Interests along the coasts of Nicaragua and Honduras should monitor
the progress of the disturbance.  Additional watches or warnings
could be required tonight or on Friday.

southwestern Caribbean Sea, moving near San Andres and Providencia
Islands Saturday night, and approaching the coast of Nicaragua on
Sunday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Strengthening is forecast during the next few days.  The system 
is expected to become a tropical depression or tropical storm by

HAZARDS AFFECTING LAND

San Andres, Providencia, and Santa Catalina Saturday night, with
tropical storm conditions possible by Saturday afternoon.

Tropical storm conditions are expected along the coast of Colombia 
within the warning area by early Friday.  Gusts to tropical
storm force are also possible across the ABC Islands and the
northwestern coast of Venezuela today and tonight.

RAINFALL:  Potential Tropical Cyclone Thirteen is expected to
produce the following rain accumulations through early Monday:

Northern Coastal Venezuela...3 to 6 inches, isolated 10 inches.
Aruba, Bonaire, and Curacao...3 to 6 inches
Guajira Peninsula...3 to 6 inches, isolated 10 inches.

This rainfall may cause life-threatening flash floods.  There is
also the potential for life-threatening mudslides across portions of
Central America this weekend.

STORM SURGE:  A storm surge could raise water levels by as much as
1 to 3 feet above normal tide levels along the immediate coast in
areas of onshore winds on San Andres, Providencia, and Santa
Catalina Islands.  Near the coast, the surge will be accompanied by
large and damaging waves.

SURF:  Swells generated by disturbance will affect the ABC Islands
and portions of the coasts of northwestern Venezuela and the Guajira
Peninsula of Colombia through Friday.  Swells could reach Jamaica,
Providencia, and San Andres on Saturday, and portions of the coast
of Central America on Sunday.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
