Tropical Cyclone Reports
The National Hurricane Center's Tropical Cyclone Reports (formerly called Preliminary Reports) contain comprehensive information on each storm, including synoptic history, meteorological statistics, casualties and damages, and the post-analysis best track (six-hourly positions and intensities).
Atlantic, Caribbean, and the Gulf of Mexico
Eastern Pacific (out to 140°W)
* Note: 1958-1994 for the Atlantic, Caribbean, and the Gulf of Mexico
and 1988-1994 for the Eastern Pacific are scanned images of the printed
An XML index file is also available for all the Tropical Cyclone Reports.
Tropical Cyclone Advisory Archive
NHC's Tropical Cyclone Advisory Archive is the complete set of tropical cyclone text advisories and graphic images that were issued during the hurricane season.
The tropical cyclone graphics archives are accessed through the Graphics Archive link at the top of the individual storm archive pages (graphics from the mid-2000 season and later are available).
* Note: Advisories prior to 1999 are largely scanned images of the printed bulletins. Not all advisories are available
Graphical Tropical Weather Outlook
The graphical Tropical Weather Outlook (TWO) is a web display intended to be a visual companion product to the text TWO. Archives are available for both the Atlantic and East Pacific basins.
Marine & Advisory Text Products
Use the drop-down below to access NHC's past plain-text forecasts and advisories. They are sorted by
Marine Graphical Products
The National Climatic Data Center (NCDC) archives most of the marine graphical products produced
by the Tropical Analysis & Forecast Branch (TAFB). These charts can be found at the link below,
mostly in the 'Ocean Analysis' and 'Ocean Forecast' sections.

Best Track Data (HURDAT2)
Atlantic hurricane database (HURDAT2) 1851-2017 (5.9MB download)
This dataset was provided on 1 May 2018 to include the 2017 update to the best tracks.
This dataset (known as Atlantic HURDAT2) has a comma-delimited, text format with six-hourly information on the location, maximum winds, central pressure, and (beginning in 2004) size of all known tropical cyclones and subtropical cyclones. The original HURDAT database has been retired.
Northeast and North Central Pacific hurricane database (HURDAT2)
1949-2017 (3.3MB download)
This dataset was provided on 11 May 2018 for the 2017 tropical cyclone season.The best tracks provided in this database for the following systems in the Central Pacific Hurricane Center area of responsibility (between 140 and 180W longitude) are operational estimates and have not yet been post-storm analyzed: Halola (CP012015), Kilo (CP032015), Loke (CP042015), Pali (CP012016), Darby (EP052016), Madeline (EP142016), and Fernanda (EP062017). The final best tracks for these systems will be updated when they become available.
This dataset (known as NE/NC Pacific HURDAT2) has a comma-delimited, text format with six-hourly information on the location, maximum winds, central pressure, and (beginning in 2004) size of all known tropical cyclones and subtropical cyclones. The original HURDAT database has been retired.

Past Track Seasonal Maps
Use the drop-down menus below to access a track map image for the specified season. These images are based on the HURDAT best track database and available in Portable Network Graphics (.png) format.
East Pacific Basin
Note: Image sizes can vary from 130K to about 3M.
Past Track Maps of U.S. Landfalling Major Hurricanes
The images below are from the NHC's Deadliest, Costliest, and Most Intense United States Tropical cyclones report.
Tropical Cyclone GIS Data Format
NOAA's Coastal Services Center maintains a detailed online interactive mapping tool called Historical Hurricane Tracks at www.coast.noaa.gov/hurricanes. This tool offers users the ability to search and display global tropical cyclone data. The information can also be downloaded in widely-used GIS data formats.
When using the Historical Hurricane Tracks tool, the left side bar allows you to query storms by their location, name, year, etc. Search options can easily be refineed for the storm (or storms) that are of interest to the user. Please note that the Historical Hurricane Tracks interface will not contain data for the current season until the storms have had their entire datasets analyzed. For example, the 2013 season should be online by early 2014.
Tropical Cyclone 'Storm Wallet' Electronic Archive
After the dissipation of every tropical cyclone occurring in the Atlantic and eastern north Pacific basins, all of the data and relevant materials related to that cyclone are collected by the NHC staff. The materials are placed in a "storm wallet" which currently takes the form of an expandable binder, or series of binders. These storm wallets have proven to be extremely useful in the post-analysis of many tropical cyclones, both near-term and in some cases, decades later.
The procedure for storing this data dates back to well before the routine use of computers in the office environment. In the Atlantic, the wallet series begins in 1958 and proceeds continuously through the present. In the eastern north Pacific, wallets begin in 1988, the year in which operational responsibility for that basin was assumed by NHC.
In an effort to make this material more accessible, the NHC is currently engaged in a project supported by the NOAA Climate Database Modernization Program (CDMP) to optically scan the entire wallet archive and post it on-line. As the project is currently underway, scanned material will be posted as it becomes available.
The scanned documents are available in both JPG and PDF formats. By selecting the link below, you will be directed to a location that contains a series of text files which index the available storm data. You will also see separate directories of both JPG and PDF files which can be accessed to view the data.
Tropical Cyclone Monthly Summary Archive
At the end of each month during the hurricane season the NHC releases a brief summary of the tropical cyclone activity during the month. These summaries are viewed as interim to the Tropical Cyclone Reports, which are much more comprehensive. The November summary reviews the tropical cyclone activity over the course of the entire season.
Tropical Cyclone Annual Summaries 1872-2006 (Monthly Weather Review)
Monthly Weather Summaries of the hurricane seasons for the years 1872 - 2009 are available from the NHC Library. The Monthly Weather Summaries were published by the U.S. Weather Service between 1872-1973. Since 1974 the Monthly Weather Summaries have been published by the American Meteorological Society.
Tropical Cyclone Seasonal Outlook and Summary ArchiveThe Climate Prediction Center (CPC) provides annual hurricane season outlooks in May, and an update in August. A seasonal hurricane summary is also provided.
View the CPC archive of hurricane season outlooks.
Tropical Cyclone Climatology
View our graphics and information on the climatology of hurricane season in terms of the total number of tropical systems and hurricanes produced throughout the year in the Atlantic and East Pacific basins.
The National Climatic Data Center provides a monthly State of the Climate focus on Hurricanes & Tropical Storms and other relevant climate data.
Tropical Cyclone Forecast Verification
The NHC receives frequent inquiries on the accuracy and skill of its forecasts and of the computer models available to it. To help answer these questions we offer a Verification/Forecast Accuracy section. Here you will find information on current and historical NHC forecast errors.
Reconnaissance Data Archive
Additional reconnaissance data archives are available in the storm wallet electronic archive above.
