DISCUSSION AND OUTLOOK
----------------------
At 200 PM EDT (1800 UTC), the center of Tropical Storm Julia was
located near latitude 12.9 North, longitude 73.9 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.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. 
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 an Air Force Reserve reconnaissance aircraft.
