large waves will be capable of sweeping people into the frigid
and turbulent ocean water. Mariners traversing The Bar are urged
to exercise extreme caution or stay in port until the threat

Precautionary/preparedness actions...

A high surf warning indicates that dangerous, battering waves
will pound the shoreline resulting in beach erosion. Stay far
back from the surf and do not enter areas flooded by the waves.
