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.
