Link to the Reanalysis Data
The Atlantic Hurricane Database Re-analysis Project is an effort to extend and revise the National Hurricane Center's North Atlantic hurricane database (or HURDAT). Going back to 1851 and revisiting storms in more recent years, information on tropical cyclones is revised using an enhanced collection of historical meteorological data in the context of today's scientific understanding of hurricanes and analysis techniques.

April 2022 - The Atlantic and Norht East/North Central Pacific hurricane seasons for 2021 have been added to the hurricane databases (HURDAT2). Of note is that Radius of Maximum Wind (RMW) has been included for the first time.
February 2022 - Reanalysis of the 1966 to 1970 Atlantic Hurricane Seasons:
A systematic study of the 1966 to 1970 Atlantic hurricane seasons has discovered 14 new tropical storms. Additionally, two new hurricanes were diagnosed, which previously were only considered to be a tropical depression (AL151970) and a tropical storm (AL081970). These systems were all added into the hurricane database (HURDAT2) based upon a re-examination of all weather station, ship, Hurricane Hunter, and satellite observations using today's understanding of tropical cyclone structure and life cycle. On the flip side, two major hurricanes (Francelia - AL131969 and Inga - AL201969) were downgraded to a Saffir-Simpson Hurricane Scale category 2 hurricane. For U.S. hurricanes, 1966's Alma (AL011966) was upgraded from a Category 2 to a Category 3 hurricane impact in southwest Florida, 1966's Inez (AL091966) was upgraded from a Category 1 to a Category 2 hurricane in south Florida, 1970's Celia (AL041970) was upgraded from a Category 3 to a Category 4 hurricane in lower Texas, and 1969's Gerda (AL161969) was downgraded from a Category 1 hurricane to a tropical storm in Maine.
