hours.  Preparations to protect life and property should be rushed
to completion.

A Hurricane Watch means that hurricane conditions are possible
within the watch area.  A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere in Baja California Sur should monitor the
progress of Lorena.  Additional watches or warnings may be required
for portions of this area later today.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 300 AM MDT (0900 UTC), the center of Tropical Storm Lorena was
located near latitude 22.3 North, longitude 108.5 West. Lorena is
moving toward the west-northwest near 9 mph (15 km/h). A turn
toward the northwest is expected on Saturday.  On the forecast
track, the center of Lorena will pass near or over the southern
portion of the Baja California peninsula later today and then
gradually move away from the west coast of the peninsula tonight and
Saturday.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts.  Strengthening is forecast during the next day or so, and
Lorena is forecast to re-gain hurricane strength today as it
approaches the Baja California peninsula.  Lorena is likely to begin
weakening by Saturday night, and then either degenerate into a
remnant low, or become absorbed by Tropical Storm Mario in
a few days.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure is 994 mb (29.36 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Lorena can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC
and on the web at www.hurricanes.gov/text/MIATCDEP5.shtml.

WIND:  Hurricane conditions are expected within the hurricane
warning area in the southern Baja California peninsula later today,
with tropical storm conditions beginning by this morning.
Hurricane and tropical storm conditions are possible within the
hurricane watch area by Saturday.  Tropical storm conditions are
possible in the tropical storm watch area by Saturday night.

RAINFALL:  Lorena is expected to produce rainfall accumulations of 3
to 6 inches, with maximum amounts around 8 inches, across the far
southern Baja California Sur. This rainfall may result in flash
flooding.

SURF:  Swells generated by Lorena will affect portions of the
southwestern coast of Mexico and the southern Baja California
peninsula 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.
