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.

What's New

June 2019 - The 2017 Best Tracks for the Atlantic basin has been added into the HURDAT2 database.

Dec 2018 - Two new articles

Note: Tbe following storms that formed within the Central Pacific Hurricane Center's area of responsibility are operational estimates and have not yet been post-storm analyzed:

  • Halola (CP012015)
  • Kilo (CP032015)
  • Loke (CP042015)
  • Pali (CP012016)

The final best tracks for these systems will be updated when they become available.
