When is a Coastal Waters Wind Warning issued?
Warnings for coastal waters are issued whenever strong winds, gale, storm force or hurricane force winds are expected within one or more coastal waters forecast areas.
The initial warning attempts to provide around 24 hours lead-time (sometimes out to 32 hours) and warnings are normally renewed every six hours. If the warning conditions are expected on the following day then it will be mentioned specifically in the warning message.
