DISCUSSION AND OUTLOOK
———————-
At 200 PM AST (1800 UTC), the eye of Hurricane Beryl was located
near latitude 12.8 North, longitude 62.3 West. Beryl is moving
toward the west-northwest near 20 mph (31 km/h). The center of Beryl
will move away from the southern Windward Islands tonight and pass
quickly westward to west-northwestward during the next few days. On
the forecast track, the center of Beryl will move across the
southeastern and central Caribbean Sea tonight through Wednesday.

Maximum sustained winds are near 150 mph (240 km/h) with higher
gusts. Beryl is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Fluctuations in strength are likely during the
next day or so, but Beryl is expected to remain an extremely
dangerous major hurricane as its moves over the eastern Caribbean.
Some weakening is expected in the central Caribbean by midweek,
though Beryl is forecast to remain a hurricane.

Hurricane-force winds extend outward up to 40 miles (65 km) from
the center and tropical-storm-force winds extend outward up to 125
miles (205 km). The Hewanorra International Airport on St. Lucia
recently reported sustained winds of 43 mph (69 km/h).

The minimum central pressure based on aircraft data is 946 mb
(27.94 inches).

HAZARDS AFFECTING LAND
———————-
Key messages for Beryl can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

WIND: Hurricane conditions are occurring in the hurricane warning
area. Potentially catastrophic wind damage is expected where the
core of Beryl is moving through portions of the southern Windward
Islands, including Carriacou Island, Grenada, and the Grenadine
Islands.

Wind speeds atop and on the windward sides of hills and mountains
are often up to 30 percent stronger than the near-surface winds
indicated in this advisory, and in some elevated locations could be
even greater.

Hurricane conditions are possible in the watch area on Jamaica by
Wednesday.

Tropical storm conditions are occurring in the tropical storm
warning area. Tropical storm conditions are possible within the
watch area by Tuesday afternoon for parts of the southern coast of
Hispaniola.

STORM SURGE: A life-threatening storm surge will raise water levels
by as much as 6 to 9 feet above normal tide levels in areas of
onshore winds near where the eye makes landfall in the hurricane
warning area. Near the coast, the surge will be accompanied by
large and destructive waves.

RAINFALL: Hurricane Beryl is expected to produce rainfall totals of
3 to 6 inches across Barbados and the Windward Islands through this
afternoon. Localized maxima of 10 inches are possible, especially in
the Grenadines, Tobago, and Grenada. This rainfall may cause flash
flooding in vulnerable areas.

For a complete depiction of forecast rainfall and flash flooding
associated with Hurricane Beryl, please see the National Weather
Service Storm Total Rainfall Graphic, available at
hurricanes.gov/graphics_at2.shtml?rainqpf

SURF: Large swells generated by Beryl will continue across the
Windward and southern Leeward Islands during the next couple of
days. Swells are also expected to reach the southern coasts of
Puerto Rico and Hispaniola late tonight into Tuesday. These swells
are expected to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
