over northeastern Mexico today and tonight.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Rapid weakening is expected as the center of Hanna moves farther
inland, and the cyclone is expected to weaken to a tropical
depression by tonight and dissipate Monday or Monday night.

Tropical-storm-force winds extend outward up to 115 miles (185 km)
mainly over water to the east of the center.  Miller International

STORM SURGE:  Water levels along the Texas coast will gradually
subside through this morning. Consult products issued by your
local National Weather Service forecast office for additional
information.

WIND:  Tropical storm conditions will continue near the center of
Hanna for the next several hours, and along the Texas and
northeastern Mexican coast in the warning area for a few more hours.

RAINFALL: Hanna is expected to produce total rain accumulations of 6
to 12 inches, with isolated maximum amounts of 18 inches through
Monday in south Texas and into the Mexican states of Coahuila, Nuevo
Leon, and northern Tamaulipas.  This rain will produce
life-threatening flash flooding, rapid rises on small streams, and
isolated minor to moderate river flooding.

Hanna is also expected to produce 2 to 4 inches of rain along the
upper Texas and Louisiana coasts.

SURF:  Swells generated by Hanna will continue to affect much
of the Texas and Louisiana coasts for another day or so. These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather
office.

TORNADOES:  A few tornadoes are possible today into this evening
across parts of south Texas.
