About StormTracking
StormTracking is built and run by Dave Maher, a sailor who got tired of stitching together half a dozen government pages every time weather threatened a passage. Sailors read forecasts differently — when the answer matters, you go to the primary source. That's the site's founding rule: every number here comes from an official government feed, refreshed automatically, presented on one page, with nothing editorialized in between.
The site tracks live tropical systems with official NHC forecast cones, severe weather and winter alerts across the US and Canada, and an eleven-year storm archive — free, with no accounts and no tracking of you.
Where every data point comes from
| Layer | Source | Update cadence |
|---|---|---|
| Active storm positions & intensity | NOAA National Hurricane Center (CurrentStorms) | Every 10 min (NHC advisories every 3–6 h) |
| Forecast cones & tracks | NHC official GIS products | Each advisory |
| US watches & warnings | National Weather Service alerts API | Live + 10-min server cache |
| Canadian alerts (incl. maritime) | Environment and Climate Change Canada (GeoMet) | Every 10 min |
| Development outlook | NHC Tropical Weather Outlook | Every 10 min (issued 4×/day) |
| Storm archive (2015–present) | NOAA HURDAT2 best track + live season data | Annual revision + live |
| Radar | NWS NEXRAD via Iowa Environmental Mesonet | ~5 min |
| Satellite | NOAA GOES-East GeoColor via NASA GIBS | Near-real-time |
Methodology notes
- Storm history pages count a storm as affecting a state when a NOAA best-track point with winds ≥ 34 kt falls inside the state's borders — offshore passes with onshore impacts may not appear.
- Winter "events" are automated groupings of official alerts by region; the NWS does not name winter storms.
- Archive records cover 2015–present, Atlantic and East Pacific basins, systems that reached tropical-storm strength.
Citing StormTracking
<a href="https://stormtracking.com">StormTracking</a> — deep links to storm pages, seasons, and records are stable and encouraged. The underlying NOAA/ECCC data is public domain; our compilations and pages are free to cite with a link.Journalists: the record book, season archive, and per-storm pages are built for citation — every figure traces to NOAA best-track or live advisories. Embeddable widgets and data feeds are on the share page.

The important caveat
StormTracking is an independent aggregator, not an official warning source. For decisions that could affect life or property, rely on weather.gov, hurricanes.gov, weather.gc.ca, and local emergency management.
