Beryl heads toward Jamaica as major hurricane after ripping through southeast Caribbean

Hurricane Beryl was roaring toward Jamaica on Wednesday, with islanders scrambling to make preparations after the powerful Category 4 storm earlier killed at least six people and caused significant damage in the southeast Caribbean.

In Kingston, people boarded up windows, fishermen pulled their boats out of the water before sitting around a table to play dominoes beside a bay, and workers dismantled roadside advertising boards to protect them from the expected lashing winds to come.

A hurricane warning was in effect for Jamaica, Grand Cayman, Little Cayman, and Cayman Brac. Beryl was losing intensity but was forecast to still be near major-hurricane strength when it passes near or over Jamaica early Wednesday, near the Cayman Islands on Thursday and into Mexico's Yucatan Peninsula on Friday, according to the National Hurricane Center.

A hurricane watch was in effect for Haiti's southern coast and the Yucatan's east coast. Belize issued a tropical storm watch stretching south from its border with Mexico to Belize City.

Late Monday, Beryl became the earliest storm to develop into a Category 5 hurricane in the Atlantic and peaked at winds of 270 kilometres per hour Tuesday before weakening to a still-destructive Category 4.

Early Wednesday, the storm was about 300 kilometres east-southeast of Kingston, Jamaica. It had top winds of 230 km/h and was moving west-northwest at 31 km/h, the centre said.

Beryl was expected to bring life-threatening winds and storm surge to Jamaica, where officials warned residents in flood-prone areas to prepare for evacuation.

"I am encouraging all Jamaicans to take the hurricane as a serious threat," Prime Minister Andrew Holness said in a public address Tuesday. "It is, however, not a time to panic."

In Miami, National Hurricane Center director Michael Brennan said Jamaica appears to be in the direct path of Beryl.

"We are most concerned about Jamaica, where we are expecting the core of a major hurricane to pass near or over the island," he said in an online briefing. "You want to be in a safe place where you can ride out the storm by nightfall [Tuesday]. Be prepared to stay in that location through Wednesday."

Storm surge of 1.8 to 2.7 metres above typical tide levels are likely in Jamaica, as well as heavy rainfall.

"This is a big hazard in the Caribbean, especially with the mountainous islands," Brennan said. "This could cause life threatening flash floods and mudslides in some of these areas."

A tropical storm warning was in place for the entire southern coast of Hispaniola, an island shared by Haiti and the Dominican Republic.

On Tuesday, the Canadian government urged Canadians to avoid travelling to Haiti and other Caribbean nations due to the threat posed by the hurricane.
