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
Atlantic, Caribbean, and the Gulf of Mexico
Eastern Pacific (out to 140°W)

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 1998 are scanned images of the printed bulletins.
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.

Best Track Data (HURDAT2)
Atlantic hurricane database (HURDAT2) 1851-2012 (5.5MB download)
This dataset was provided on 15 February 2013 to include the 2012 hurricane season.
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 sibtropical cyclones.
The original HURDAT database has been retired.
Detailed information regarding the
Atlantic Hurricane Database Re-analysis Project is available from the
Hurricane Research Division.
Northeast and North Central Pacific hurricane database (HURDAT2)
1949-2012 (2.8MB download)
This dataset was provided on 4 April 2013 to include the 2012 hurricane season.
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

season. These images are based on the HURDAT best track database and
available in Portable Network Graphics (.png) format.

Tropical Cyclone GIS Data Format
The NHC maintains an archive of GIS data that is produced in-house. If interested, please provide your feedback and need for NWS GIS data in this National Weather Service GIS Survey.
To see other National Weather Service data available in GIS formats, please visit www.weather.gov/gis.
NOAA's Coastal Services Center maintains a detailed online interactive mapping tool called Historical Hurricane Tracks at www.csc.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 2012 season should be online by early 2013.
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
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
Tropical Cyclone Seasonal Outlook and Summary Archive
The Climate Prediction Center (CPC) provides annual hurricane
season outlooks in May, and an update in August. A seasonal hurricane summary is also provided.

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.
