Nine Category 5 Storms In 2015 - 2nd Highest Global Total On Record

Category Five: the phase evokes an almost reverential awe in novice and seasoned hurricane watchers alike, as one considers the incredible power and majesty of these most perfect but terrifyingly destructive storms on the planet. As we look back on the year in weather, a striking feature of 2015 is the bumper crop of these fearsome storms that appeared--thanks to El Niño bringing record-warm ocean temperatures to large swaths of the Pacific Ocean. Nine Category 5 storms whipped into life over the world's oceans in 2015: five in the Northwest Pacific, one in the Northeast Pacific, one in the Southeast Pacific, and two in the South Indian Ocean. Since accurate global satellite records began in 1990, only one year has seen more. That record is held by the El Niño year of 1997, which had twelve Category 5 storms--ten of them in the Northwest Pacific. Two other season have seen nine Cat 5s--2004 and 2014. Earth averaged just 4.6 Category 5 storms per year between 1990 - 2014, according to ratings made by NOAA's National Hurricane Center and the U.S. Navy's Joint Typhoon Warning Center. The majority of these storms occur during the July - November peak of the Northern Hemisphere's tropical cyclone season, with 59% of all Cat 5s occurring in the Northwest Pacific.
