About HurriTracker
A faster, cleaner way to follow tropical storms: one permanent page per storm, from its first advisory to its archive.
What this site is
HurriTracker maps every active hurricane and tropical storm in the Atlantic and the eastern and central Pacific from official advisories, and keeps the track and history of 3,804 named storms worldwide since 1980. It is an independent site. It does not make its own forecasts and does not issue warnings.
Data sources
- NOAA National Hurricane Center (NHC) and Central Pacific Hurricane Center (CPHC): active storm positions, public advisories, forecast discussions (including their Key Messages, quoted verbatim), forecast cones, tracks, wind fields and coastal watches and warnings. US government work in the public domain.
- IBTrACS v04r01, NOAA National Centers for Environmental Information: historical best tracks for every basin since 1980. Knapp, K. R., M. C. Kruk, D. H. Levinson, H. J. Diamond, and C. J. Neumann, 2010: The International Best Track Archive for Climate Stewardship (IBTrACS): Unifying tropical cyclone best track data. Bulletin of the American Meteorological Society, 91, 363–376.
- GeoNames (CC BY 4.0): place names and coordinates for the distance tool, alerts and landfall locations.
- OpenStreetMap contributors, served as vector tiles by OpenFreeMap: the base map.

How the numbers are made
- Updates. We check NHC for new advisories every five minutes. If a storm page has not received a new advisory for more than seven hours, it says so prominently.
- Winds are 1-minute maximum sustained winds in knots, converted and rounded to the nearest 5 mph or 5 km/h exactly as NHC does, so our numbers match the official text. For basins where only 10-minute winds exist, the archive converts them with a factor of 0.88.
- Categories use the Saffir-Simpson scale for every basin so storms compare worldwide; national scales may differ.
- Storm history paragraphs are generated from best-track data with fixed templates; no numbers are rewritten or estimated.
- Distance and arrival estimates are great-circle distances from the storm’s center, with timings interpolated along NHC’s forecast track. They are rough guidance only.
Editorial and corrections policy
- Official numbers only. Positions, winds, pressures, forecasts, watches and warnings come from the agencies’ own products. We never adjust them, and we never publish our own forecast.
- Quoted, not rewritten. Safety wording such as NHC’s key messages and advisory headlines is quoted verbatim with a link to the source. Nothing on a storm page is written by an AI model.
- Freshness is shown, not hidden. Every storm page names the advisory it is based on and when it was issued, and flags data older than seven hours.
- Corrections. If a page shows something that doesn’t match the official source, email us with the page link. We fix data errors at the source of the problem (the parser or import), so every affected page is corrected, and reply once it’s done.
