KINGSTON, Jamaica — Hurricane Beryl was roaring by Jamaica Wednesday, bringing fierce winds and heavy rain after the powerful Category 4 storm earlier killed at least six people and caused significant damage in the southeast Caribbean.

The U.S. National Hurricane Center said Beryl’s eyewall was “brushing the south coast of Jamaica.”

Wind-whipped rain pounded the island for hours as residents heeded authorities’ call to shelter until the storm had passed. Power was knocked out in much of the capital.

Prime Minister Andrew Holness said on Wednesday afternoon that nearly 500 people were placed in shelters.

“We are placing emphasis on ensuring they are comfortable and well looked after,” he said in a social media post.

Before Beryl’s arrival in Kingston, people had earlier boarded up windows, fishermen pulled their boats out of the water and workers dismantled roadside advertising boards to protect them from the lashing winds.

Kingston resident Pauline Lynch said that she had stockpiled food and water in anticipation of the storm’s arrival. With wind already driving rain, Lynch said, “I have no control over what is coming so I just have to pray that all people of Jamaica is safe and we don’t suffer no deaths, no loss.”

By midday, winds already howled in the capital, turning the sea into churning whitecaps as Beryl’s eye scraped by the island’s southern coast.

“We are very concerned about a wide variety of life threatening impacts in Jamaica,” including storm surge, high winds and flash flooding, said Jon Porter, chief meteorologist at AccuWeather.

Porter called Beryl “the strongest and most dangerous hurricane threat that Jamaica has faced, probably, in decades.”

A hurricane warning was in effect for Jamaica, Grand Cayman, Little Cayman and Cayman Brac. Beryl was forecast to weaken slightly over the next day or two, but still be at or near major-hurricane strength when it passes near or over Jamaica on Wednesday, near the Cayman Islands on Thursday and into Mexico’s Yucatan Peninsula on Friday, according to the U.S. National Hurricane Center.

Jamaica was under a state of emergency as the island was declared a disaster zone hours before the impact of Hurricane Beryl.

Holness said that the disaster zone declaration will remain for the next seven days. He also announced an island-wide curfew between 6 a.m. and 6 p.m. on Wednesday.

Security forces “will be fully mobilized to maintain public order and assist with disaster relief. As soon as the hurricane has passed, the security forces have developed strategic plans to counter any potential threat of looting or any other opportunistic crimes,” Holness warned.

An evacuation order was also issued for communities across Jamaica that are prone to flooding and landslides. Holness urged Jamaicans to move away from low-lying areas.

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 165 mph Tuesday before weakening to a still-destructive Category 4. On Wednesday, the storm’s center was about 65 miles west-southwest of Kingston. It had maximum sustained winds of 140 mph and was moving west-northwest at 20 mph. Hurricane strength winds extended 45 miles from the center.

The last strong hurricane to hit the southeast Caribbean was Hurricane Ivan 20 years ago, which killed dozens of people in Grenada.
