# DETAILS
--------------------
WHAT
Up to one half foot of inundation above ground level in low-lying areas near shorelines and tidal waterways.
WHERE
In Delaware, Inland Sussex and Delaware Beaches. In New Jersey, Ocean and Coastal Ocean.
WHEN
Until midnight EDT tonight.
IMPACTS
At this level, flooding begins on the most vulnerable roads in coastal and bayside communities, and along inland tidal waterways. Some partial or full road closures are possible.
ADDITIONAL DETAILS
Along the oceanfront areas in these counties, minor tidal flooding looks to be spotty this evening. However water remains trapped in the back bays where we expect more widespread minor flooding to continue. In fact it's possible minor flooding will continue to be an issue through Saturday for these back bay areas.

Coastal Hazard Message
# 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 National Water Prediction Service at https://water.noaa.gov/wfo/phi for additional water level and flood impact information for your local tide gauge.
