Celebrity Beyond’s Oct. 26 itinerary will visit the Western Caribbean rather than the Eastern Caribbean, according to the cruise line’s parent company, Royal Caribbean Group. The ship will visit Costa Maya in Mexico, Belize and Roatan, Honduras.

"It is more than kind of distressing because you don't know when and you don't know how," said Ewan Simpson, who lives in Jamaica.

As Category 5 Hurricane Melissa threatens multiple Caribbean islands with a projected path to make landfall in Jamaica by Oct. 28 before continuing on through Cuba, The Bahamas, and Turks and Caicos, Carnival and other cruise lines have made major changes to this week’s Caribbean cruise routes.

Caribbean Disaster Relief Fund of Minnesota and the Jamaica Minnesota Organization are two of the groups working to provide help.

Jamaica is expected to be in the storm's eyewall, which refers to the band of dense clouds surrounding the eye of the hurricane. The eyewall generally produces the fiercest winds and heaviest rainfall, according to Deanna Hence, a professor of climate, meteorology and atmospheric sciences at the University of Illinois Urbana-Champaign.

Melissa is a deadly Category 5 hurricane and is expected to become to worst hurricane in Jamaica's history before it travels north to Cuba.
