Historic, life-threatening flash flooding and landslides are expected in portions of Jamaica, southern Haiti and the Dominican Republic through the weekend, the NHC said. Peak storm surge heights could reach 9 to 13 feet above normal tide levels when the storm makes landfall, accompanied by large and powerfully destructive waves.

Melissa is not expected to make landfall in Florida or the U.S. The powerful storm is expected to make landfall on the island nation of Jamaica Tuesday morning. At 8 p.m., Melissa has maximum sustained winds of 175 mph and gusts of well over 200 mph. Melissa is a dangerously powerful Category 5 hurricane.

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.

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.

According to the National Hurricane Center's 8 a.m. Tuesday advisory, Category 5 Hurricane Melissa is in the Caribbean Sea, 55 miles south-southeast of Negril Jamaica and 265 miles southwest of Guantanamo Cuba. With maximum sustained winds of 175 mph, the hurricane is moving to the north-northeast at 7 mph.

Will the 13th storm of the hurricane season be lucky and pass right over, or will it be the first to make landfall, potentially in Florida?

"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.
