Windows blown in, trees uprooted and croc warnings - Hurricane Melissa batters Jamaica

Hurricane Melissa is causing havoc in Jamaica as the Caribbean nation faces the strongest storm in its modern history.

The hurricane, now a category four with wind speeds of 150mph (240km/h), is heading towards Cuba and then the Bahamas. Earlier, Melissa made landfall on Jamaica's coastline with winds of more than 185mph.

The US National Hurricane Center said the hurricane is bringing "catastrophic winds, flash flooding and storm surges" while the Meteorological Service of Jamaica said things will get "significantly worse".

Jamaican authorities have urged residents and visitors to continue sheltering, with nearly a third of the country already without power.

Photos showing fallen trees and damaged homes are already emerging from Jamaica since Hurricane Melissa made landfall.

"It's a catastrophic situation," the World Meteorological Organization's tropical cyclone specialist Anne-Claire Fontan told a press briefing, warning of storm surges up to four metres high.

"For Jamaica, it will be the storm of the century for sure."

Roofs have been torn off hospitals, former Jamaican senator Imani Duncan-Price told the BBC.

"People are trying to rescue people in the middle of the storm just to save lives," he said.

Up to 30 inches (76cm) of rain is expected in some parts, with areas already experiencing flash flooding.

Around 70% of the island's 2.8 million population lives within 5km of the sea.

The hurricane and resulting flooding may displace crocodiles from their natural dwellings, Jamaican health officials said.

"Rising water levels in rivers, gullies, and swamps could cause crocodiles to move into residential areas," the South East Regional Health Authority said in a statement.

"Residents living near these areas are therefore advised to remain vigilant and avoid flood waters."

Winston Warren, who says he lives less than 1km from the ocean, described the sound as "a constant roar of water".

"There are times you just wonder - are the waves going to come crashing into your house," he said.

"We've seen a lot of roofs blown off."

One woman told the BBC: "There is water coming in through the roof of my house.

"I am not okay."

The slow-moving storm is forecast to remain a powerful hurricane as it crosses Jamaica, whose highland communities are vulnerable to landslides and flooding.

Even before the eye of the hurricane reached land, countries in the region experienced extreme weather and fatalities.

On Monday, Jamaica's government said three people had died in "storm-related" incidents which involved felling trees.

The storm is heading towards Santiago de Cuba, Cuba's second-largest city.

In Cuba, authorities said they had evacuated about 500,000 people from areas vulnerable to winds and flooding.

"Melissa will arrive with force, and there's great concern about what it could destroy in its wake," Cuban President Miguel Diaz-Canel said in a message published in state newspaper Granma.
