A realistic worse-case scenario for Texas
There is a significant chance that Ike will be the worst hurricane to hit Texas in over 40 years. The latest run of the HWRF and GFDL models paint a realistic worst-case scenario for Texas. These models bring Ike to the coast as a Category 4 hurricane (which I give a 20% probability of happening). The HWRF predicts a 170-mile stretch of coast will receive hurricane force winds of 74 mph or greater. A 100-mile stretch of coast will receive winds of Category 3 strength and higher, 115 mph. Hurricane force winds will push inland up to 50 miles, along a 50-mile wide region where the eyewall makes landfall. A 100-mile stretch of Texas coast will receive a storm surge of 10-15 feet, with bays just to the right of where the eye makes landfall receiving a 20-25 foot storm surge. This is what Hurricane Carla of 1961 did to Texas. Carla was a Category 4 hurricane with 145 mph winds at landfall, and drove a 10 foot or higher storm surge to a 180-mile stretch of Texas coast. A maximum storm surge of 22 feet was recorded at Port Lavaca, Texas. Despite the fact that the center of Carla hit over 120 miles southwest of Houston, the hurricane drove a 15-foot storm surge into the bays along the south side of the city.
