Michael Brennan, director of the U.S. National Hurricane Center in Miami, said late Tuesday that winds across Jamaica would remain dangerous even though Hurricane Melissa's center had moved into open water.

He said people in Jamaica are still facing "dangerous conditions across the island."

Hurricane Melissa made landfall on Jamaica as the strongest storm to hit the Caribbean island since records were first kept 174 years ago. It is tied for the strongest Atlantic hurricane to ever hit land.

Melissa is a Category 5 storm with sustained wind speeds of 185 mph.

Melissa is now headed toward the southeast coast of Cuba, where it was expected to make landfall as a major hurricane early Wednesday.

The storm was expected to generate a storm surge of up to 12 feet in the region and drop up to 20 inches of rain in parts of eastern Cuba.

"Numerous landslides are likely in those areas," Brennan said.

Cuban President Miguel Díaz-Canel said every effort will be made to protect residents despite the fragility of the island's economy.

In a televised address to the nation and wearing an olive-green uniform, Díaz-Canel urged the population to not underestimate the power of the storm, calling it "the strongest ever to hit national territory."

He asked residents to avoid bathing in swollen rivers and urged them not to leave evacuation sites "until the order has been given."

"There will be a lot of work to do. We know there will be a lot of damage."

Officials in Jamaica are warning the public in the capital, Kingston, and surrounding areas to beware of crocodiles and avoid floodwaters.

"Heavy rains and flooding associated with Hurricane Melissa may result in crocodiles being displaced from their natural habitats," said the island's South East Regional Health Authority in an official social media post.

It warned people to not try and capture or harm any crocodile "that appears displaced."

The only species of crocodile in Jamaica is found primarily along the island's southern coast from St. Thomas to Westmoreland. Smaller populations may be found in Hanover and Trelawny, according to Jamaica's National Environment and Planning Agency.

China's ambassador to Cuba posted a video on X showing the transportation of hundreds of boxes of what he called "family kits," along with pictures of their contents: footwear, toothbrushes, forks, spoons, bowls, umbrellas and thermal blankets, among others.

"The damage is expected to be considerable," Hua Xin wrote.

The products were pre-positioned in eastern Cuba ahead of the hurricane and were delivered by the Chinese Red Cross to its Cuban counterpart.

People in Santiago de Cuba, the island's second-largest city with more than one million inhabitants, spent Tuesday frantically preparing for Melissa.

Few people were on the streets, while state television showed Cubans in rural areas rounding up animals and protecting crops.

"This is coming with more power than (Hurricane) Sandy. We'll see what happens," Miguel León, 60, told The Associated Press as he recalled one of the most damaging storms to hit the city in 2012.

Diamon Mendoza, 36, did not hide her concern about the unavoidable storm.

"May God have mercy on us, because it's coming with a lot of strength," Mendoza said. "Anything can happen."

Experts say Hurricane Melissa's 185 mph winds and 892 millibars of central pressure on landfall tied two different records for the strongest Atlantic storm upon hitting land.

The pressure measurement — the key one meteorologists use — ties with 1935's Labor Day hurricane in Florida. And the wind speed ties with that 1935 hurricane and 2019's Hurricane Dorian. That's according to hurricane scientists Philip Klotzbach of Colorado State University and Brian McNoldy of the University of Miami.

"It's been a remarkable, just a beast of a storm," Klotzbach told The Associated Press.

Melissa is the strongest Atlantic hurricane to make landfall since Hurricane Dorian made landfall on Abaco Island in the Bahamas in 2019 with 185 mph winds. That's according to Philip Klotzbach, a Colorado State University hurricane researcher.

Hurricane Melissa has made landfall in Jamaica as a Category 5 storm, the strongest direct hit to the island in 174 years.

Melissa is the strongest hurricane to make landfall in Jamaica since record-keeping began in 1851. That's according to Jamaica's Meteorological Service and other experts.

Authorities in the eastern Cuban province of Holguín prepared to evacuate more than 200,000 people on Tuesday, in addition to a similar number moved to safety from the town of Banes.

