East Pacific Tropical Storm Best Tracks
This is a list of East Pacific hurricanes since 1949. Provided are charts on
the track of the storm plus a text based table of tracking information. The
table includes position in latitude and longitude, maximum sustained
winds in knots, and central pressure in millibars.

NOTE:The East Pacific Best Tracks File is an comma separated ASCII (text) file containing the 6-hourly (0000, 0600, 1200, 1800 UTC) center locations (latitude and longitude in tenths of degrees) and intensities (maximum 1-minute surface wind speeds in knots and minimum central pressures in millibars) for all Tropical Storms and Hurricanes from 1949 through 2021. More information on this file is found on the NHC website.
