DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Julia was
located near latitude 12.6 North, longitude 81.3 West. Julia is
moving toward the west near 17 mph (28 km/h). A continued westward
motion with some decrease in forward speed is expected during the
next couple of days. On the forecast track, the center of Julia is
expected to reach the coast of Nicaragua overnight, move across
Nicaragua on Sunday, and then move near or along the Pacific coasts
of Honduras, El Salvador, and Guatemala through Monday.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Some additional strengthening is forecast this evening and
tonight, and Julia could become a hurricane while passing near San
Andres and Providencia Islands this evening. Julia is also
expected to be a hurricane when it reaches the coast of Nicaragua
overnight. Weakening is expected once Julia moves inland, but it is
forecast to still be a tropical storm when it moves off the Pacific
coast of Nicaragua late Sunday. Julia should weaken to a tropical
depression on Monday and dissipate by Monday night.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
from the center.

The estimated minimum central pressure is 992 mb (29.30 inches).
