The working best track wind swath is created by accumulating the best track wind radii
over the course of an ongoing tropical cyclone. The working best track wind swath will generally
not exactly match the radii contained in the tropical cyclone advisories. This is because all
of the data in a working best track are subject to modification during the life cycle of the
the cyclone.
(Note: The "working best track" represents the forecasters' best estimates of the
location, intensity, and size of a tropical cyclone while the cyclone is ongoing. After the
life cycle is complete, forecasters prepare a "final best track", using data that might not
have been available operationally, and it is the final best track that represents NHC's official
historical record for the cyclone.)
The working best track wind swath shows how the size of the storm has changed and
the areas potentially affected so far by sustained winds of tropical storm force
(34 Knot), 50 knot and hurricane force (64 knot) from a tropical cyclone. These data are
based on the wind radii contained in the Automated Tropical Cyclone Forecasting (ATCF) system's
working best track. Users are reminded that the best track wind radii represent the maximum
possible extent of a given wind speed within particular quadrants around the tropical cyclone.
As a result, not all locations falling within the swaths will have experienced the indicated
sustained wind speeds.
These data are intended for geographic display and analysis at the national level and for large
regional areas. The data should be displayed and analyzed at scales appropriate for
1:2,000,000-scale data. No responsibility is assumed by the National Oceanic and Atmospheric
Administration in the use of these data.

STORMID
A unique character string that is specific to each tropical cyclone.
The string follows the pattern BBNNYYYY, where BB is AL for Atlantic, EP for East Pacific,
and CP for Central Pacific; NN is the sequential number of the storm during the season;
and YYYY is the year.
BASIN
The ocean where the tropical cyclone is located
AL
Atlantic
EP
East Pacific
STORMNUM
The sequential number of the tropical cyclone for a particular BASIN according
to the time that the first advisory is issued.
STARTDTG
The time and date at which a tropical cyclone first has winds of at least
tropical storm force. This is the date and time at the beginning of the wind swath.
ENDDTG
The time and date of the latest advisory for tropical cyclones that are
still active. For tropical cyclones that no longer exist, ENDDTG is the time and date
in the best track when the system was last designated as a tropical cyclone.
