DISCUSSION AND OUTLOOK
----------------------
At 700 AM CDT (1200 UTC), the center of Hurricane Agatha was
located near latitude 14.1 North, longitude 99.0 West. Agatha is
moving toward the north-northwest near 3 mph (6 km/h).  A turn
toward the northeast is expected later today, with a slow motion
toward the northeast continuing through Monday night.  On the
forecast track, the center of Agatha will approach the southern
coast of Mexico later today and make landfall there on Monday.

Maximum sustained winds have increased to near 75 mph (120 km/h)
with higher gusts.  Additional intensification is anticipated up 
until landfall on Monday.

Hurricane-force winds extend outward up to 20 miles (30 km) from 
the center, and tropical-storm-force winds extend outward up to 
80 miles (130 km) from the center.

The estimated minimum central pressure is 987 mb (29.15 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the hurricane warning
area and possibly in the watch area on Monday, with tropical storm
conditions beginning late tonight or early Monday. 

STORM SURGE:  Storm surge is expected to produce 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 by later today into 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 Vera Cruz and Tabasco: 2 to 4 inches, with
isolated maximum amounts of 6 inches possible.

SURF:  Swells generated by Agatha will affect the coast of southern 
Mexico during the next few days.  These swells are likely to cause 
life-threatening surf and rip current conditions.  Please consult 
products from your local weather office.
