DISCUSSION AND OUTLOOK
At 500 AM AST (0900 UTC), the center of Hurricane Beryl was located
near latitude 11.1 North, longitude 49.8 West. Beryl is moving
toward the west-northwest near 14 mph (22 km/h). A west-
northwestward motion with some increase in forward speed is expected
during the next few days. On the forecast track, the center of
Beryl will approach the Lesser Antilles over the weekend and cross
the island chain late Sunday or Monday.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Due to the small size of the hurricane, short-term changes
in intensity, up or down, could occur over the next day or two, but
Beryl is forecast to be near hurricane strength as it nears the
Lesser Antilles. Weakening is expected once Beryl reaches the
eastern Caribbean Sea on Monday, but the system may not degenerate
into an open trough until it reaches the vicinity of Hispaniola and
the central Caribbean Sea on Tuesday or Wednesday.
Beryl is a small hurricane. Hurricane-force winds extend outward up
to 10 miles (20 km) from the center and tropical-storm-force winds
extend outward up to 35 miles (55 km).
The estimated minimum central pressure is 995 mb (29.39 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm or hurricane conditions are possible within
the watch areas by late Sunday or Monday.
RAINFALL: Beryl is expected to produce total rain accumulations
of 2 to 4 inches through Sunday across the southern Leeward Islands
and northern Windward Islands, including Guadeloupe, Dominica,
Martinique, St. Lucia, and Barbados. Elsewhere across the northern
Leeward and southern Windward Islands, rainfall amounts of 2 inches
or less are expected.