Reports on social media and state television showed blue-and-white buses ferrying evacuees to shelters. Families clutched babies and belongings, and elderly people steadied themselves with canes as they disembarked.

"This phenomenon is very dangerous," Deputy Prime Minister Eduardo Martínez said in a statement from Banes, where he was located in what appeared to be a shelter. "It is unprecedented," he said of Hurricane Melissa.

"It's going to be a very dangerous scenario," said Michael Brennan, director of the U.S. National Hurricane Center in Miami, warning that there would be "total building failures."

Brennan said Jamaica's highest mountains could see wind gusts of up to 200 mph.

"It's just a catastrophic situation playing out here for Jamaica," he said.

Brennan noted that Melissa would make landfall in eastern Cuba overnight Tuesday or early Wednesday.

As Jamaica shut down before landfall, one of the island's main radio stations played uplifting songs, including a new reggae jam that referenced Melissa.

"Hold on, Jamaica!" the singer crooned as he gave a shout-out to all those in the Caribbean affected by the storm, "our family in Cuba, our sisters in Haiti."

In between songs, people called in and reported conditions in their neighborhoods, with one woman in western Jamaica saying it sounded like someone was knocking heavily on her door.

"Jamaica, this is not the time to be brave," said Desmond McKenzie, deputy chairman of Jamaica's Disaster Risk Management Council.

McKenzie said the government was prepared for potential rescues immediately after the storm.

"We have boats, helicopters, you name it," he said.

The British government says it is ready to deliver humanitarian aid to Jamaica if requested, as the Caribbean nation braces for the impact of Hurricane Melissa.

Foreign Secretary Yvette Cooper said she spoke to her Jamaican counterpart Kamina Johnson Smith "to offer the U.K.'s full support and solidarity, and we are prepared to mobilize resources at their request."

Cooper said the government is "positioning specialist rapid deployment teams to provide consular assistance to British nationals in the region."

There are thought to be thousands of U.K. nationals in Jamaica, a combination of vacationers and people visiting relatives. The Foreign Office urged Britons to register their presence through an online portal to get updates from the British government.

The U.N.'s International Organization for Migration said Tuesday that it is dispatching solar lamps, blankets, indoor tents, generators and other items from its logistics hub in Barbados to Jamaica as soon as the storm crosses the island.

"Many people are likely to be displaced from their homes and in urgent need of shelter and relief," said Natasha Greaves, interim head for IOM Jamaica.

Meanwhile, the nonprofit Direct Relief said it has two packages with enough medications to treat 3,000 people in one month staged in Panama and ready to deploy to Jamaica.

It also will send a shipment of 100 field medic packs from its warehouse in California to Jamaica as soon as the island's main international airport reopens.

Officials in Jamaica say they are concerned that not enough people are seeking shelter as the catastrophic storm approaches.

More than 130 shelters were open across the island, but by late Monday, fewer than 1,000 people had heeded evacuation orders.

One exception was the small community of Old Harbor, just west of Kingston. Some 200 people crowded in its shelter by late Monday.

"It's definitely more than last time," said Jason Fuller, a firefighter and shelter volunteer, referring to the number of people that sought shelter from Hurricane Beryl last year.

He said the team of volunteers have ensured that there is adequate food, bedding and security with police and soldiers on location.

In the past, Jamaicans have complained about the safety in shelters and lack of basic goods.

"I am feeling safe and OK," said a cheerful 13-year-old girl who only provided her first name, Natanya.

On Tuesday morning, Melissa was centered about 55 miles south-southeast of Negril, Jamaica, and about 265 miles southwest of Guantánamo, Cuba. The system had maximum sustained winds of 175 mph and was moving north-northeast at 7 mph, according to the U.S. National Hurricane Center in Miami.

Colin Bogle, a Mercy Corps advisor based near Kingston, said most families are sheltering in place despite the government ordering evacuations in flood-prone communities.

Melissa also is expected to make landfall in eastern Cuba late Tuesday as a powerful hurricane. Cuban officials said Monday that they were evacuating more than 600,000 people from the region, including Santiago, the island's second-largest city.
