DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 400 AM CDT (0900 UTC), the center of Hurricane Katia was located
near latitude 21.5 North, longitude 94.5 West. Katia is stationary
and little overall motion is anticipated through late today, but
then the hurricane is forecast to turn southwestward and approach
the coast within the watch area late Friday or early Saturday.

Maximum sustained winds remain near 80 mph (130 km/h) with higher
gusts.  Some strengthening is forecast during the next 48 hours and
Katia could be near major hurricane strength at landfall.

Katia is a small tropical cyclone. Hurricane-force winds extend
outward up to 10 miles (20 km) from the center and tropical-storm-
force winds extend outward up to 45 miles (75 km).

Hurricane-force winds extend outward up to 10 miles (20 km) from the
center and tropical-storm-force winds extend outward up to 70 miles
(110 km).

The estimated minimum central pressure is 989 mb (29.21 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  A dangerous storm surge will raise water levels by
as much as 5 to 7 feet above normal tide levels near and to the
north of where Katia makes landfall. Near the coast, the surge will
be accompanied by large and destructive waves.

RAINFALL:  Katia is expected to produce total rain accumulations of
5 to 10 inches over northern Veracruz, and 2 to 5 inches over far
southern Tamaulipas, northeast Puebla, and southern Veracruz through
Saturday morning. Isolated maximum amounts of 15 inches are possible
in northern Veracruz.  This rainfall may cause life-threatening
flash floods and mudslides, especially in areas of mountainous
terrain.

WIND:  Hurricane conditions are expected within portions of the
hurricane warning area by late Friday, with tropical storm
conditions expected within the tropical warning areas by
midday Friday.

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