Storm Events Database Version 3.0
NCDC is announcing the release of version 3.0 of the Storm Events Database. The Storm Events Database contains archived National Weather Service (NWS) storm data and unusual weather phenomenon reports. These include the occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, or disruption to commerce. Rare and unusual weather phenomena that generate media attention, such as snow flurries in South Florida or the San Diego coastal area, are also included in the Database. Additionally, it includes other significant meteorological events such as record maximum or minimum temperatures or precipitation that occur in connection with another event.
The Storm Events Database contains data and information for the United States, its territories, and possessions. Data are available from 1950 to the present, and the Database contains over 1.2 million records. Data are updated monthly with up to a 90-day delay due to the time required to collect and verify the information. The Storm Events Database also allows users to search for various types of storms recorded by state, county, and event type. The data contain a chronological listing, by state and county, of hurricanes, tornadoes, thunderstorms, hail, floods, drought conditions, lightning, high winds, snow, temperature extremes, and other weather phenomena.
Version 3.0 of the Database now contains several new features, which include tornado, hail, and thunderstorm wind data from 1950 to 1995. With version 3.0, users can now search by county for all events whereas some event types were only searchable using NWS forecast zones previously. Many of the events cataloged in the Database also contain narratives, and users can now search through the text of these episode narratives with the new functionality in version 3.0. Images, which are included in Storm Data Publications, are also now available for 61% of the events between 1959 and 1992 in the Database.
