I found this a while back... it has all US tornado tracks/severity from 1950-2008: http://www.srh.noaa.gov/gis/kml/TIMS/ The paths are lines from the approximate start and end points for the tornadoes and do not show the actual meandering paths.
For a Google Earth class I was teaching, I pulled out the Michigan data and normalized it to show for all Michigan tornadoes<https://sites.google.com/site/gemapsamples/home/michigan-tornadoes-1950-2008>what their paths were from their geographic center. The resulting KMZ <https://docs.google.com/leaf?id=0B0nN2a_xojvPZDJkYmM2MzktNmE3Ny00ZjYwLWE5YzAtN2NmZTE3MWU5NjA4&hl=en_US&authkey=CPruvsgC>shows that many tornadoes traveled in unexpected directions. One of my students was able to find the path of a tornado that tracked through a wooded property he co-owned in northern Michigan and compare the start/end approximate path with the actual path evident in the change in vegetation viewable in the Google Earth base imagery. --Roger Rayle-- On Fri, Jun 3, 2011 at 4:46 PM, Harry Tasset <[email protected]> wrote: > Just wondering if anyone out there knows of any overlays showing the path > of destruction for historical > and recent tornadoes?
