SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * Port Mansfield to Port Aransas A Tropical Storm Warning is in effect for... * Barra el Mezquital Mexico to Port O`Connor Texas A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 24 hours in the indicated locations. 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 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. Interests in northeastern Mexico should also monitor the progress of this tropical storm. 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 100 AM CDT (0600 UTC), the center of Tropical Storm Hanna was located near latitude 26.5 North, longitude 98.5 West. Hanna is moving toward the west-southwest near 9 mph (15 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 this morning and move into northeastern Mexico later today. Maximum sustained winds have decreased to near 70 mph (115 km/h) with higher gusts. Rapid weakening is expected today as Hanna moves farther inland. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. A Texas Mesonet Station northeast of Edcouch, Texas, recently reported a sustained wind of 48 mph (77 km/h) and a wind gust of 68 mph (109 km/h). The estimated minimum central pressure is 983 mb (29.03 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 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: Tropical storm conditions are occuring in portions of the tropical storm warning area and will spread farther inland overnight 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 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 overnight over parts of the lower to middle Texas coastal plain. NEXT ADVISORY ------------- Next complete advisory at 400 AM CDT. $$ Forecaster Cangialosi |
