DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Tropical Storm Lorena was
located near latitude 17.6 North, longitude 104.0 West. Lorena is
moving toward the northwest near 13 mph (20 km/h). A slower
northwestward motion is expected during the next couple of days. On
the forecast track, Lorena is expected to move near or over the
southwestern coast of Mexico within the hurricane warning area
tonight and Thursday. The center of Lorena is then expected to move
west-northwestward away from the western coast of Mexico late
Thursday and Friday and approach southern Baja California Friday
night and Saturday.

Maximum sustained winds have increased to near 70 mph (110 km/h)
with higher gusts. Additional strengthening is forecast during the
next 24 hours, and Lorena is expected to become a hurricane as it
nears the coast of southwestern Mexico.

Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.

The estimated minimum central pressure is 993 mb (29.32 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected within the hurricane
warning area as early as this evening, and then will spread
northwestward tonight and Thursday. Tropical Storm conditions will
first reach the coast within the hurricane warning area later today.
Preparations to protect life and property should be rushed to
completion.

Tropical storm conditions are expected within the southern
portion of the tropical storm warning area later today, and then
are expected to spread northward along the coast through
Thursday night.

RAINFALL:  Lorena is expected to produce total rainfall
accumulations of 5 to 10 inches with maximum amounts of 15 inches
along the coastal sections of the Mexican states of Guerrero,
Michoacan, Colima and Jalisco.  This rainfall may produce life-
threatening flash floods and mudslides.

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