 A few months later , on April 9 , 2015 , TSR updated its report , detailing its prediction of activity 45 % below the 1950 – 2014 average , or about 50 % below the recent 2005 – 2014 average , with 11 named storms , 5 hurricanes , 2 major hurricanes , and a cumulative ACE index of 56 units . TSR cited what were expected to be cooler than average ocean temperatures across the tropical North Atlantic and Caribbean Sea as reasoning for lower activity . In addition , the report stated that if the ACE forecast for 2015 were to verify , the total values during the three @-@ year period from 2013 – 2015 would be the lowest since 1992 – 1994 , signalling a possible end to the active phase of Atlantic hurricane activity that began in 1995 .
