flooding possible as a result of increased wave run-up.
* IMPACTS...Large breaking waves along the coast will lead to
increased wave run-up on beaches with waves topping and washing
over large rocks and jetties. Use extra caution near the surf
zone as these large waves will be capable of sweeping people
into the frigid and turbulent ocean water. Cold water shock may
cause cardiac arrest, and it also can cause an involuntary gasp
reflex causing drowning, even for a good swimmer. Long periods
increases the risk of rip currents. The surf zone will be
dangerous due to strong currents and powerful breaking waves.

Information:

the advisory area, producing rip currents, localized beach
erosion and sneaker waves.
