DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Ileana was
located near latitude 16.7 North, longitude 102.7 West.  Ileana is
moving toward the northwest near 17 mph (28 km/h), and a turn toward
the west-northwest is expected on Tuesday, with a continued
west-northwestward track at a reduced forward speed into Wednesday.
On the forecast track, Ileana's center is forecast to move parallel
to and just offshore of the coast of southwestern Mexico through
early Tuesday.

Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts.  Ileana is forecast to strengthen into a hurricane later
today.  Gradual weakening is expected to begin Tuesday night, and
Ileana is forecast to dissipate by Wednesday afternoon or evening
due to its proximity to the much larger Tropical Storm or Hurricane
John located to its southwest.

Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.

The estimated minimum central pressure is 998 mb (29.47 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are possible in the watch area tonight
and early Tuesday.  Tropical storm conditions are expected within
portions of the warning area through early Tuesday.  Tropical storm
conditions are possible within the watch area over southern Baja
California Sur by Tuesday night or early Wednesday.

RAINFALL:  Ileana is expected to produce total rain accumulations
of 2 to 4 inches over coastal sections of the Mexican states of
Guerrero, Michoacan, Colima, and Jalisco, with possible isolated
maximum amounts of 6 inches through Tuesday night.  These rains may
cause flash flooding.

SURF:  Swells generated by Ileana will be affecting portions of
the coast of southwestern Mexico during the next couple of days.
These swells are likely to cause life-threatening surf and rip
current conditions.  Please consult products from your local
weather office.
