Hurricane Beryl remains a Cat. 4 storm as it heads west | TS Chris forms in SW Gulf

HOUSTON — Hurricane Beryl closed in on the southeastern Caribbean late Sunday after strengthening into what experts called an “extremely dangerous” Category 4 storm, and government officials pleaded with people to take shelter.

The storm was expected to make landfall in the Windward Islands on Monday morning. Hurricane warnings were in effect for Barbados, St. Lucia, Grenada, Tobago and St. Vincent and the Grenadines.

CURRENT LOCATION/PATH: With an update at 10 p.m. Sunday, Beryl was a Category 4 storm with maximum sustained winds of 130 mph, moving west at 20 mph.  (Update in Spanish). 

This is the earliest in a calendar year that there’s been a Cat. 4 storm in the Atlantic basin. The previous earliest was July 8, which happened in 2005.

“This is a very dangerous situation,” warned the U.S. National Hurricane Center in Miami, saying Beryl was “forecast to bring life-threatening winds and storm surge.”

Beryl was centered about 150 miles (240 kilometers) southeast of Barbados late Sunday. It had maximum sustained winds of 130 mph (215 kph) and was moving west at 20 mph (31 kph). It is a compact storm, with hurricane-force winds extending 30 miles (45 kilometers) from its center.

A tropical storm warning was in effect for Martinique and Trinidad. A tropical storm watch was issued for Dominica, Haiti’s entire southern coast, and from Punta Palenque in the Dominican Republic west to the border with Haiti.

Beryl was expected to pass just south of Barbados early Monday and then head into the Caribbean Sea as a major hurricane on a path toward Jamaica. It was forecast to weaken by midweek, but still remain a hurricane while heading toward Mexico.

The third tropical depression of the Atlantic hurricane season became Tropical Storm Chris in the Bay of Campeche. It’s expected to move into Mexico and bring flooding and possible landslides.

Hurricane warnings in effect for Barbados, St. Lucia, Grenada, and St. Vincent and the Grenadines.

Beryl is expected to be a major hurricane when it reaches the Windward Islands early Monday. It’s expected to bring destructive hurricane-force winds and life-threatening storm surge. Heavy rainfall and localized flooding along the Windward Islands is expected late Sunday and Monday.

Colorado State University released its forecast update for the 2024 hurricane season, maintaining that it will be a busy one. In April, they predicted that we could see 23 named storms and 11 hurricanes with five becoming major hurricanes. They blame the extremely warm tropical Atlantic and likely “La Niña” as the primary reasons.

On average, the Atlantic sees about 14 named storms each hurricane season. Of those, seven become hurricanes with three becoming major (Category 3 or above) storms.

Why such an active season? Dr. Phil Klotzbach, lead forecaster at CSU, says it’s because of two main factors — above-normal sea surface temperatures and expected La Niña conditions this summer. The warm water adds more energy to the tropics, making fuel for these storms more available. But perhaps more importantly, La Niña usually reduces vertical wind shear.

Winds blowing across a developing or mature tropical system can keep a budding system from developing and weaken stronger storms. This reduces the total storm count. But when La Niña conditions are in place, this wind shear is often reduced. That, combined with the warm ocean surface temps is why Dr. Klotzbach believes more storms than normal will form.
