DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the disturbance was centered near
latitude 12.0 North, longitude 74.0 West. The system is moving
toward the west near 20 mph (31 km/h), and a continued mostly
westward motion with a decrease in forward speed is expected
through Saturday. On the forecast track, the system will move
across the southwestern Caribbean Sea today through Friday, cross
southern Nicaragua or northern Costa Rica Friday night, and emerge
over the eastern Pacific Ocean on Saturday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Some strengthening is forecast through Friday while the system
approaches Central America. Weakening is expected while the system
crosses Central America, but restrengthening is forecast on
Saturday once it moves over the Pacific Ocean.

Conditions appear conducive for development, and the disturbance is
expected become a tropical storm while slowing down over the
southwestern Caribbean Sea.
* Formation chance through 48 hours... high...90 percent.
* Formation chance through 5 days...high...90 percent.

Tropical-storm-force winds extend outward up to 80 miles (130 km)
from the center.

The estimated minimum central pressure is 1008 mb (29.77 inches).
