Description:
A High Surf Warning is issued when waves reach threshold criteria for a particular island and shoreline. High Surf Warnings may be issued up to 24 hours ahead of the arrival of the swell and may remain in effect for several days.
Instruction:
Large breaking surf, significant shorebreak, and dangerous
currents make entering the water very hazardous. Anyone entering
the water could face significant injury or death. Surf events of
this caliber also have the ability to cause coastal overwash and
significant impacts to shorelines, especially those already
susceptible to erosion. Greatest impacts will coincide with the
high tide occurring early Sunday morning.
