Katrina's hurricane force winds extended out only about 30 miles from the center when it hit land, wilma's hurricane foruce winds extended out 86 miles from the center when it left the coast of florida. the tropical storm force winds extend out about 200 miles from the center in both storms. The only major difference in damage from katrina to wilma is after katrina 3 levies broak and flooded a city, and that was not directlyed related to the hurricane.
