DISCUSSION AND OUTLOOK
----------------------
At 900 PM MDT (0300 UTC), the center of Tropical Storm Lorena was
located near latitude 27.6 North, longitude 111.2 West. Lorena is
moving toward the north near 12 mph (19 km/h), and this general
motion is expected to continue during the next 24 hours or so. On
the forecast track, the center of Lorena is expected to cross the
coast of mainland Mexico during the next several hours, followed by
a motion across northwestern Mexico.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is likely before landfall.  After
landfall, Lorena is expected to weaken, and the system is forecast
to dissipate over northwestern Mexico by Monday morning.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.

The estimated minimum central pressure is 1002 mb (29.59 inches).

next several hours.

RAINFALL:  Rainfall: Lorena is expected to produce total rain
accumulations of 3 to 6 inches over central Sonora, and additional
rainfall of less than one inch over Baja California Sur through
Sunday. This rainfall may result in life-threatening flash floods
in Sonora.

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