When distant storms create high waves near the shore, authorities might issue a high surf advisory or warning.
An advisory means that the waves pose a threat to those on shore. If one is issued, it's best to stay out of the water.
A warning means waves are posing an even greater threat, and it might even mean the waves are already causing damage. If a high surf warning has been issued, you're advised to stay away from the shore.
