Coastal Flooding Hazards

RISK LEVEL
HAZARD DESCRIPTION
Low
  • Minor coastal flooding is expected. Minimal property damage is expected, but there is possibly some public threat or inconvenience.
Moderate
  • Moderate coastal flooding is expected, and will result in some inundation of structures and roads near the coast. Some evacuations of people and/or transfer of property to higher elevations may be necessary.
High
  • Major coastal flooding is expected, and will result in extensive inundation of structures and roads near the coast. Significant evacuations of people and/or transfer of property to higher elevations will likely be necessary.

General Information

Coastal flooding is often the result of strong coastal storm systems that bring high winds and seas to coastal areas. Coastal flooding can result from both tropical and non tropical storm systems. The amount of flooding is dependendant on the strength of the winds and the amount of onshore component they have. Strong winds blowing directly onshore for long periods will build the highest water levels and cause the most damage.

Coastal Flood Safety Tips:
  • Coastal flooding can be a very dangerous situation. Know if your location is prone to coastal flooding and the prevailing wind direction that will result in flooding at your location.
  • If water levels begin to rise, be prepared tro evacuate the area immediately. Rising flood waters can cover roadways and cut off your evacuation route, and prevent emergency services personell from reaching you.
  • Do not attempt to drive across flooded roadways. The water may be deeper than it appears, or the road beneath may be washed out. Turn around, don't drown!.

This Outlook is an Experimental Product for Planning purposes Only!!!

The local coastal flood hazard graphics are valid for roughly a 24 hour period from the time of issuance (between 4 AM and 6 AM) until 8 AM the following morning. The highest expected risk possible for the duration of the graphic will be depicted. Only one of the listed criteria needs to be met fo inclusion in a higher risk category

Updates will be posted for significant forecast changes and as time permits. As the weather threat increases throughout the day, or becomes imminent, tornado watches and/or warnings will be issued.

The outlook graphics are an effort to improve the interpretation of our outlooks and statements. This product is provided for emergency managers, law enforcement, schools, local media, businesses, and the public. Use the graphical hazardous weather outlook to factor the threat of hazardous weather into your daily plans.
