The table below provides links to comma separated value (.csv) files for tornado, hail, and damaging wind data as compiled in Storm Data.
Tornado reports exist back to 1950 while hail and damaging wind reports date from 1955. The full datasets are very large, especially hail and wind. To facilitate quicker downloads these data have been parsed by decade (or 1/2 decade in the case of wind/hail data in the 1950s and 2000s).
This document describes the format of the .csv files.
Please note! Erroroneous tornado, hail, and wind report locations for Oct-Dec, 2006 were corrected on Jan. 12, 2008.
All data for 2008 should be available by late March
