DISCUSSION AND OUTLOOK
----------------------
At 200 PM MST (2100 UTC), the center of Tropical Storm Alvin was
located near latitude 18.1 North, longitude 109.0 West. Alvin is
moving toward the north-northwest near 10 mph (17 km/h). A turn 
toward the north is expected tonight, and this motion should 
continue through the weekend.

Maximum sustained winds remain near 50 mph (85 km/h) with higher 
gusts. Weakening is forecast, and Alvin is expected to degenerate to 
a remnant low on Saturday.
 
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
 
The estimated minimum central pressure is 1001 mb (29.56 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF: Swells generated by Alvin will affect portions of the coasts
of west-central and southwestern Mexico and the southern Baja
California Peninsula through the weekend. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
