Hurricane Melissa remains a powerful Category 5 storm with winds of 175 mph that is forecast to slam into Jamaica as the worst storm the island has ever seen.Here is Melissa’s forecast path:  Hurricane Melissa live updates: Storm upgraded to Category 5 on approach to JamaicaThe catastrophic and life-threatening hurricane-force winds will begin in Jamaica on Monday night.

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.

The news “underscores the profound ecological toll that Hurricane Melissa will have on Jamaica’s biodiversity,” said one expert on the island.

Melissa could briefly bring a swell and rough seas to the U.S. East Coast after it passes the Bahamas later in the week, but because of the angle and speed at which it's moving off into the Atlantic, Roth said any coastal impacts should be short-lived.

Melissa has already killed three people in Haiti and Jamaica each and one person in the Dominican Republic. United Nations staff are preparing to deploy to Cuba and Jamaica this week as the region nervously awaits landfall of Hurricane Melissa.
