There are lots more resources online about the Tuscaloosa storm, but the most useful I pulled from this Metafilter post: a zoomable “slider” graphic showing before-and-after satellite photos of the tornado’s path.

There are also some similar graphics at the Tuscaloosa News site.

Finally, my friend Quin — a Malleteer, former Army Ranger, and EMT working in Tuscaloosa — was interviewed by the Washington Post for a story that is worth your time.
