DISCUSSION AND OUTLOOK
----------------------
At 300 PM MDT (2100 UTC), the center of Hurricane Orlene was located
near latitude 17.9 North, longitude 107.1 West. Orlene is moving
toward the north near 5 mph (7 km/h). A north-northeastward motion
at a slightly faster speed is expected to begin by tonight and
continue through early next week. On the forecast track, the
center of Orlene should pass near or over Las Islas Marias Sunday
night or Monday morning and reach the coast of mainland Mexico later
on Monday or Monday night.

Reports from an Air Force Reserve Hurricane Hunter aircraft
indicate that maximum sustained winds have increased to near 80 mph
(130 km/h) with higher gusts. Additional strengthening is forecast
through Sunday afternoon.  Steady to rapid weakening is expected
starting Sunday night and continuing until landfall.

Aircraft and satellite wind data indicate that Orlene remains 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 45 miles (75 km).

The minimum central pressure reported by the Hurricane Hunter
aircraft is 979 mb (28.91 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are expected in Las Islas Marias Sunday 
night, with tropical storm conditions beginning late Sunday. 
Tropical storm conditions are expected in the tropical storm warning 
area by early Sunday. Hurricane conditions are possible along the 
coast of mainland Mexico within the hurricane watch area by Sunday 
night into Monday. Tropical storm conditions are possible along the 
coast of mainland Mexico within the tropical storm watch area 
tonight and Sunday.

RAINFALL: Into Monday evening, Orlene is expected to produce 3 to 5
inches of rainfall, with local amounts of 10 inches, for portions of
southwest Mexico.  These rainfall amounts should lead to flash
flooding, as well as possible landslides in areas of rugged terrain.

STORM SURGE: Coastal flooding is likely along the coast of Mexico
in the warning area in regions of onshore winds.

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