Online Version History:
Version 1.0 (1999): Online access to the Storm Events Database was first provided in 1999. Most of the data from 1950-present is available, although there are inconsistencies in the data fields which cause some data to be inaccessible from the online search system.

Version 2.0 (Apr 3, 2012): Major architecture and system changes required the complete rebuild of the Storm Events Database in 2012. A new, stricter database structure is now used, but significant work is needed to reload the original formats of data and fix data inconsistencies.

Version 2.2 (May 1, 2013): Addition of data from 1996 to 2000.

Version 3.0 (May 12, 2014): Addition of data from 1950 to 1996. CSV exports of entire database (1950-Present) are now available. Major improvements to the web application including:
