DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Hurricane Julia was located 
near latitude 12.4 North, longitude 84.0 West. Julia is moving 
toward the west near 16 mph (26 km/h). This general motion is 
expected to continue through tonight, followed by a slight turn to 
the west-northwest on Monday. On the forecast track, the center of 
Julia is expected to move across Nicaragua today and emerge over the 
eastern Pacific by tonight. Julia is then forecast to move near or 
along the Pacific coasts of Honduras, El Salvador, and Guatemala on 
Monday and Monday night.

Maximum sustained winds are near 85 mph (140 km/h) with higher 
gusts. Weakening is expected today as Julia moves over Nicaragua, 
but it is still forecast to be a tropical storm when it emerges off 
the Pacific coast of Nicaragua by tonight. Julia is forecast to 
weaken to a tropical depression on Monday night and dissipate by 
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 Bluefields International Airport in Nicaragua recently 
reported a sustained wind of 58 mph (93 km/h). 

The estimated minimum central pressure is 982 mb (29.00 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Julia can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC
and on the web at hurricanes.gov/text/MIATCDAT3.shtml.

WIND:  Hurricane conditions will continue over the coast of
Nicaragua within the warning area this morning. Hurricane conditions
are possible along the coast of Nicaragua within the hurricane watch
area this morning. Tropical storm conditions, mainly in gusts, will
continue for the next few hours on the islands of San Andres,
Providencia, and Santa Catalina.

Tropical storm conditions will continue along the Caribbean coast of
Nicaragua within the tropical storm warning areas through this
morning. Tropical storm conditions are possible along the coast of
Honduras within the watch area through this morning.

Tropical storm conditions are expected along the Pacific coasts of 
Nicaragua, Honduras, and El Salvador within the warning area 
beginning this afternoon into tonight. Tropical storm conditions are 
possible along the Pacific coast of Guatemala within the watch area 
on Monday.

RAINFALL:  Julia is expected to produce the following rainfall
accumulations through early Tuesday:

Nicaragua and El Salvador...5 to 10 inches, isolated 15 inches.
Honduras, Belize, northern Guatemala, and the Isthmus of Tehuantepec
in Mexico...3 to 6 inches, isolated 10 inches.
San Andres, Providencia, and Panama...an additional 2 to 4 inches,
isolated 12 inch storm total amounts.
Southern Guatemala and Costa Rica...4 to 8 inches, isolated 12
inches.

This rainfall may cause life-threatening flash floods and mudslides
across Central America today and Monday. Flash flooding is
anticipated across the Isthmus of Tehuantepec in Mexico early this
week.

STORM SURGE:  A storm surge is likely to raise water levels by as
much as 4 to 6 feet above normal tide levels along the immediate
coast of Nicaragua in areas of onshore winds. Large and damaging
waves will likely accompany the storm surge near the coast.

Water levels should be receding on San Andres, Providencia, and
Santa Catalina Islands as Julia continues moving inland over
Nicaragua.

SURF:  Swells generated by Julia are affecting Jamaica, Providencia,
and San Andres, and the coast of Central America. These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
