DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Julia was
located near latitude 12.7 North, longitude 73.1 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.  On 
the forecast track, the center of Julia is expected to move across 
the southwestern Caribbean Sea during the next couple of days, 
passing near San Andres and Providencia Islands Saturday evening, 
and reaching the coast of Nicaragua Sunday morning.  After 
landfall, Julia or its remnants are expected to turn 
west-northwestward and move across Central America through Monday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate 
that maximum sustained winds have increased to near 40 mph (65 
km/h) with higher gusts.  Additional strengthening is forecast, and 
Julia is expected to become a hurricane by Saturday evening before 
it reaches San Andres and Providencia Islands, and the coast of 
Nicaragua.

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

The minimum central pressure is 1002 mb (29.59 inches) based on 
data from the reconnaissance aircraft.

accompanied by large and damaging waves.

of northwestern Venezuela and the Guajira Peninsula of Colombia 
should subside today. Swells are forecast to spread westward and 
reach Jamaica tonight, Providencia and San Andres Islands on
