How these numbers are made
From NOAA’s best tracks (HURDAT2), every storm’s centre is followed hour by hour and measured against each place; a season counts once it had a tropical storm or hurricane within 100 miles (or 50) on at least one day. It is history, not a forecast: for a storm that exists today, read the National Hurricane Center.
