Global Tropical System Tracks - April 2023
The following Tropical System tracks are compiled from various centers, but
unless otherwise cited, the data is from the Naval Research Laboratory (NRL)
or from a reanalysis using GRADS. NCEP Reanalysis data provided by the
NOAA/OAR/ESRL PSD, Boulder, Colorado, USA, from their Web site at
http://www.esrl.noaa.gov/psd/.
The data usually does not match the information from the advisories, but is
closer to the Best Track data. However official Best Track data should
be considered the final and official tracks. The data also includes
Investigation areas as well as pre- and post-advisory information
