Hurricane Beryl nears Caribbean islands as

Hurricane Beryl was closing in on the Windward Islands in the southeast Caribbean as an “extremely dangerous” Category 4 storm, the National Hurricane Center said Sunday night. Forecasters warned the first major hurricane of the Atlantic season would bring life-threatening winds and storm surge to the Windward Islands early Monday.

Hurricane warnings are already in effect in Barbados, St. Lucia, Grenada, St. Vincent and the Grenadines and Tobago. Tropical storm warnings are in effect for Martinique and Trinidad, while a tropical storm watch is in effect in Dominica, the south coast of the Dominican Republic from Punta Palenque westward and the south coast of Haiti from the Dominican border to Anse d’Hainault. 

“This is a very serious situation developing for the Windward Islands,” warned the Miami-based National Hurricane Center. The center said that Beryl was “forecast to bring life-threatening winds and storm surge … as an extremely dangerous hurricane.”

Beryl is on track to move across the Windward Islands early on Monday before traveling through the southeastern Caribbean on Monday night and Tuesday.

Two hurricane hunters were en route to the storm to gather more details about its intensity, according to the National Hurricane Center.

Historic hurricane

It took Beryl only 42 hours to strengthen from a tropical depression to a major hurricane — a feat accomplished only six other times in Atlantic hurricane history, and with Sept. 1 as the earliest date, according to hurricane expert Sam Lillo.

Beryl is now only the third Category 3 hurricane ever recorded in the Atlantic in June, following Audrey in 1957 and Alma in 1966, hurricane specialist and storm surge expert Michael Lowry said.

“Beryl is an extremely dangerous and rare hurricane for this time of year in this area,” he told the Associated Press in a phone interview. “Unusual is an understatement. Beryl is already a historic hurricane and it hasn’t struck yet.”

Hurricane Ivan in 2004 was the last strongest hurricane to hit the southeast Caribbean, causing catastrophic damage in Grenada as a Category 3 storm.

“So this is a serious threat, a very serious threat,” Lowry said of Beryl.

Beryl is the second named storm in what is predicted to be a busy hurricane season, which runs from June 1 to Nov. 30 in the Atlantic. Last week, Tropical Storm Alberto brought torrential flooding to portions of southern Texas and northeastern Mexico. It was responsible for at least four deaths in the Mexican states of Nuevo Leon and Veracruz.  

According to CBS News weather producer David Parkinson, Beryl is the farthest east a hurricane has formed in June, and one of only two to do so east of the Caribbean, with the other instance occurring in 1933. Parkinson expects Beryl to remain south of Jamaica, and forecasts that any U.S. impacts are still at least eight days away. 

Warm waters are fueling Beryl, with ocean heat content in the deep Atlantic the highest on record for this time of year, according to Brian McNoldy, University of Miami tropical meteorology researcher.

Forecasters warned of a life-threatening storm surge of up to 9 feet in areas where Beryl will make landfall, with up to 6 inches of rain for Barbados and nearby islands.

Bracing for the storm

Long lines formed at gas stations and grocery stores in Barbados and other islands as people rushed to prepare for a storm that rapidly intensified from a tropical storm with 35 mph winds on Friday to a Category 1 hurricane on Saturday.

“We need to be ready,” Barbadian Prime Minister Mia Mottley said in a public address late Friday. “You and I know when these things happen, it is better to plan for the worst and pray for the best.”

She noted that thousands of people were in Barbados Saturday for the Twenty20 World Cup cricket final, with India beating South Africa on Saturday in the capital of Bridgetown. It is considered cricket’s biggest event.

Meanwhile, St. Vincent and the Grenadines Prime Minister Ralph Gonsalves said in a public address Saturday that shelters will open Sunday evening as he urged people to prepare. He ordered officials to refuel government vehicles and asked grocery stores and gas stations to stay open later before the storm.

“Please take this very seriously and prepare yourselves,” said Gonsalves. “This is a terrible hurricane.”

Caribbean leaders were preparing not only for Beryl, but for a cluster of thunderstorms trailing the hurricane that have a 70% chance of becoming a tropical depression.

“Do not let your guard down,” Mottley said.

According to the National Hurricane Center, the season’s first hurricane usually forms in early to mid-August, which makes Beryl unusual for having reached hurricane strength so early in the summer. In a report released last month, the National Oceanic and Atmospheric Administration predicted an “above average” hurricane season with 17 to 25 storms, 8 to 13 hurricanes and 4 to 7 major hurricanes of category 3 or higher. An average Atlantic hurricane season produces 14 named storms, seven of them hurricanes and three major hurricanes.

A tropical storm is named when a tropical cyclone has maximum sustained winds of 39 to 73 mph, while a hurricane is defined as a tropical cyclone with maximum sustained winds greater than 74 mph.
