DISCUSSION AND OUTLOOK
----------------------
At 700 PM CDT (0000 UTC), the eye of Hurricane Hanna was located
near latitude 26.7 North, longitude 97.5 West. Hanna is moving
toward the west-southwest near 8 mph (13 km/h) and this motion is
expected to continue through Sunday. On the forecast track, the
center of Hanna should continue to move farther inland over southern
Texas tonight and move into northeastern Mexico on Sunday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Rapid weakening is expected as Hanna moves farther inland.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).

The estimated minimum central pressure based on surface
observations is 975 mb (28.79 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hanna can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and
on the web at www.hurricanes.gov/text/MIATCDAT3.shtml.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Baffin Bay to Port Aransas including Corpus Christi Bay...4-6 ft

Port Mansfield to Baffin Bay...2-4 ft

North of Port Aransas to Sargent including Copano Bay , Aransas
Bay, San Antonio Bay, and Matagorda Bay...2-4 ft

Mouth of the Rio Grande to Port Mansfield...1-3 ft

North of Sargent to High Island including Galveston Bay...1-2 ft

The deepest water will occur along the immediate coast near and to
the right of the landfall location. Surge-related flooding depends
on the relative timing of the surge and the tidal cycle, and can
vary greatly over short distances. For information specific to your
area, please see products issued by your local National Weather
Service forecast office.

WIND: Hurricane conditions will continue in portions of the
hurricane warning area through this evening. Tropical storm
conditions are occuring in portions of the tropical storm warning
area and will spread farther inland tonight and Sunday.

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 3 to 5 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 this evening and overnight
over parts of the lower to middle Texas coastal plain.
