NOTE:
Please refer to our
Coastal Hazard Message
for specific information regarding Coastal Flood Watches, Warnings and Advisories. Actual impacts from any coastal flooding event may vary due to factors such as rainfall, wave action, and the number of tide cycles during which there is an onshore flow. During tropical cyclones, please refer
here
for additional storm surge information.
NOTE:
During a Tropical Storm or Hurricane Watch or Warning, inundation mapping provided by the
National Hurricane Center
(go to the web site and select the storm of interest) reflects a plausible worst case scenario. The forecast above is the total water forecast that is most likely to occur.
NOTE:
Forecasts for the Atlantic Coast at Watch Hill Cove (IN MLLW) are issued routinely year-round.
