Dorado, Puerto Rico

... Flash Flood Watch remains in effect through this evening...

The Flash Flood Watch continues for

* all of Puerto Rico and the United States Virgin Islands.

* Through this evening

* a mid to upper level low... just north of Puerto Rico this
morning is producing a large area of cloudiness extending from
Puerto Rico eastward across the northern Leeward Islands and
across the Atlantic for several hundred miles. The abundant
moisture and instability across the region in combination with
the area of low pressure... may provide favorable conditions for
significant convective development today across Puerto Rico...
Vieques... Culebra... and the U.S. Virgin Islands. Heavy rainfall
is possible during the afternoon hours across the central
interior and western Puerto Rico with the addition of daytime
heating and local terrain effects. Mudslides will be likely in
areas of heavy rainfall and steep terrain. For those reasons... a
Flash Flood Watch remains in effect for all of Puerto
Rico... Vieques... Culebra and for the U.S. Virgin Islands through
this evening.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions are favorable for heavy
rain across the watch area... which may lead to flooding. If you are
in the watch area... check your preparedness requirements...
especially if you have interests along area rivers. Keep informed...
and be ready for quick action if flooding is observed or if a Flash
Flood Warning is issued.

People in the watch area should continue to be aware of the
possibility for heavy rainfall. Avoid low lying areas... and be
careful when approaching Highway dips and underpasses. The heavy
rain could also cause mudslides in areas of steep terrain.

Stay tuned to NOAA Weather Radio... local TV... radio or your cable
television provider for later statements and possible warnings.

... High surf advisory remains in effect until 4 PM AST this
afternoon...

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

Large... long period north northeast swells will continue to affect the
Atlantic waters and the Caribbean passages through tonight... peak
during the morning hours... and then slowly subside this afternoon and
evening.

Precautionary/preparedness actions...

These long period swells will continue to produce large breaking
waves of 8 to 12 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 today.
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: 1.6 feet at 4:22 PM this afternoon.

Magens Bay St thomas: 1.3 feet at 4:07 PM this afternoon.

Christiansted St croix: 0.7 feet at 12:03 PM this afternoon.

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.
