Dangerous Hurricane Beryl moved closer to Jamaica on Tuesday evening. At 11:00 p.m. EDT on Tuesday the center of Hurricane Beryl was located at latitude 16.2°N and longitude 72.7°W which put the center about 300 miles (400 km) east-southeast of Kingston, Jamaica. Beryl was moving toward the west-northwest at 22 m.p.h. (35 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 175 m.p.h. (280 km/h). The minimum surface pressure was 947 mb.
Hurricane Warnings were in effect for Jamaica, Grand Cayman, Little Cayman and Cayman Brac.
A Hurricane Watch was in effect for the South coast of Haiti from Anse d’Hainault to the border with the Dominican Republic. A Hurricane Watch was also in effect for portion of the coast from Cabo Catoche to Chetumal, Mexico.
A Tropical Storm Warning was in effect for the south coast of the Dominican Republic from Punta Palenque to the border with Haiti. A Tropical Storm Warning was also in effect for the south coast of Haiti from Anse d’Hainault to the border with the Dominican Republic.
A Tropical Storm Watch was in effect for the portion of the coast from Chetumal, Mexico to Belize City, Belize.
U.S. Air Force Reserve and NOAA aircraft continued to fly reconnaissance into Hurricane Beryl on Tuesday evening. A circular eye with a diameter of 23 miles (37 km) was present at the center of Beryl’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Beryl. Storms near the core generated strong upper level divergence that pumped mass away from the hurricane. The removal of large amounts of mass was nearly equal to the inflow of mass in the lower levels of the atmosphere. The equilibrium between upper level divergence and lower level convergence caused the surface pressure to remain nearly steady.
The size of the circulation around Hurricane Beryl increased on Tuesday. Winds to hurricane force extended out 40 miles (65 km) from the center of Beryl’s circulation. Winds to tropical storm force extended out 185 miles (295 km) from the center of Hurricane Beryl.
The Hurricane Intensity Index (HII) for Hurricane Beryl was 31.6. The Hurricane Size Index (HSI) was 13.6 and the Hurricane Wind Intensity Size Index (HWISI) was 45.2. Hurricane Beryl was similar in size and intensity to Hurricane Ida when Ida hit Louisiana in 2021.
Hurricane Beryl will move through an environment that will be less favorable for a powerful hurricane during the next 24 hours. Beryl will move over water where the Sea Surface Temperatures are near 29°C. It will move closer to an upper level low over Northwestern Caribbean Sea. The upper level low will produce southwesterly winds that will blow toward the top of Beryl’s circulation. Those winds will cause the vertical wind shear to increase. Hurricane Beryl will weaken when the wind shear increases.
Hurricane Beryl will move around the southern side of a high pressure system over the western Atlantic Ocean. The high pressure system will steer Beryl toward the west-northwest during the next 24 hours. On its anticipated track, Hurricane Beryl will begin to affect Jamaica by Wednesday morning.
Hurricane Beryl is likely to be a major hurricane when it reaches Jamaica. Beryl will be capable of causing regional major damage. Widespread electricity outages are likely. Hurricane Beryl will also drop heavy rain on Jamaica. Heavy rain is likely to cause flash floods. Beryl could cause a storm surge of up to 13 feet (4 meters) where the wind blows the water toward the coast.
The circulation around the northern side of Hurricane Beryl will cause the water level to rise along the south coasts of the Dominican Republic and Haiti. There are already reports of a storm surge along the south coast of Dominican Republic.
Hurricane Beryl will reach the Cayman Islands on Wednesday night. Beryl is forecast still to be a hurricane when it reaches the Cayman Islands.
