Coastal Flooding Impacts Definitions
Read this office's detailed Hurricane Local Statement

None Threat - No discernable threat to life and property; no surge waters expected.

Minimum Action - Evaluate personal and community disaster plans and ensure seasonal preparedness activities are complete.

Potential Impact - Coastal flooding is not expected; impact should be negligible. Surf conditions may still be rough with minor beach erosion.

Low Threat - An elevated threat to life and property; the likelihood for storm surge and storm tide waters of 2.8 to 4 feet.

Minimum Action - Prepare for the likelihood of minor storm surge damage.

Potential Impact - A low impact to communities in the specified area. Coastal flood waters capable of causing moderate to locally major beach erosion. Very heavy surf breaching dunes in isolated locations, mainly in historically vulnerable spots.

Moderate Threat - A significant threat to life and property; the likelihood for storm surge and storm tide waters of 4 to 6 feet.

Minimum Action - Prepare for the likelihood of moderate storm surge damage.

Potential Impact - A moderate impact to communities in the specified area. Coastal flood waters capable of causing major beach erosion. A few sections of near-shore escape roads weakened or washed out, especially in historically vulnerable low spots. Surge waters and wind waves breaching dunes and seawalls in scattered locations to result in structural damage to a few shoreline buildings, mainly in historically vulnerable spots. Minor damage to marinas, docks, and piers. A few small craft broken away from moorings, especially in unprotected anchorages.

High Threat - A critical threat to life and property; the likelihood for storm surge and storm tide waters of 6 to 8 feet.

Minimum Action - Prepare for the likelihood of major storm surge damage.

Potential Impact - A high impact to communities in the specified area. Coastal flood waters capable of causing partial inundation of the surge zone by sea water, especially for low-lying areas. Severe beach erosion. Several sections of near-shore roads washed out and/or low-lying escape roads flooded. Scouring surge waters and battering wind waves breaching dunes and seawalls in scattered locations to result in structural damage to several shoreline buildings, with a few washing into the sea. Damage accentuated by floating debris. Damage to marinas, docks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages.

Extreme Threat - An extreme threat to life and property; the likelihood for storm surge and storm tide waters greater than 8 feet.

Minimum Action - Prepare for the likelihood of extreme to catastrophic coastal flood damage.

Potential Impact - An extreme impact to communities in the specified area. Coastal flooding capable of causing widespread inundation of the surge zone by sea water, possibly reaching several miles inland for low-lying areas. Extreme beach erosion with several new inland cuts likely created. Many large sections of near-shore roads washed out and/or low-lying escape routes roads flooded. Powerful scouring surge waters and intense battering wind waves breaching dunes and seawalls in widespread locations to result in structural damage to numerous shoreline buildings, with several washing into the sea. Damage accentuated from considerable floating debris. Extensive damage to marinas, docks, and piers. Numerous small craft broken away from moorings.

Note: In all cases, listen to local authorities and obey any evacuation orders for your coastal area. Remember, increasing wind and rising waters can cut off escape routes well in advance of landfall.
