Where
In Delaware, Inland Sussex and Delaware Beaches. In New Jersey, Ocean and Coastal Ocean.
Issued for this forecast zone · National Weather Service Mount Holly NJ
What, impacts and precautionsHide details
What
Up to one half foot of inundation above ground level in low-lying areas near shorelines and tidal waterways.
Impacts
Flooding of lots, parks, and roads with only isolated road closures expected.
Additional details
Water remains trapped in the back bays where we expect minor flooding to continue. Levels are slowly lowering.
Precautionary 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 National Water Prediction Service at https://water.noaa.gov/wfo/phi for additional water level and flood impact information for your local tide gauge.
