Lili's 2002 demise

I think we all kind of thought this was the case. Now there is evidence to prove it, apparently.

Thats what I think killed Katrina,Dennis,Ivan...Dry air gets sucked into the storm as it moves at the northern gulf coast.

seems like it to me too

I will have to disagree with these results. At the 2004 AMS trop met conference, it was shown that it was an increase in shear that killed Lili

There was dry air in the WGOM, but it did not reach the hurricane until the weakening process had already begun

JUST like Katrina

friction from land also helped Katrina and likely helped with Lili which could have been devestating if it didnt weaken

>>Dry air gets sucked into the storm as it moves at the northern gulf coast.

Depends on the storm. When they're abutted against a frontal trough, usually that will be the case (often resulting in a lopsided storm). But look at Cindy. It was the opposite (or the 90 degree Texas effect) where the land drew the center tighter. IMHO, there is no "definite" one way or the other.

I for one am VERY thankful Lili weakened. She still was a damaging storm but Lafayette and surrounding areas would have been absolutely devastated by the winds which were forecast to be 135mph+ in the city. Hopefully we don't have a scare like that for a long long time, especially after the 2005 season...my nerves wouldn't be able to take it!

Katrina's core didn't interact with dry land until she crossed the Mississippi coast. All of SE Louisiana was underwater......MGC

You gotta leave those CAT 5s alone

[Innotech]

yeah if Lili had been a Cat 4 through Lafayette, my house might not have made it unscathed. We're inland, but the coast of Louisiana is a marsh and not exactly protective.
