DISCUSSION AND OUTLOOK
----------------------
At 500 AM MST (1200 UTC), the center of Hurricane Polo was located
near latitude 26.9 North, longitude 111.7 West. Polo is moving
toward the northeast near 10 mph (17 km/h) and this motion is

Gulf of California for the next several hours, then move inland 
over southern Sonora late this morning.
 
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Little change in strength is expected before Polo makes its 
second landfall in mainland Mexico. Rapid weakening is forecast 
later today when Polo moves well inland over mainland Mexico.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).
 
The estimated minimum central pressure is 981 mb (28.97 inches).
