DISCUSSION AND OUTLOOK

At 100 PM CDT (1800 UTC), the center of Tropical Storm Carlotta was
located by satellite and Acapulco radar near latitude 16.0 North,
longitude 99.4 West.  Carlotta is moving toward the northeast near 5
mph (7 km/h).  On the forecast track, the center of Carlotta is
expected to make landfall on Saturday within the warning area and
move farther inland on Sunday.

Maximum sustained winds have increased to near 40 mph (65 km/h) with
higher gusts.  Some further intensification is possible today.
Carlotta is forecast to quickly weaken after landfall on Saturday,
and then dissipate on Sunday.

Tropical-storm-force winds extend outward up to 30 miles (45 km)
from the center.

The estimated minimum central pressure is 1006 mb (29.71 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Carlotta is forecast to produce 3 to 6 inches of rainfall
along the Guerrero and Oaxaca coasts, including the city of
Acapulco, with isolated higher amounts of 10 inches possible.  These
rains are likely to produce life-threatening flash floods and
mudslides, especially in areas of higher terrain.  Farther inland
across the states of Guerrero and Oaxaca, rainfall amounts of 1 to 2
inches with isolated amounts of 4 inches are forecast.

WIND:  Tropical storm conditions are expected within the warning
area starting early Saturday.

SURF:  Swells generated by Carlotta 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.
