DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Patricia was
located near latitude 13.0 North, longitude 98.2 West. Patricia is
moving toward the west near 12 mph (19 km/h) and this motion is
likely to continue today.  A turn toward the west-northwest is
expected tonight, with a turn toward the northwest expected on
Thursday.  On the forecast track, the center of Patricia should
approach the coast of southwestern Mexico on Friday.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Strengthening is forecast during the next 48 hours, and Patricia is
expected to become a hurricane Thursday or Thursday night.  A NOAA
Hurricane Hunter Aircraft is currently enroute to investigate
Patricia.

Tropical storm force winds extend outward up to 140 miles (220 km)
from the center.

The estimated minimum central pressure is 1004 mb (29.65 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are possible within the hurricane watch
area by early Friday.  Tropical storm conditions are possible within
the watch areas by late Thursday or early Friday.

RAINFALL:  Patricia is expected to produce total rainfall
accumulations of 6 to 12 inches, with isolated maximum amounts of 20
inches, over the Mexican states of Jalisco, Colima, Michoacan and
Guerrero later Thursday into Saturday.  These rains could produce
life-threatening flash floods and mud slides.
