DISCUSSION AND OUTLOOK
----------------------
At 800 AM AST (1200 UTC), the eye of Hurricane Beryl was located
near latitude 10.6 North, longitude 53.9 West. Beryl is moving
toward the west near 21 mph (33 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 early on Monday and across the
southeastern Caribbean Sea Monday night and Tuesday.

Aircraft data indicate that the maximum sustained winds have 
increased to near 115 mph (185 km/h) with higher gusts, making 
Beryl a very dangerous category 3 hurricane.  Continued rapid 
strengthening is forecast over the next day or so, and Beryl is 
expected to become an extremely dangerous category 4 hurricane 
before it reaches the Windward Islands.

Hurricane-force winds extend outward up to 15 miles (30 km) from
the center and tropical-storm-force winds extend outward up to 80
miles (130 km).

The minimum central pressure based on data from the Air Force 
Hurricane Hunters is 968 mb (28.58 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 on Monday.  Devastating wind damage is expected
where the eyewall of Beryl moves through portions of the Windward
Islands.

Tropical storm conditions are expected in the tropical storm warning
area starting late tonight, making outside preparations difficult or
dangerous.

Tropical storm conditions are possible within the watch area
starting late tonight.

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.

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 flow near where Beryl 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 tonight
and Monday. 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.  These swells are expected to cause life-threatening surf and 
rip current conditions. Please consult products from your local 
weather office.
