For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Tropical Storm Hanna was located near latitude 26.2 North, longitude 99.1 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 through tonight. Maximum sustained winds are near 50 mph (85 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 later today 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. A wind gust of 49 mph (80 km/h) was reported within the past couple of hours at Port Isabel-Cameron County Airport. The estimated minimum central pressure is 992 mb (29.29 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: 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.

For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A Tropical Storm Warning means that tropical storm conditions are occurring within the warning areas. Interests elsewhere along the Texas coast should monitor the progress of Hanna.

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 Baffin Bay, Corpus Christi Bay...4-6 ft Port Mansfield to Baffin Bay...2-4 ft Port Aransas to Port O'Connor including Aransas Bay...2-4 ft Mouth of the Rio Grande to Port Mansfield...1-3 ft North of Port O'Connor 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 for a few more hours.
