DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Hurricane Rick was located 
near latitude 15.1 North, longitude 101.8 West.  Rick is moving 
toward the north-northwest near 6 mph (9 km/h).  A 
north-northwestward to northward motion is expected over the next 
couple of days.  On the forecast track, the center of Rick will 
approach the coast of Mexico on Sunday and Sunday night.
 
Data from an Air Force Reserve Hurricane Hunter aircraft indicate 
that the maximum sustained winds are near 85 mph (140 km/h) with 
higher gusts.  Rick is expected to resume strengthening by tonight 
and become a major hurricane on Sunday. 
 
Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 60 miles
(95 km).
 
The minimum central pressure estimated from the aircraft 
observations is 978 mb (28.88 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected within the Hurricane
Warning area by late Sunday, with tropical storm conditions
expected by Sunday afternoon.  Tropical storm conditions are
expected within the Tropical Storm Warning areas by Sunday
afternoon.
 
STORM SURGE:  A storm surge is expected to produce significant
coastal flooding in areas of onshore winds near and to the east of
where the center of Rick makes landfall in southwestern Mexico.
Near the coast, the surge will be accompanied by large and
destructive waves.
 
RAINFALL:  Rick is expected to produce 5 to 10 inches of rain with
isolated storm total amounts of 20 inches across coastal sections of
the Mexican states of Guerrero and Michoacan from tonight through
Tuesday.  This heavy rainfall will likely produce flash flooding and
mudslides.
 
SURF: Swells generated by Rick will affect portions of the
southwestern coast of Mexico through early next week. These swells
are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
