Readers, be sure an update your link to the graph of the annual tornado statistics. NOAA appears to be changing things around, perhaps even for the better.

But if you do a google search for "tornado statistics," it will still most likely lead you back to the old page which has incomplete tables, especially no titles for the column headings.

Warning Coordination Meteorologist's Introduction
Welcome to the WCM Page for the SPC. This page has charts of the latest preliminary severe storm reports, annual summaries, and links to comma-separated-value (csv) data files from the SPC severe weather database back to 1950. As time allows, this page may occasionally serve as a place for preliminary severe weather event assessments. For additional insight into severe thunderstorms and tornado reports, the SPC and the National Severe Storms Laboratory are collaborating on posting non-operational "feature" content to the U.S. Severe Weather Blog, hosted by NOAA Public Affairs in Norman, Oklahoma.
