DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Julia was
located near latitude 12.8 North, longitude 76.1 West. Julia is
moving toward the west near 17 mph (28 km/h).  This general motion 
should continue through Saturday night, with a westward motion at 
at a slower forward speed expected Sunday and 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.
 
Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft 
indicate that maximum sustained winds are near 45 mph (75 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 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 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).
