On Thursday, the persistent northeast winds will cause more piling of water onto the shore. Along with heavy rain and strong wave action, this may result in areas of moderate tidal flooding later Thursday morning and early Thursday afternoon.

At Rehoboth Beach, high tide will occur at 12:21 p.m., with a forecast tide level of near 7.5 feet above mean lower low water. High tide occurs later on the back bays.

A coastal flood advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore.

Do not park your car in an area that receives tidal flooding.

A coastal flood watch means that conditions favorable for flooding are expected to develop. Coastal residents should be alert for later statements or warnings and take action to protect property.
