DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Tropical Storm Julia was 
located near latitude 12.7 North, longitude 77.2 West. Julia is 
moving toward the west near 18 mph (30 km/h). This general motion 
should continue through tonight, with a westward motion at a slower 
forward speed expected on Sunday and Sunday night. On the forecast 
track, the center of Julia is expected to pass near or over San 
Andres and Providencia Islands this evening and then reach the coast 
of Nicaragua on Sunday morning. Julia or its remnants will then turn 
west-northwestward over Central America by Monday.

Air Force Reserve Hurricane Hunter aircraft data indicate that 
maximum sustained winds have increased to near 60 mph (95 km/h) with 
higher gusts. Steady to possibly rapid strengthening is forecast 
while Julia moves across the southwestern Caribbean Sea during the 
next day or so, 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 105 miles (165 km),
mainly to the northeast of the center.

The minimum central pressure based on the Hurricane Hunter aircraft
data is 999 mb (29.50 inches).
