Sad to say, this is not some sort of spoof.
In the early hours of this morning, a tornado (a rare thing indeed round that way) ripped through the town of San Pedro in the Misiones region of Argentina (its northernmost tip, see map) and left 10 people dead and over 50 injured. Check out a video display on this page over at Clarín for evidence of the devastation.
Knowing the area personally (from an extended stay a few years ago) and the wonderful, generous people that live there, my heart goes out. Those of you sitting in the twister zones up North have a better idea of what these people have just been through.
