Sources. Storm tracks and events from NOAA's best-track archives, exactly as the Hurricane Calendar app shows them. Dates are calendar dates in UTC. Each wind speed keeps the agency that recorded it and its averaging period; nothing is converted between agencies. A missing value is shown as not recorded, never as zero. Storms that may still have been active when the archive was updated are left out.
