Hurricane Beryl Discussion Number  12
NWS National Hurricane Center Miami FL       AL022024
1100 AM AST Mon Jul 01 2024

Satellite and radar data this morning suggest Beryl has completed an 
eyewall replacement cycle. Radar images from Barbados show a solid 
ring of deep convection surrounding the warming, well-defined eye of 
the hurricane. Data collected by the NOAA and Air Force Hurricane 
Hunters this morning confirm that Beryl has strengthened. Dropsondes 
indicate the central pressure has fallen to around 956 mb, and the 
earlier flight-level winds and SFMR data supported an intensity of 
around 115 kt a couple of hours ago. The hurricane's satellite 
structure has continued to improve this morning, and recent 
objective satellite estimates justify raising the initial intensity 
to 120 kt. The core of the powerful hurricane is nearing Carriacou 
Island, Grenada, and the Grenadine Islands, where conditions are 
rapidly deteriorating and residents should take action to protect 
their lives.

Aircraft and radar fixes indicate Beryl has jogged northwestward 
over the past several hours, and the initial estimated motion is 
west-northwest or 285/17 kt. The hurricane is currently moving 
across the southern Windward Islands. A mid-level steering ridge to 
the north of Beryl should steer the hurricane quickly 
west-northwestward to westward across the Caribbean Sea during the 
next few days as a mid-level ridge strengthens to the north of the 
cyclone. This portion of the track forecast is very similar to the 
previous advisory, and the NHC forecast remains close to the 
multi-model consensus aids. At days 3-5, there is some increased 
spread in the track guidance, likely regarding the strength of the 
steering ridge as Beryl approaches the northwestern Caribbean Sea 
and the Yucatan Peninsula. This portion of the forecast was nudged 
slightly north of the previous one, but still lies south of the 
consensus aids.

Since the eyewall replacement cycle has completed, the updated NHC 
forecast allows for some additional near-term strengthening based on 
recent aircraft data and the improved satellite and radar structure 
of the hurricane. As previously noted, an increase in westerly shear 
is expected by midweek, which is expected to induce some weakening 
while Beryl moves across the central and northwestern Caribbean Sea. 
This is reflected in the latest NHC prediction that follows the 
multi-model consensus trends. Regardless, Beryl is forecast to 
remain a powerful hurricane through late this week, and interests in 
the northwestern Caribbean and the Yucatan Peninsula should continue 
to monitor the latest forecast updates. 

Based on the latest NHC forecast, the government of Jamaica has 
issued a Hurricane Watch for the island.

Key Messages:

1. The eyewall of Beryl is moving through the southern Windward 
Islands. This is an extremely dangerous and life-threatening 
situation. Take action now to protect your life! Residents in
Grenada, the Grenadine Islands, and Carriacou Island should not 
leave their shelter as destructive winds and life-threatening storm 
surge are expected during the next few hours. Shelter in place 
through the passage of these life-threatening conditions and do not 
venture out in the eye of the storm.

2. Heavy rainfall and localized flash flooding are expected across 
the Windward Islands through this afternoon.

3. Beryl is expected to remain a powerful hurricane as it moves 
across the Caribbean Sea later this week. A Hurricane Watch has been 
issued for Jamaica. Interests in the Cayman Islands, Belize, the 
Yucatan Peninsula, and the remainder of the northwestern Caribbean 
should monitor its progress. Additional watches and warnings will 
likely be required during the next day or two.
