The NCEI Storm Events Database contains various types of storm reports searchable by state, county, date, and event type from 1950 to the present. Data are also available in comma-separated value (CSV) files, as entered by NOAA's National Weather Service (NWS).
Severe Weather Data Inventory (SWDI)
SWDI includes data from a variety of sources in NCEI's archive. SWDI provides the ability to search through all of these data to find records covering a particular time period and geographic region, and to download the results of your search in a variety of formats. The formats currently supported are Shapefile (for GIS), KMZ (for Google Earth), CSV, and XML.
International Best Track Archive for Climate Stewardship (IBTrACS)
IBTrACS provides tropical cyclone best track data in a centralized location to aid understanding of the distribution, frequency, and intensity of tropical cyclones worldwide.
