About Hurricanes
Hurricanes (tropical cyclones) are powerful rotating storm systems that form over warm ocean waters and can bring extreme winds, storm surge, torrential rain, and inland flooding. The Atlantic hurricane season runs June 1 through November 30, while the eastern Pacific season runs May 15 through November 30. Major landfalling hurricanes can affect areas hundreds of miles from the storm center.
Data Source
Active storm data comes from the NHC's official GIS products, updated with each advisory (every 6 hours, or every 3 hours for storms near land). Historical track data is sourced from the HURDAT2 best-track dataset, the definitive archive of Atlantic and eastern Pacific tropical cyclones maintained by NOAA's Atlantic Oceanographic and Meteorological Laboratory.

What the Map Shows
Active named tropical storms and hurricanes with their current positions, intensity (Category 1–5 or tropical storm), and forecast tracks. Historical tracks for major Atlantic and Pacific storms are also displayed for reference. Forecast cone polygons indicate the probable path of the storm center, not the extent of dangerous conditions.
