DISCUSSION AND OUTLOOK ---------------------- At 400 AM CDT (0900 UTC), the center of Tropical Storm Hanna was located near latitude 26.3 North, longitude 98.9 West. Hanna is moving toward the west-southwest near 9 mph (15 km/h) and this motion is expected to continue through Monday. On the forecast track, the center of Hanna should continue to move farther inland 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 Airport in McAllen recently reported a wind gust of 54 mph (87 km/h). The estimated minimum central pressure is 988 mb (29.18 inches).

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.
