DISCUSSION AND OUTLOOK
----------------------
At 1200 AM MDT (0600 UTC), the center of Tropical Storm Orlene was 
located near latitude 17.1 North, longitude 107.2 West. Orlene is 
moving toward the north near 5 mph (7 km/h).  Orlene is forecast to 
have a slight increase in forward speed later this morning and turn 
toward the north-northeast by tonight. This north-northeastward 
motion is expected to continue into early next week. 
 
Maximum sustained winds are near 65 mph (100 km/h) with higher
gusts.  Steady to rapid strengthening is expected through tonight, 
and Orlene is forecast to become a hurricane later today.
 
Orlene remains a small tropical cyclone.  Tropical-storm-force
winds extend outward up to 45 miles (75 km) from the center.
 
The estimated minimum central pressure is 994 mb (29.36 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Hurricane conditions are possible in Las Islas Marias on
Sunday, with tropical storm conditions possible tonight and
Sunday.  Tropical storm conditions are expected in the warning area
by early Sunday. 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
southwestern 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.
