TROPICAL STORM TRACKS DATABASE
The storm tracks database is derived from the storm data

Hurricane Center (NHC). This web page provides a convenient user
interface for casually browsing storm information, including location,
category, and wind speed.
Information about the underlying services which provide this information may
be found here. These services
are available to anyone.
The bulk of the information in this database is derived from
the storm data provided annually by the National Hurricane Center (NHC) in
HURDAT format. The HURDAT file contains Atlantic basin storms from 1851 to the
previous storm season and Eastern and Central Pacific storms from 1949 to the
previous storm season, but it is not updated during the current storm season.
We also download and process data for ongoing storms during
storm season (roughly April to January). These data are constantly updated
in the database while there are active storms at roughly six-hour intervals.
Storm information may be browsed in two ways, using the "quick"
search, or the "advanced" search which allows more detailed specification of
