UPDATE: Google MAPS has new imagery too, showing even more dramatic views. HUNDREDS of blue tarp roofs and missing trees. Dumpsters parked in yards for clean up. Pan around the map below, or click it's link to view larger.
Compared to what was previously available, the new imagery is stunning. In addition to the tornado damage, you can see new construction which was not depicted until now. The new Lowry Bridge, The Twins Stadium, Gophers Stadium. I'm sure I'll be exploring all night. I recommend you open up Google Earth and take a look!
