... High surf advisory remains in effect from 6 p.m. this evening to 6 a.m. EST Friday...

Coastal flood watch remains in effect from late tonight through late Thursday night...

A high surf advisory remains in effect from 6 p.m. this evening until 6 a.m. on Friday. A coastal flood watch remains in effect from late tonight through late Thursday night.

With high pressure to the north and low pressure remaining to the south, a strong and persistent northeast flow is expected along the coasts of New Jersey and Delaware into the weekend. As a result, tidal departures will increase. Minor tidal flooding is likely beginning late tonight and moderate tidal flooding is possible by week’s end.

On Thursday and Friday, high tide on the New Jersey and Delaware oceanfront occurs in the early morning hours, between 3 a.m. and 5 a.m., and in the late afternoon, between 3:15 p.m. and 5:15 p.m. High tide on the back bays and along the Delaware Bay occurs a little later than it does on the oceanfront.

Minor tidal flooding is expected for the high tide cycles early on Thursday morning and late on Thursday afternoon. However, as tidal departures increase some moderate tidal flooding is possible during the high tide early on Friday morning. At that time, tide levels may reach or exceed 7.0 feet mllw at Atlantic City, N.J., and at Lewes, Del. Tide levels may reach or exceed 7.7 feet mllw at Cape May, N.J.

The potential for tidal flooding will continue into the early part of the weekend.

Also, waves off the coasts of New Jersey and Delaware are forecast to build to around 15 feet or higher from tonight into the early part of the weekend. As a result, breakers along the coast may approach 7 or 8 feet, with a good deal of beach erosion anticipated. A high surf advisory has been issued.

Precautionary/preparedness actions…

A coastal flood watch means that conditions are favorable for the development of flooding. Pay close attention to statements, advisories and warnings, and take action, if necessary.

Do not park your vehicle in a location that is prone to tidal flooding. Also, avoid roadways that are prone to tidal flooding.

A high surf advisory means that high surf will affect area beaches, producing rip currents and beach erosion.
