DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM CDT (0900 UTC), the center of Tropical Storm Marty was
located near latitude 16.4 North, longitude 101.7 West. Marty is
drifting toward the east near 2 mph (4 km/h), and a gradual turn
toward the east-northeast is forecast later today.  A turn toward
the north is expected early Wednesday followed by a turn toward the
west-northwest Wednesday afternoon.  On the forecast track, the
center of Marty is expected to be near but just offshore of the
southwestern coast of Mexico today through Wednesday. However, only
a small deviation to the right of the forecast track would bring the
center onshore.

Maximum sustained winds have decreased to near 65 mph (100 km/h)
with higher gusts.  Additional weakening is forecast during the
next couple of days.

Tropical storm force winds extend outward up to 80 miles (130 km)
from the center.

The estimated minimum central pressure is 993 mb (29.33 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are expected within the tropical
storm warning area by midday today.  Tropical storm conditions are
possible within the watch area by tonight.

RAINFALL:  Marty is expected to produce rainfall amounts of 6 to 12
inches over the Mexican state of Guerrero and 2 to 5 inches over the
state of Michoacan through Thursday.  Isolated amounts of 20 inches
are possible in Guerrero from the Sierra Madre del Sur mountains
toward the coast.  These rains are expected to produce life-
threatening flash floods and mud slides, especially in areas of
mountainous terrain.

STORM SURGE:  A storm surge is expected to produce coastal flooding
in areas of onshore flow.  The surge will be accompanied by large
and destructive waves.

SURF:  Swells generated by Marty are affecting portions of the
coast of southern Mexico.  These swells are likely to cause life-
threatening surf and rip current conditions.  Please consult
products from your local weather office.
