METHODOLOGY

Data sources and limitations

The map and totals are generated from NOAA’s IBTrACS v04r01 archive. A storm belongs to this page when the archive lists it in the North Atlantic basin for the 2017 season, so a December storm whose track ends in January stays with its season. Storms that cross between basins appear on the page of their archive basin only.

Counts use US-agency one-minute winds during the tropical stage: 34 kt for a tropical storm, 64 kt for hurricane strength and 96 kt for major intensity, on the Saffir–Simpson scale in every basin. Local agencies classify storms differently, and official season summaries can differ from the archive. Accumulated cyclone energy sums squared winds at six-hourly synoptic times, counting observations in the calendar year. Storms with no US-agency wind are mapped but cannot enter the counts.

The map frame is the same for every North Atlantic season, so a track that leaves it is cut at the edge. Lines show each storm’s center, not its size, rainfall or flood extent. Coastlines use Natural Earth’s 1:10m land data.
