501 PM EDT Thu Mar 21 2019

...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 1 AM EDT
FRIDAY...

* LOCATIONS...Coastal areas of Cape May County and Cumberland
  County in New Jersey, and Sussex County and Kent County in
  Delaware.

* TIMING...High tide on the New Jersey oceanfront occurs between
  8:30 and 9:30 PM Thursday. High tide on the back bays and on
  Delaware Bay occurs later than the high tide on the oceanfront.

* COASTAL FLOOD IMPACTS...Up to one foot of saltwater inundation
  above ground level is possible in low-lying areas near
  shorelines and tidal waterways. Minor roadway flooding is
  possible in Fortescue, Money Island, Gandys Beach and other
  locations near the Delaware Bay shoreline. In Sussex County
  Delaware, roadway flooding is possible in Fenwick Island,
  Dewey Beach, Bethany Beach, Lewes, Rehoboth Beach, and other
  locations along the ocean, the bay, and tidal tributaries. In
  Kent County Delaware, roadway flooding is possible in Woodland
  Beach, Bowers Beach, Kitts Hummock, and other locations along
  the bay and its tidal tributaries. In Cape May County, minor
  roadway flooding is possible in Wildwood, Cape May, Avalon,
  and other locations along the shore and the Delaware Bay
  shoreline.

* WAVES...Wave heights on the ocean waters off the coast are
  forecast to be 5 to 7 feet. Wave heights on Delaware Bay
  should by up to 3 to 4 feet.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Coastal Flood Advisory means that minor tidal flooding is
expected. Minor tidal flooding often results in some road
closures. Usually, the most vulnerable roadways will flood.

Do not leave your vehicle at a location that is prone to tidal
flooding. Do not drive your vehicle through flood waters. The
water may be deeper than you think it is. You will be putting
yourself in danger and your vehicle may be damaged, leading to
costly repairs.

Visit the Advanced Hydrologic Prediction Service at
water.weather.gov/ahps for additional water level and flood
impact information for your local tide gauge.
