DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Hurricane Julia was located 
near latitude 12.5 North, longitude 83.3 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 within the warning area on the coast of 
Nicaragua shortly, then move across Nicaragua later today. Julia is 
forecast to move near or along the Pacific coasts of Honduras, El 
Salvador, and Guatemala on Monday and Monday night.

Satellite intensity estimates indicate that maximum sustained winds 
have increased to near 85 mph (140 km/h) with higher gusts. 
Strengthening is possible 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 today or tonight. Julia is forecast to 
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 estimated minimum central pressure is 982 mb (29.00 inches).
