I don't think we can ever know for sure whether situations like Hurricane Katrina are judgments from God or not. But a few things are certain: God controls the weather, just as he controls everything else. His ways are higher than ours. He does judge both men and nations.
While others debate about whether Hurricane Katrina was a judgment or not, I'd like to point you to a slightly different perspective: Was Hurricane Katrina 'Intelligent Design?'
