Hurricane Ike is a monster. Don't let the "category" or top wind speeds fool you. Even though Ike is "only" a strong Cat 2 or weak Cat 3 hurricane, it will impact the Texas coast as if it were a Cat 4 or 5. This is because the sheer size of the storm will generate a prolific storm surge -- possibly as high as 25 feet!
