DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Julia was
located near latitude 13.0 North, longitude 74.7 West.  Julia is
moving toward the west near 18 mph (30 km/h).  A westward motion 
with some decrease in forward speed is expected through Sunday 
night.  On the forecast track, the center of Julia is expected to 
pass near or over San Andres and Providencia Islands Saturday 
evening and then reach the coast of Nicaragua Sunday morning.  
Julia or its remnants will then turn west-northwestward over 
Central America by Monday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Strengthening is forecast while Julia moves across the southwestern 
Caribbean Sea during the next day or two, and the system is 
expected to become a hurricane by the time it passes near or over 
San Andres and Providencia Islands and reaches the coast of 
Nicaragua.  Quick weakening is anticipated after Julia moves inland 
on Sunday, and it is likely to become a remnant low or dissipate by 
Monday.

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

The estimated minimum central pressure is 1002 mb (29.59 inches).
