Isabela, Puerto Rico

... High surf advisory remains in effect until 4 PM AST Wednesday...

A high surf advisory remains in effect until 4 PM AST Wednesday.

Large... long period north northeast swells will continue to slowly
build across the Atlantic waters and the Caribbean passages through
tonight... peak Wednesday morning... and then slowly subside
Wednesday afternoon and evening.

Precautionary/preparedness actions...

These long period swells will continue to produce large breaking
waves of 10 to 16 feet and locally higher... along the local reefs...
beaches and Shoals of the northwest through northeast coasts of all
of the local islands through late Wednesday. Therefore... a high surf
advisory remains in effect.

These breaking waves will generate strong and dangerous currents
within the surf zone... called rip currents. These narrow outward
flowing currents can carry people and animals away from the coast
line and out to sea. If you become caught in a rip current... do not
panic. Calmly... remain afloat... gather your bearings relative to the
beach... and swim parallel to the beach. You will eventually leave
the grip of this narrow current... and be able to safely swim to
shore.

Local beach goers... and inexperienced surfers and swimmers should
stay out of the water until these hazardous surf conditions subside.
Persons on the beach should be vigilant for large breaking waves
surging upon the shore... which can carry people of all sizes into
the ocean. You should avoid being near the shore line and stay off
of rock formations.

These surging waves will also create the potential for beach erosion
during times of high tide.

The times of the next high tides for the following locations are:

San Juan harbor: 1.4 feet at 4:08 am Wednesday
                 1.6 feet at 4:22 PM Wednesday afternoon.

Magens Bay St thomas: 1.0 feet at 5:07 am Wednesday

Christiansted St croix: 0.7 feet at 12:03 PM Wednesday.

Please stay tuned to NOAA all hazards radio for the latest
information on this dangerous marine situation from your National
Weather Service forecast office in San Juan.
