Weather of Biblical Proportion

I can't help but notice, no one in the Republican party drew a parallel between Tropical Storm Isaac and the Republican National Convention. Other than to quietly postpone it a day or two. Now, when Katrina hit, I remember Pat Robertson clearly drew a line between some of the New Orleans lifestyle and the hurricane. And since Isaac has changed course, maybe the RNC does believe they were deserving of the mercy, I don't know. What I've been wondering about, though, is why we don't consider weather to be a sign, good or bad, from G-d. Other nations, not even Bible-believing G-d fearing nations, know their weather comes from above. I don't know if we, here in America, believe our weather comes from science, comes from chance, or only comes in judgment on someone else, but we don't align inclement weather with a message from G-d, unless it's in judgment of others. Now that Isaac has changed course, it would seem that there is a potentially vast portion of our country affected. The beginning of the RNC was postponed due to the Storm, then it changed directions and is heading right for the same region that was hit by Katrina, on the 7th anniversary of that storm's landfall. I see enough in all of this to say G-d would probably like the attention of more than just the wild ones in the French Quarter and more than just the republicans. I'm thinking He'd like America in general to get off of our arrogant high horses, quit blaming each other and the rest of the world, and stop proclaiming that G-d and mammon are compatible in our lives. Although the message of repentance was and is to the general population, it isn't going to be received or done en mass nationally. But for those with eyes to see and ears to hear, it's time. Seven is a big number in G-d's math and storms at sea are nothing new in his methods of dealing with humanity. As a matter of fact, we've actually been forewarned that the circumstances of Jonah would be the only sign. Looks like we're in for some bad weather and the message is REPENT!
But he answered and said unto them, An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas:
