@Geoblogfeed Rare "Perfect Storm

"Monster Alabama Tornado Spawned by " "

The headline above is from today's issue of National Geographic Daily News. A tornado, estimated to be a mile wide and an F5 on the Fujita scale devastated Tusaloosa. The storm system that spawned this tornado has killed 260 people over two days. Meteorologists are trying to determine how long this tornado stayed on the ground, but it could have been hundreds of miles.

I could not explain the science nearly as eloquently as is done in a NASA Earth Observatory discussion of the weather systems that produced the deadly tornados in southeastern U.S. over the past two days, and so here's a link to their site. Here's a video animation of the storm that is absolutely awesome.
