Coastal Flood Advisory
Issued: 11:37 AM EST Jan. 19, 2019 – National Weather Service

... Coastal flood advisory in effect from 5 am to 11 am EST
Sunday...

The National Weather Service in Mount Holly has issued a coastal
flood advisory, which is in effect from 5 am to 11 am EST Sunday.

* Locations... coastal areas of southern New Jersey and Delaware,
including adjacent portions of the Delaware Bay coast in Cape
May and Sussex counties.

* Timing... flooding will occur for a few hours around the time of
high tide Sunday morning. High tide on the New Jersey and
Delaware oceanfront is between 6:00 am and 7:00 am. High tide on
the back bays and along 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. 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. Minor roadway
flooding is possible in Atlantic City, Absecon, and Ventnor. 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. Rainfall may exacerbate tidal
levels, leading to more significant impacts.

* Waves... wave heights on the ocean waters off the coast are
forecast to be 5 to 9 feet. Wave heights on Delaware Bay are
forecast to be 2 to 5 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.


Time of high total tides are approximate to the nearest hour.
