Great images Cape, and I think that lower one explains a lot of why Hattiesburg received so much damage--it's right off the NE quadrant at the end of that lower loop.

Can anyone remember another storm that lost it's entire western half? I mean I have never seen a storm look like that ever. Also, how did the eye manage to stay so strong even though the western half was all but gone. That is totally bizarre.

Yay! 1000 posts now. :D

Congratulations, jason0509!

Yep, I agree... it's interesting how Katrina still had such a well-defined eye on both visible and infra-red imagery despite being sheared and entraining dry air on the western side. Very interesting.

i think another question that should be looked at is surge, lili, katrina and ivan all weakened before landfall, yet ivan and katrina had horrific surge yet lili did not, why did katrina and ivan keep such a high surge?

Lili had a smaller wind field, though it still mnaged to produce about 12 feet of surge... just over an unpopulated area

Derek, I read somewhere that Wilma's large eye caused her to fend off the shear more. Do you think if Lili or Katrina had a huge eye like Wilma's, they'd not have weakened so much?

Katrina and Rita had large eyes too.

The thing was Wilma headed in an west-east trajectory so the trough aided its outflow instead of shearing it, allowing it to strengthen. OTOH K and R were heading mostly in a northerly trajectory, so the shear hit them perpendicularly, causing a lot more damage. In fact, one of Derek's forecasts for Wilma outlined the scenarios. He specifically stated that the trough could either hurt Wilma by shearing it or help it by enhancing outflow. Of course the second scenario verified.

If I am wrong then correct me.

I think it was more of the motion, so that the storm relative shear remained quite low over Wilma
