The data in this viewer was updated on June 15th, 2021 to include HURDAT2 data and NHC ATCF model data through the end of 2020 for the Atlantic, East Pacific and Central Pacific. That means data is complete through 2020. The data will likely not be updated again, to add 2021 data, until mid-2022. This project remains under construction (work will likely resume in 2022). It is highly experimental. It is based on the NOAA viewer here. Add too much data and it will crash your browser. It does not yet update in real time. Among possible things left to add: Various options on line color, line size and point size, various updates to the layout of the display, save a link to current view, storm specific options, export data to Google Earth or GeoJSON file, save screenshot and select your coordinates on the map.
