* WHAT...Up to one foot of inundation above ground level expected in low-lying areas near shorelines and tidal waterways. * WHERE...Kent and Inland Sussex. * WHEN...From 3 PM this afternoon to 9 PM EDT this evening. * 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.
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.
