Havana, Cuba (CNN) Hurricane Irma, which devastated much of the Caribbean in September, has claimed a new victim: Raul Castro's succession plans. On Thursday, Cuban officials said the island was still dealing with the aftermath of the killer storm and needed to postpone long-held plans for Castro, 86, to retire on February 24, 2018, when his second five-year term ends. It was to have been the first time that Cuba was ruled by a leader not named Castro since the 1959 revolution that swept Raul Castro's older brother Fidel Castro to power. The wrath of Irma, however, delayed the Communist-run island's single party elections process, which appoints the Cuban National Assembly that in turn selects Cuba's president.Cuba, dealing with Hurricane Irma aftermath, says Castro will retire in April instead of FebruaryCastro has indicated first Vice President Miguel-Diaz Canel has his blessing to be the next president 
 Question:"My second and last term will have concluded," _ told Cuban lawmakers on Thursday, "and Cuba will have a new president."
