DISCUSSION AND OUTLOOK
----------------------
At 800 AM MST (1500 UTC), the center of Tropical Storm Ileana was
located near latitude 24.9 North, longitude 108.9 West. Ileana is
moving toward the north near 7 mph (11 km/h), and this general
motion is expected to continue today.  A slower motion toward the
north-northwest and northwest is expected tonight and on Sunday.  On
the forecast track, the center of Ileana will move near or over the
coasts of northern Sinaloa and southern Sonora later today, and then
move over the Gulf of California roughly parallel to the coast on
Sunday.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Weakening is forecast to begin later this afternoon or evening, and
Ileana is likely to degenerate into a remnant low tonight.  The
remnant low is expected to dissipate by Monday.
 
Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.
 
The estimated minimum central pressure is 1002 mb (29.59 inches).
