Beryl, the first named hurricane of the season, is due to make landfall on a number of Caribbean islands late on Sunday.
The major storm is growing in strength as it moves across the Atlantic Ocean towards the Caribbean islands of Barbados, Dominica, Grenada and Martinique, among others.
Across the region, people are boarding up their homes, queueing for fuel at gas stations and stockpiling supplies and water in preparation for the storm.
In an address to the nation on Saturday night, the prime minister of Barbados urged residents to look out for their friends, family and neighbours when the hurricane lands.
Forecasters say that Hurricane Beryl, which formed Friday night, has the potential to grow into a Category 3 storm as it moves from the Caribbean into the Gulf of Mexico in the coming days.
They predict that by the time the storm reaches the Windward Islands – made up of Dominica, Martinique, St. Lucia, St. Vincent and the Grenadines and Grenada – there will be “hurricane-force” winds, a “life-threatening” storm surge and heavy rainfall.
Beryl is the second named storm of the season after Tropical Storm Alberto, which made landfall in northeast Mexico on 20 June. The heavy rains of that storm killed four people.
Barbados’ meteorological service issued warnings of power outages and flash flooding, as the eye of the hurricane is expected to pass about 26 miles (45 km) south of the island.
The storm is expected to drop up to six inches (15cm) of rain on Caribbean islands including Barbados.
People are boarding up their homes and thronging supermarkets and petrol pumps in the Barbadian capital of Bridgetown.
“We remain absolutely vigilant and need to take every precaution that is possible for ourselves, for our family and for our neighbours,” Barbadian Prime Minister Mia Motley said on Saturday.
In St Vincent and the Grenadines, prime minister Ralph Gonsalves urged the owners of supermarkets and gas stations to extend their opening hours before the arrival of the hurricane, adding emergency shelters would open on Sunday evening.
Meanwhile, in a briefing shared online by the Government of Dominica, meteorologist Ithoma James urged residents to be prepared, warning hurricanes can be “devastating”.
Hurricane season, which runs from 1 June to 30 November, is predicted to be a busy one this year, according to forecasters.
The National Oceanic and Atmospheric Administration (NOAA) issued its most startling warning to date about the current season. Forecasters said there could be up to 25 named storms in 2024.
Between eight and 13 of those storms could develop into hurricanes, NOAA said.
Anywhere from four to seven of those storms could strengthen into Category-3 or more severe hurricanes. That would be more than double the usual number.
If Hurricane Beryl continues on the trajectory some forecasters are predicting and it develops into a Category 3 storm, the second named storm of the 2024 season would be one of the earliest arrivals of one of the storms the NOAA warned of.
“It’s astonishing to see a forecast for a major (Category 3+) hurricane in June anywhere in the Atlantic, let alone this far east in the deep tropics,” Michael Lowry, a hurricane expert said on social media.
“Only 5 major (Category 3+) hurricanes have been recorded in the Atlantic before the first week of July. Beryl would be the sixth and earliest this far east in the tropical Atlantic.”
In the 2023 hurricane season there were 19 named storms.
