A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within
the next 6 to 12 hours.

Interests along the coasts of Nicaragua and Honduras should monitor
the progress of the disturbance. Watches or warnings will likely be
required for portions of those coasts later today.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


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.

The estimated minimum central pressure is 1004 mb (29.65 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Depression Thirteen can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.

WIND:  Hurricane conditions are possible on the Colombian islands of
San Andres, Providencia, and Santa Catalina Saturday night into
early Sunday, with tropical storm conditions possible by Saturday
afternoon.

Tropical storm conditions are expected along the coast of Colombia
within the warning area this morning. Gusts to tropical storm force
are possible across portions of the northwestern coast of Venezuela
during the next several hours.

RAINFALL:  The tropical depression is expected to produce the
following rain accumulations through early Monday:

Northern Venezuela, Aruba, Bonaire, and Curacao...additional 1 to 3
inches
Guajira Peninsula...3 to 6 inches, isolated 10 inches.
San Andres and Providencia...6 to 12 inches
Portions of Central America...5 to 10 inches, isolated 15 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 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
products from your local weather office.
