DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Depression Thirteen
was located near latitude 12.3 North, longitude 71.9 West.  The
depression is moving toward the west near 15 mph (24 km/h), and a
generally westward motion is expected to continue through Sunday. On
the forecast track, the cyclone is expected to move over the
southwestern Caribbean Sea today through Saturday. The system is 
forecast to pass near San Andres and Providencia Islands Saturday 
night, and approach the coast of Nicaragua on Sunday morning.
 
Maximum sustained winds are near 35 mph (55 km/h) with higher
gusts. Gradual strengthening is forecast today, and the depression
is expected to become a tropical storm later this morning or this
afternoon. A faster rate of strengthening is forecast on Saturday
and Saturday night, and the system is expected to become a hurricane
before it reaches San Andres and Providencia Islands and the coast
of Nicaragua this weekend.

Tropical storm conditions are expected along the coast of Colombia
within the warning area this morning. Gusts to tropical storm force

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 the cyclone are affecting the ABC Islands
and portions of the coasts of northwestern Venezuela and the Guajira
Peninsula of Colombia. These swells are forecast to spread westward
and reach Jamaica late tonight, Providencia and San Andres Islands
on Saturday, and portions of the coast of Central America on
Saturday night and Sunday. These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
