DISCUSSION AND OUTLOOK
----------------------
At 300 PM MDT (2100 UTC), the center of Tropical Storm Lorena was
located near latitude 21.6 North, longitude 107.0 West. Lorena is
moving toward the northwest near 13 mph (20 km/h).  A turn to the
west-northwest is expected tonight, and a west-northwestward motion
at a slower forward speed should continue through Saturday.  On the
forecast track, the center of Lorena will move over the Pacific
waters to the southeast of the Baja California peninsula tonight,
pass near or over the southern portion of the Baja California
peninsula on Friday, and move along the west coast of the peninsula
Friday night 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 as it approaches
the Baja California peninsula.

Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.  A Mexican navy automated station on Isla Maria
Madre island recently reported sustained winds of 45 mph (73 km/h)
and a wind gust of 65 mph (105 km/h).

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

Far southern Baja California Sur: 2 to 4 inches with maximum
amounts around 6 inches.
