Hurricane Beryl was approaching the Windward Islands on Sunday night. At 11:00 p.m. EDT on Sunday the center of Hurricane Beryl was located at latitude 11.5°N and longitude 58.1°W which put the center about 150 miles (240 km) southeast of Barbados. Beryl was moving toward the west-northwest at 20 m.p.h. (32 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h). The minimum surface pressure was 959 mb.
Hurricane Warnings were in effect for Barbados, St. Lucia, Grenada, Tobago, and St. Vincent and the Grenadine Islands.
Tropical Storm Warnings were in effect for Martinique and Trinidad.
A Tropical Storm Watch was in effect for Dominica. A Tropical Storm Watch was in effect for the south coast of the Dominican Republic from Punta Palenque to the border with Haiti. A Tropical Storm Watch was in effect for the south coast of Haiti from Anse d’Hainault to the border with the Dominican Republic.
A circular eye with a diameter of 12 miles (19 km) was present at the center of Hurricane Beryl. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. The inner end of a rainband was wrapping around the existing eye and eyewall. Concentric eyewalls were likely forming. 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 in all directions. The removal of large amounts of mass was in equilibrium with the inflow of mass near the surface and the surface pressure was nearly steady.
The size of the circulation around Hurricane Beryl also remained nearly steady on Sunday evening. Winds to hurricane force extended out 30 miles (50 km) from the center of Beryl’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of Hurricane Beryl.
The Hurricane Intensity Index (HII) for Hurricane Beryl was 25.1. The Hurricane Size Index (HSI) was 10.5 and the Hurricane Wind Intensity Size Index (HWISI) was 35.6. Hurricane Beryl was similar in size and intensity to Hurricane Harvey when Harvey hit Texas in 2017.
Hurricane Beryl will move through an environment favorable for intensification during the next 24 hours. Beryl will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the central tropical Atlantic Ocean. The ridge will produce easterly winds that will blow toward the top of Beryl’s circulation. The winds in the lower levels of the atmosphere are also blowing from the east and there will be little vertical wind shear. Although Hurricane Beryl will move through an environment favorable for intensification, Beryl is likely to weaken during the next few hours. Concentric eyewalls will likely lead to an Eyewall Replacement Cycle. During an Eyewall Replacement Cycle the inner eyewall weakens and dissipates. Since the maximum wind speeds occur in the inner eyewall, Hurricane Beryl will weaken, at least temporarily, when that happens. Beryl could strengthen again after the Eyewall Replacement Cycle is over.
Hurricane Beryl will move around the southern side of a high pressure system over the Atlantic Ocean. The high pressure system will steer Beryl toward the west-northwest during the next 24 hours. On its anticipated track, the center of Hurricane Beryl will pass between Barbados and Tobago early on Monday. Hurricane Beryl will begin to affect St. Lucia, Grenada, and St. Vincent and the Grenadine Islands later on Monday morning.
The core of Hurricane Beryl could pass very close to St. Lucia, Grenada and St. Vincent and the Grenadine Islands. Beryl will be capable of causing regional severe damage. Hurricane Beryl will also drop heavy rain. Heavy rain is likely to cause flash floods in some locations. Hurricane Beryl could cause a storm surge of up to 13 feet (4 meters) on the parts of islands where the wind blows the water toward the shore.
Hurricane Beryl will also produce strong winds and heavy rain in Barbados, Tobago, and Martinique. Gusty winds and heavy rain could occur in Trinidad and Dominica.
Elsewhere, Tropical Storm Chris formed over the southwestern Gulf of Mexico near the coast of Mexico. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Chris was located at latitude 20.0°N and longitude 96.2°W which put the center about 105 miles (165 km) southeast of Tuxpan, Mexico. Chris was moving toward the west at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1005 mb.
A Tropical Storm Warning was in effect for the portion of the coast from Cabo Rojo to Puerto Veracruz, Mexico.
