DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Tropical Storm Agatha was
located near latitude 13.8 North, longitude 98.1 West. Agatha is
moving toward the north-northwest near 5 mph (7 km/h).  A turn 
toward the northeast is forecast to occur late tonight or Sunday.  
On the forecast track, the center of Agatha will approach the 
southern coast of Mexico on Sunday and make landfall there on 
Monday.

Maximum sustained winds have increased to near 60 mph (95 km/h) 
with higher gusts. Rapid intensification is forecast, and Agatha 
could become a hurricane by early Sunday.

Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.

The estimated minimum central pressure is 998 mb (29.47 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are expected in the hurricane warning
area and possible in the watch area on Monday, with tropical storm
conditions possible Sunday night.  Tropical storm conditions are
expected in the tropical storm warning areas on Monday.

STORM SURGE:  Storm surge is expected to produce significant 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 Sunday 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 are expected to begin affecting
the coast of southern Mexico tonight.  These swells are likely
to cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
