DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Julia was located 
near latitude 12.5 North, longitude 82.0 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 75 mph (120 km/h) with higher
gusts.  Strengthening is forecast until landfall in Nicaragua. 
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.

Hurricane-force winds extend outward up to 30 miles (50 km) from 
the center, while tropical-storm-force winds extend outward up to 
115 miles (185 km) from the center.

The minimum central pressure estimated from NOAA Hurricane Hunter 
aircraft data is 989 mb (29.20 inches).
