Data Sources

NOAA HURDAT2 — Historical best-track data (1991–present) for storm tracks, wind speeds, and ACE calculations
NHC Real-time Best Track — Current season preliminary storm data fetched via Tropycal (include_btk=True); updated continuously during active storms
NOAA CPC — Season classification thresholds and 1991–2020 climatological normals

ACE (Accumulated Cyclone Energy) is calculated at 6-hourly synoptic times (0000/0600/1200/1800 UTC) for systems with status TS, HU, or SS and wind ≥34 kt — extratropical (EX) phases are excluded per NHC methodology. Formula: ACE = Σ(V²_max) × 10⁻⁴. Categories use the Saffir-Simpson scale in knots.

Basin note: The East & Central Pacific tab combines both the Eastern Pacific (NHC, east of 140°W) and Central Pacific (CPHC, 140°W–180°) basins, consistent with the NOAA HURDAT2 Northeast & North Central Pacific dataset. NHC tracks these separately on their TCR pages (epac / cpac).

⚠️ This site is maintained by a hurricane data enthusiast — not a meteorologist, forecaster, or weather professional of any kind. I just love the data. All information is sourced directly from official NOAA/NHC databases. For official forecasts, watches, warnings, and life-safety information, always refer to the National Hurricane Center.

Page built September 27, 2026 at 03:21 UTC. The data-as-of line above each basin's numbers shows how current the storm data is.
