This is the official U.S. government database of storm events around the country. Some of the events tracked are: tornadoes, hurricanes, tropical storms, droughts, snowstorms, flash floods, hail, wild/forest fires, temperature extremes, strong winds, fog, and avalanches.The data is collected by more than 120 National Weather Service forecast offices, including in Alaska, Hawaii, Guam, Puerto Rico, and American Samoa. The data is archived by the National Climatic Data Center.

Fields in the database include: date and time the storm event began; event type; states and counties hit; latitude and longitude; property and crop damage; and injuries and fatalities.

Historical data is available going back to 1950, however the accuracy of the data prior to 1996 is uncertain because of the way the information was archived by NCDC.
