Toa Baja, 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 swells will continue to slowly build
across the Atlantic waters and the Caribbean passages
today... while peaking Wednesday morning and then slowly
subsiding Wednesday afternoon and evening.

Precautionary/preparedness actions...

These long period swells will 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 today through 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: 1.8 feet at 3:34 PM today
                 1.4 feet at 4:08 am Wednesday and
                 1.6 feet at 4:22 PM Wednesday afternoon.

Magens Bay St thomas: 1.0 feet at 3:49 PM this afternoon and
                      0.6 feet at 5:13 am Wednesday

Christiansted St croix: 0.9 feet at 12:59 PM today and 0.7 feet at
                        12:03 PM Wednesday.
