DISCUSSION AND OUTLOOK
----------------------
At 1100 PM EDT (0300 UTC), the center of Hurricane Julia was located
near latitude 12.5 North, longitude 82.7 West. Julia is moving
toward the west near 16 mph (26 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 make landfall on the coast of Nicaragua during the 
next several hours, move across Nicaragua on Sunday, and then move 
near or along the Pacific coasts of Honduras, El Salvador, and 
Guatemala through Monday and Monday night.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Strengthening is expected until the center makes 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 or Sunday night.  Julia 
should weaken to a tropical depression on Monday and dissipate by 
Monday night or Tuesday.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km).

The minimum central pressure estimated from NOAA Hurricane Hunter 
aircraft data is 988 mb (29.18 inches).

STORM SURGE:  A storm surge is likely to raise water levels by as
much as 2 to 4 feet above normal tide levels along the immediate
