With maximum sustained winds of 185 mph (295 kph), recorded by the U.S. National Hurricane Center, the Category 5 Hurricane Irma is feared to be the most catastrophic storm ever. On Wednesday the storm will hit Puerto Rico, the Dominican Republic, Haiti on Friday, and Cuba on Saturday before possibly reaching Florida over the weekend. There is great apprehension in the United States if Irma reaches south to the Gulf of Mexico, it would break into the coasts of Florida, while in Texas and Louisiana they are still counting on the devastating floods caused by Hurricane Harvey.

Many cruise voyages in the Caribbean have been impacted by Irma, including Royal Caribbean, Carnival, Norwegian Cruise Line, Disney and MSC cruise ships.
