Dan, I think some rabbis would agree with you. Remember that Hurricane Katrina came shortly after the expulsion of Jews from Gush Katif.
Also, I went to a Hineni lecture a few months ago given by Rebbetzin Esther Jungreis, who said in essence that these bad things are happening, measure for measure when the world goes against Israel. She also brought up Hurricane Katrina, along with the French riots. France has given money to the moose-limbs, and they've pressured Israel. So in return, they've gotten riots. Their own policemen referred to it as an intifada.
Ok I will say two things in regards to this:
1. A mortal..a human being has to be careful when attempting to equate Gd's natural disasters and human's evil ways. Coming to definite conclusions can be an act of arrogance and in actuality go against Gd. Who are we to be able to interpret His actions?! Is death a punishment? Is suffering a punishment? Maybe it's a blessing. Maybe suffering in one's life for a period time leads to good things..maybe suffering for 2000 years leads to good things...On the other hand, we should prefer life and no suffering over the opposite when given the choice. But when good things happen to bad people one can easily say, "Oh, we were right this whole time look at us."
2. On the other hand, being evil, being Gdless, makes you forget about the important things in life. You forget to repair the levees. You forget that they are broken..and then when that big hurricane comes, the righteous, the evil, and the innocent alike get consumed by that flood. Therefore, for a community to be evil has a direct consequence when a disaster stops by. However, I will say that a lot of the time, if it is meant to be, the righteous will be spared a lot of the time. However, it is not for any of us to judge anything or draw definite conclusions. We can say, "Perhaps Gd did it for this reason, but who am I to think for Gd?"
