Storm Spotter Questions

Miscellaneous Questions

1. Where is tornado alley located?

  • There are different ways to create maps of tornado alley, the area of relatively high tornado occurrence in the USA, depending on the factors you consider. Dr. Harold Brooks of the National Severe Storms Laboratory has derived an image based on the number of tornado days per year from 1980-1999.
