DISCUSSION AND OUTLOOK
----------------------
At 500 AM AST (0900 UTC), the eye of Hurricane Beryl was located
near latitude 11.7 North, longitude 59.9 West. Beryl is moving
toward the west near 20 mph (31 km/h). A continued quick westward to
west-northwestward motion is expected during the next few days. On
the forecast track, the center of Beryl is expected to move across
the Windward Islands this morning and across the southeastern and
central Caribbean Sea late today through Wednesday.
Maximum sustained winds remain near 120 mph (195 km/h) with higher
gusts. Beryl is a category 3 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 core moves through the Windward
Islands into 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 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 125 miles
(205 km). Grantley Adams International Airport on Barbados
recently reported sustained winds of 45 mph (72 km/h) with a gust
to 60 mph (96 km/h).
The estimated minimum central pressure is 965 mb (28.50 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 expected in the hurricane warning
area beginning early this morning. Potentially catastrophic wind
damage is expected where the core of Beryl moves through portions of
the Windward Islands, with the highest risk of the core in St.
Vincent and the Grenadines, and Grenada.
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.
Tropical storm conditions are expected in the tropical storm warning
area starting soon, making outside preparations difficult or
dangerous.
Tropical storm conditions are possible within the watch area
starting this morning for Dominica, and 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 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 are expected across 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 in the next day or so. These swells are expected to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
