a storm surge warning means there is a danger of life-threatening

coastline...during the next 36 hours in the indicated locations.
For a depiction
of areas at risk...please see the national weather service storm
surge watch/warning graphic...available at hurricanes.gov. This is
a
life-threatening situation. Persons located within these areas
should take all necessary actions to protect life and property from
rising water and the potential for other dangerous conditions.
Promptly follow evacuation and other instructions from local
officials.

A storm surge watch means there is a possibility of life-
threatening inundation...from rising water moving inland from the
coastline...in the indicated locations during the next 48 hours.

A hurricane warning means that hurricane conditions are expected
somewhere within the warning area. Preparations to protect life and
property should be rushed to completion.

A hurricane watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds...conditions that make outside preparations difficult or
dangerous.

expected within the warning area within 36 hours.

A tropical storm watch means that tropical storm conditions are
