DISCUSSION AND OUTLOOK
----------------------
At 1200 PM MDT (1800 UTC), the center of Hurricane Orlene was
located near latitude 19.9 North, longitude 106.9 West. Orlene is
moving toward the north near 8 mph (13 km/h).  A turn toward the
north-northeast is expected later 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.

Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts.  Orlene is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Weakening is expected during the next day or
so, however Orlene is forecast to be a strong hurricane when it
passes near or over the Islas Marias, and remain a hurricane when it
reaches southwestern Mexico.

Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 70
miles (110 km).

The latest minimum central pressure estimated from Air Force 
Reserve reconnaissance aircraft data is 972 mb (28.70 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 to spread northward in the
tropical storm warning area today through early Monday.  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: Orlene is expected to produce the following rainfall
across portions of Southwest Mexico through Tuesday:

* Islas Marias: 6 to 10 inches, with local amounts of 14 inches.
* Nayarit and Sinaloa: 3 to 6 inches with local amounts of 10
inches.
* Jalisco and Colima: 1 to 3 inches with local amounts of 5 inches.

These rainfall amounts will likely 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 over the next
couple of days. These swells are likely to cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
