The US National Hurricane Center (NHC) said Beryl — currently churning in the Atlantic Ocean about 595 miles (955 kilometers) east of Barbados — would become a “dangerous major hurricane” by the time it reached the Windward Islands late Sunday into Monday.
Barbados, St Lucia, St Vincent and the Grenadines, and Grenada were all under hurricane warnings, while tropical storm warnings or watches were in effect for Martinique, Tobago and Dominica, the NHC said in its latest advisory.
In the Barbadian capital Bridgetown, cars were seen lining up at gas stations, while supermarkets and groceries stores were crowded with shoppers buying food, water and other supplies. Some households were already boarding up their properties.
A major hurricane is considered a Category 3 or higher on the Saffir-Simpson scale, with winds of at least 111 miles per hour.
Such a powerful storm forming this early in the Atlantic hurricane season — which runs from early June to late November — is extremely rare, experts said.
“Only five 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,” hurricane expert Michael Lowry posted on social media platform X.
The NHC said as of Saturday night Beryl’s maximum sustained winds had increased to 85 mph with higher gusts.
“Hurricane conditions are expected in the hurricane warning area beginning Sunday night,” it said, warning of heavy rain, flooding, and “life-threatening winds and storm surge” that could raise water levels as much as seven feet (2.1 meters) above normal.
“Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater,” the NHC said.
The Saffir-Simpson wind scale designates Category 1 hurricanes as having wind speeds at least 74 miles per hour, up to Category 5 storms with winds of 157 mph or higher.
The US National Oceanic and Atmospheric Administration said in late May that it expects this year to be an “extraordinary” hurricane season with up to seven storms of Category 3 or higher.
The agency cited warm Atlantic ocean temperatures and conditions related to the weather phenomenon La Nina in the Pacific for the expected increase in storms.
In recent years, extreme weather events including hurricanes have become more frequent and more devastating as a result of climate change.
