Joplin Tragedy

It was a single, huge tornado (though with multiple vortices) that stayed close to the ground and at times moved very slowly, as when it seemed to stay surrounding the Joplin, Missouri hospital.  With 116 dead so far, it is the most destructive single tornado in the U.S. since 1947.

And while the search for dead and injured goes on, more threatening weather is forecast for late Tuesday, including the possibility of more tornadoes.
