DISCUSSION AND OUTLOOK
----------------------
At 600 AM MDT (1200 UTC), the center of Hurricane Orlene was located
near latitude 22.6 North, longitude 106.1 West. Orlene is moving
toward the north near 9 mph (15 km/h), and a general northward to
north-northeastward motion is expected to continue over the next day
or so.  On the forecast track, the center of Orlene will reach the 
coast of mainland Mexico within the warning area this morning. 

Maximum sustained winds are near 100 mph (155 km/h) with higher 
gusts. Little change in strength is expected before Orlene reaches
the coast.  Rapid weakening is forecast after Orlene moves
onshore, and the system should dissipate tonight or Tuesday.
 
Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).
 
The estimated minimum central pressure is 976 mb (28.82 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane and tropical storm conditions are expected in the 
warning areas along the coast of mainland Mexico today.
 
Hurricane conditions are possible along the coast of mainland 
Mexico within the hurricane watch area this morning.
 
RAINFALL: Orlene is expected to produce the following rainfall
across portions of southwestern Mexico through Tuesday:
 
* Islas Marias: 6 to 10 inches, with local amounts of 14 inches.
* Nayarit and southern Sinaloa: 3 to 6 inches with local amounts of
10 inches.
* Jalisco, Colima, and southwest Durango: 1 to 3 inches with local
amounts of 5 inches.
 
These rainfall amounts are likely to lead to flash flooding, as
well as possible landslides in areas of rugged terrain.
 
STORM SURGE: A dangerous storm surge is likely to cause coastal
flooding in the Islas Marias and along the coast of mainland Mexico
in the warning area in regions of onshore winds.
 
SURF:  Large swells generated by Orlene will affect the 
southwestern coast of Mexico, southern portions of the Baja 
California peninsula and the Gulf of California over the next day 
or so. These swells are likely to cause life-threatening surf
and rip current conditions.  Please consult products from your local
weather office.
