On the first anniversary of our web page--May 1st, 1997--we began supplying information about the locations of tornadoes that have occurred in every state in the USA. In October of 2000, we began our worldwide tornado pages.
We intend to supply the US data in three steps:
- The first step is to put up the information for all US tornadoes from 1950 to 1995.
- The second step is to put up the eastern US information, back to 1700.
- The third step to put up information for all US states back to 1800, or as far as we can.
All tornadoes regardless of intensity will be included.
Some of this data is already available in zipped form at the Storm Prediction Center site, but we intend to extend the data base as well and provide it in an easy to access form. It will complement their data, not attempt to eliminate the need for it or replace it.
