DISCUSSION AND OUTLOOK
----------------------
At 100 AM CDT (0600 UTC), the center of Hurricane Agatha was located
near latitude 14.6 North, longitude 98.0 West. Agatha is moving
toward the northeast near 6 mph (9 km/h), and this general motion is
expected to continue today.  On the forecast track, the center of 
Agatha will make landfall in the state of Oaxaca, Mexico, this 
afternoon or evening.

Maximum sustained winds remain near 110 mph (175 km/h) with higher
gusts.  Agatha could still strengthen today before reaching the 
coast of Oaxaca.  Rapid weakening is expected over southeastern 
Mexico tonight and on Tuesday after Agatha moves inland.

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).

The estimated minimum central pressure is 964 mb (28.47 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the hurricane warning
area and possible in the watch area by this afternoon or this 
evening, with tropical storm conditions beginning this morning.

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.

Eastern portions of the Mexican state of Guerrero: 2 to 6 inches,
with isolated maximum amounts of 10 inches possible.
Life-threatening flash flooding and mudslides may occur.

Mexican states of Veracruz and Tabasco: 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 couple of days.  These swells are
likely to cause life-threatening surf and rip current conditions.
