DISCUSSION AND OUTLOOK
----------------------
At 100 PM CDT (1800 UTC), the center of Hurricane Agatha was located
near latitude 15.4 North, longitude 96.9 West. Agatha is moving
toward the northeast near 8 mph (13 km/h) and this general motion is
expected to continue through Tuesday.  On the forecast track, the
center of Agatha will make landfall in the state of Oaxaca, Mexico,
during the next few hours.
 
Maximum sustained winds are near 105 mph (165 km/h) with higher
gusts.  Little change in strength is expected before Agatha
reaches the coast of Oaxaca.  Rapid weakening is forecast after
landfall, and Agatha is expected to dissipate over southeastern
Mexico by late Tuesday.
 
Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).  An observation in Puerto Angel recently reported a
wind gust of 40 mph (65 km/h).
 
The minimum central pressure based on data from the Air Force 
Hunter aircraft is 974 mb (28.76 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the hurricane warning
area and possible in the watch area through this evening.  Tropical
storm conditions are occurring along the coast of Oaxaca and will
spread eastward within the warning area through tonight.
 
STORM SURGE:  Storm surge is expected to produce extremely dangerous
coastal flooding in areas of onshore winds near and to the east of
where the center of Agatha makes landfall.  Near the coast, the
surge will be accompanied by large and destructive waves.
 
RAINFALL: Agatha will produce heavy rains over portions of southern
Mexico through Tuesday night. The following rainfall amounts are
currently expected:
 
Mexican state of Oaxaca: 10 to 16 inches, with isolated maximum
amounts of 20 inches possible. Life-threatening flash flooding and
mudslides may occur.
 
Mexican state of Chiapas: 5 to 10 inches, with isolated maximum
amounts of 15 inches possible. Life-threatening flash flooding and
mudslides may occur.
 
Mexican states of Veracruz, Tabasco and eastern portions of
Guerrero: 2 to 4 inches, with isolated maximum amounts of 6 inches
possible.
 
SURF:  Large swells generated by Agatha will affect the coast of
southern Mexico during the next day or so.  These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
