CNN —
Beryl, the first hurricane of the 2024 Atlantic season, intensified to an extremely dangerous Category 4 hurricane with maximum sustained winds of 130 mph Sunday morning, as it makes its way toward the Windward Islands.
Beryl is now the earliest Category 4 hurricane on record in the Atlantic Ocean and the only Category 4 storm ever recorded in the month of June.
Tropical storm-force winds are expected to reach the Windward Islands late Sunday or early Monday.
The early timing of the season’s first hurricane is unusual, given the average date for the first hurricane is August 11.
As of 11 a.m. ET, Beryl was about 355 miles east-southeast of Barbados, heading west.
Beryl is forecast to be a Category 4 hurricane when it reaches the Windward Islands.
“A life-threatening storm surge will raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore flow near where the eye makes landfall in the hurricane warning area,” the NHC said, adding that the surge could bring large and destructive waves near the coast.
The hurricane is strengthening quickly, increasing 55 mph in the 24 hours before Sunday morning. The National Hurricane Center defines rapid intensification as an increase in maximum sustained wind speed of 35 mph or more in a 24-hour period.
“We’re forecasting rapid intensification and expectingBerylto become a major hurricane before it reaches places like Barbados and the Windward islands and continue to be a powerful hurricane as it moves into the eastern and central Caribbean as we go into the early portions of next week,” Mike Brennan, Director of the National Oceanic and Atmospheric Administration’sNational Hurricane Center, told CNN’sFredricka Whitfield Saturday.
Residents in places with hurricane warnings should be prepared for major storm impacts, Brennan said. Beryl brings a risk of heavy rainfall, destructive hurricane-force winds and dangerous storm surge and waves. Rainfall totals of 3 to 6 inches could bring localized flooding across the Windward Islands Sunday night and Monday, according to the center.
Hurricane warnings are in effect for Barbados, Saint Lucia, Saint Vincent and the Grenadine Islands, Grenada, and Tobago.
The hurricane is expected to produce 3 to 6 inches of rain across Barbados and the Windward Islands through Monday, the weather center said.

The first hurricane of the season is unusually early
Beryl is the earliestmajor hurricane – defined as one that is Category 3 or higher – in the Atlantic in 58 years. The storm’s rapid intensification is very unusual this early into hurricane season, according to Brennan. It’s rare for tropical systems to form in the central Atlantic east of the Lesser Antilles in June, particularly strong ones, with only a handful having done so, according to NOAA records.
Beryl isn’t just early for this hurricane season: It is now the Atlantic Ocean’s third-earliest major hurricane. The earliest was Hurricane Alma on June 8, 1996, followed by Hurricane Audrey, which reached major status on June 27, 1957.
The storm has already set the record for the easternmost hurricane to form in the Tropical Atlantic in June, beating a previous record set in 1933.
The central and eastern Atlantic traditionally become more active in August, in part because ocean temperatures have had time to warm and fuel developing systems.
This year, however, the Atlantic basin has seen above normal water temperatures and a lack of wind shear due to the transition from El Niño season to La Niña season, both of which are fuel for tropical development.
“Berylhas found an environment with very warm ocean waters for this time of year,” Brennan said.
Warmer waters in the Atlantic Basin have given tropical storms and hurricanes the opportunity to develop at a more rapid pace in an more eastward position, according to Brennan, allowing storms to become more powerful and therefore more destructive earlier on in hurricane season, which runs from June 1 until November 30.
“These are ocean water you’d normally see like in August or September, but now we’re seeing them in late June,” Brennan said. “It’s kind of opening up more of the deep tropical Atlantic for formation before we get to what would be the traditional peak of the hurricane season.”
Caribbean islands urge public to prepare ahead of hurricane
Authorities are urging residents to take precautionary measures, with several Caribbean nations under hurricane watches and warnings while HurricaneBerylapproaches and gains strength.
Officials in Barbados say the island is expected to feel the impact of the storm as early as late Sunday night. Its meteorological service is anticipating storm-force winds, 3 to 6 inches of rain, “hazardous” marine conditions and severe thunderstorms that may interrupt power utilities.
“All the regular preparations that we do for a hurricane is in full swing,” Minister of Home Affairs and Information Wilfred Abrahams said in a statement. “We have less than 48 hours until we expect to see the effects of this system impacting Barbados. Please use the time very wisely.”

In Saint Vincent and the Grenadines, Prime Minister Ralph Gonsalves warns that the storm could hit the islands by Monday morning as a Category 2 hurricane. The meteorological service forecasts sustained winds of 74 to 110 mph or greater and rainfall of 4 to 6 inches.
“Kingstown is going to be flooded once this hurricane is on track,” Gonsalves said of the capital city. “Normally, two inches of rain – sustained rain – in a relatively short period of time will flood the city. Four inches will undoubtedly flood the city.”
In Saint Lucia, the government warns that the storm could bring “moderate to heavy showers, thunderstorms, and gusty winds” to the region. Prime Minister Philip J. Pierre is advising residents to make necessary preparations and review their family emergency plans.
In Grenada, the National Disaster Management Agency is also urging residents to prepare by having disaster supplies kits, trimming overhanging trees and branches, clearing drains and knowing where their emergency shelters are located.

NOAA predicts above-normal hurricane season
Systems forming this early in the summer in this part of the Atlanticis a sign of the hyperactive hurricane season to come, according toresearch fromPhil Klotzbach, a hurricane expert and research scientist at Colorado State University.Normally, ocean temperatures aren’t warm enough in June and July to help tropical systems thrive.
National Weather Service forecasterspredict 17 to 25 named storms this season, with eight to 13 of those becoming hurricanes, including four to seven major hurricanes.
“That’s well above average,” Brennan noted.
The weather service says that’s “due to a confluence of factors, including near-record warm ocean temperatures in the Atlantic Ocean, development of La Nina conditions in the Pacific, reduced Atlantic trade winds and less wind shear, all of which tend to favor tropical storm formation.”
