National Weather Service map shows levels of flooding expected along the coast.

Moderate coastal flooding is expected for the high tide cycles on Thursday evening, Friday morning, and Friday evening at the Jersey Shore, according to the latest forecast by the National Weather Service.

Flooding is possible through five consecutive high tide cycles dating back to Wednesday evening. Water will not be allowed to drain from many of the back bays and estuaries. As a result, the cumulative impacts may be significant.

Gale force winds of 35 to 40 knots are expected on the Atlantic coastal waters of New Jersey and Delaware, and on the lower Delaware Bay through early Saturday, according to the forecast.

Wind gusts in the coastal counties of New Jersey and Delaware could reach 30 to 40 mph at times through Friday night.

The prolonged nature of the unsettled weather will result in significant beach erosion, the National Weather Service says.
