DISCUSSION AND OUTLOOK
----------------------
At 1200 AM MDT (0600 UTC), the center of Hurricane Orlene was
located near latitude 18.6 North, longitude 106.8 West.  Orlene is
moving toward the north near 5 mph (7 km/h).  A turn toward the
north-northeast with a slight increase in forward speed is expected
today.  On the forecast track, the center of Orlene should pass 
near or over Las Islas Marias tonight or Monday morning and reach 
the coast of mainland Mexico within the warning area later on Monday 
or Monday night.

Satellite images indicate that the maximum sustained winds have 
increased to near 115 mph (185 km/h) with higher gusts.  Orlene is 
now a category 3 hurricane on the Saffir-Simpson Hurricane Wind 
Scale.  Some additional strengthening is forecast through this 
morning, followed by weakening beginning later today and continuing 
until landfall.

Orlene is a small tropical cyclone. Hurricane-force winds extend
outward up to 10 miles (20 km) from the center and
tropical-storm-force winds extend outward up to 60 miles (95 km).

The estimated minimum central pressure is 962 mb (28.41 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected in Las Islas Marias 
tonight, with tropical storm conditions beginning later today.
Hurricane conditions are expected in the warning area along the
coast of mainland Mexico late Monday, with tropical storm conditions
beginning early Monday.

Tropical storm conditions are expected in the tropical storm warning
area by early today.  Hurricane conditions are possible along the
coast of mainland Mexico within the hurricane watch area by tonight 
or early Monday.  Tropical storm conditions are possible within the 
tropical storm watch area today.

RAINFALL: Into Tuesday, Orlene is expected to produce 3 to 5 inches
of rainfall, with local amounts of 10 inches, across portions of
southwestern Mexico.  These rainfall amounts should 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 along the coast of mainland Mexico in the warning area in
regions of onshore winds.

SURF:  Large swells generated by Orlene are affecting the west coast
of Mexico and will spread northward to the southern portion of the
Baja California peninsula and the Gulf of California through this
weekend. These swells are likely to cause life-threatening surf and
rip current conditions. Please consult products from your local
weather office.
