Hurricane Beryl Forms: Major Caribbean Threat Ahead | Weather.com

Hurricane Beryl is rapidly strengthening in the central Atlantic Ocean and is a major hurricane threat to the Windward Islands, but then faces an uncertain future in the Caribbean Sea as we also track two other systems in a busy end of June pattern.

Current status: Beryl now has maximum sustained winds of 75 mph, making it the first hurricane of the season. Beryl is centered more than 700 miles east of the Windward Islands. It’s moving quickly westward over the open waters of the central Atlantic Ocean. Beryl has rapidly intensified since it became a tropical depression on Friday.

B​eryl is the easternmost hurricane to form in the tropical Atlantic during the month of June, beating out a 90+ year old record.

The first hurricane of the season typically forms around August 11, using an average from 1991-2020, according to the National Hurricane Center.

W​indward Islands danger: Beryl will likely continue to rapidly intensify on Sunday. The latest forecast from the National Hurricane Center shown below expects Beryl to become the season’s first Category 3 or stronger hurricane over record warm late-June water before it moves over the Windward Islands late Sunday night or Monday with flooding rain, storm surge and damaging winds.

Interests in the Windward islands, including Trinidad and Tobago, Barbados, Grenada, St. Lucia, St. Vincent and the Grenadines and Martinique should keep updated on the forecast of this storm and have their hurricane plans ready to go.

A​ hurricane warning has been issued for Barbados, where tropical storm conditions are expected to arrive in these islands as soon as Sunday afternoon and hurricane conditions are expected by late Sunday.

A​ hurricane watch has been issued for St Lucia, St. Vincent and the Grenadine Islands and Grenada. Tropical storm conditions may arrive in these islands as soon as late Sunday and hurricane conditions are possible by early Monday.

A tropical storm watch is in effect for Dominica, Martinique and Tobago.

You can find a map of the latest watches and warnings here. Additional watches and warnings are likely to be issued soon for other locations.

B​eryl’s uncertain Caribbean future: Beryl will move into the eastern Caribbean Sea Monday.

We then expect it to take a general west-northwest track in the Caribbean Sea through the Fourth of July week. In general, if Beryl remains strong it may track a tad farther north in the Caribbean Sea. If it is weaker, it will tend to track farther south. This uncertainty shows up in the model forecast track map below.

O​ne reason for this uncertainty is how much wind shear Beryl will face in the Caribbean Sea. Typically this time of year, Caribbean wind shear is strong enough to weaken or completely fizzle tropical systems approaching from the east. However, some model forecasts have hinted that wind shear may be lower than usual, which could allow Beryl to survive longer than usual.

T​he bottom line: It’s too soon to determine exactly where Beryl may go in the western half of the Caribbean Sea later next week. All interests around the Caribbean Sea should monitor the forecast of Beryl closely the next several days.

It’s also far too soon to tell if Beryl will eventually threaten any part of the U.S. Gulf Coast. Again, check back with us at weather.com for forecast updates in the coming days.

O​ne system in the far eastern Atlantic Ocean has a high chance of development over the next week. It will remain over the open ocean until nearing the Windward Islands around the middle of the upcoming week. It could follow Hurricane Beryl within a couple of days.

The other system near Mexico, Invest 94L, also has a medium chance of developing once it emerges into the Bay of Campeche or southwest Gulf of Mexico this weekend, before it glides into eastern Mexico early next week.

Heavy rain threat: Regardless of development, Invest 94L could dump locally heavy rainfall from parts of Central America to southern and eastern Mexico. Local flash flooding and landslides are possible, especially in areas of higher terrain.

Some increased swells, rip currents and coastal flooding are also possible along parts of the Mexican and Texas Gulf Coast Sunday into at least early Monday.

Tropical Atlantic development has happened in June as recently as last year. As senior meteorologist Chris Dolce discussed, tropical development east of the Lesser Antilles where Invest 95L is located in June is unusual, but has happened in recent years, including 2023.

L​ast June, tropical storms Bret, then Cindy, each developed well east of the Lesser Antilles in less than a week’s time. It was the first time on record two tropical storms formed east of the Lesser Antilles (east of the Caribbean islands) during the month.

B​onnie first became a tropical storm in late June 2022 east of Trinidad and Tobago before it traversed the rest of the southern Caribbean Sea, then later became an eastern Pacific hurricane.

At the end of June 2021, what would later become Hurricane Elsa first became a tropical storm in almost the same location as 2022’s Bonnie.

B​eryl could be an extreme outlier, though. If Beryl becomes a hurricane prior to Monday before reaching the Windward Islands, it would become only the second known hurricane to do so east of the Lesser Antilles in June.

A​ccording to WPLG TV hurricane expert Michael Lowry, only the 1933 “Trinidad & Tobago” hurricane first became a hurricane in June east of the Lesser Antilles, on June 27, 1933, according to NOAA’s best track database.

T​hree years ago, Elsa narrowly missed that mark. It first became a hurricane on July 2, 2021 near Barbados.
