Every hurricane and cyclone detected since 1842

This map shows the paths of every hurricane and cyclone detected since 1842 -- nearly 12,000. NOAA keeps the track info in a single database, and made this map which shows the frequency of the storms. You can clearly see that more storm tracks have overlapped in the western Pacific ocean and northern Indian ocean. This is largely because of the length of the typhoon season, which basically never stops in the warmer waters there. NOAA also mapped the storm intensities.
