DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Beryl was located
just offshore of the southwest part of Jamaica near latitude 17.8
North, longitude 78.3 West. Beryl is moving toward the
west-northwest near 20 mph (31 km/h). A westward to
west-northwestward motion is expected during the next day or
two, taking the core of Beryl just south of Cayman Islands tonight
and over the Yucatan Peninsula late Thursday night and Friday.
Beryl is expected to emerge over the southwestern Gulf of Mexico
Friday night and turn northwestward.

Maximum sustained winds are near 130 mph (215 km/h) with higher
gusts.  Beryl is a category 4 hurricane on the Saffir-Simpson
Hurricane Wind Scale.  Some weakening is forecast during the next
day or two.  However, Beryl is forecast to be at or near major
hurricane intensity while it passes the Cayman Islands.  Additional
weakening is expected thereafter, though Beryl is forecast to remain
a hurricane until it makes landfall on the Yucatan Peninsula.

Hurricane-force winds extend outward up to 45 miles (75 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km).

The minimum central pressure based on data from the Air Force and
NOAA Hurricane Hunters is 960 mb (28.35 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 continue across southwestern portions of
Jamaica and in the mountainous areas.  Tropical storm conditions
are occurring elsewhere on the island.

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 expected to reach the Cayman Islands
late tonight, with tropical storm conditions expected to begin
within the next couple of hours.

Hurricane conditions are expected in the hurricane warning area on
the Yucatan Peninsula Thursday night or early Friday morning.  Winds
are expected to first reach tropical storm strength by late
Thursday, making outside preparations difficult or dangerous.

Hurricane conditions are possible in the hurricane watch area
along the east coast of the Yucatan Peninsula as early as late
Thursday.

Tropical storm conditions are expected in the tropical storm warning
area in the tropical storm warning area of the Yucatan Peninsula by
late Thursday.

Tropical storm conditions are possible in the tropical storm
watch area along portions of the coast of Belize by late Thursday
or early Friday, and in the tropical storm watch area along the
coast of the Yucatan Peninsula by Friday.

STORM SURGE:  Storm surge could raise water levels by as much as 6
to 9 feet above normal tide levels in areas of onshore winds along
the immediate coast of Jamaica.

Storm surge could raise water levels by as much as 2 to 4 feet above
normal tide levels in areas of onshore winds along the immediate
coast of the Cayman Islands.

Storm surge could raise water levels by as much as 4 to 6 feet
above ground level in areas of onshore winds along the east coast of
the Yucatan Peninsula within the hurricane warning area.

Near the coast, the surge will be accompanied by large and
destructive waves.

RAINFALL:  Beryl is expected to produce rainfall totals of 4 to 8
inches with localized amounts of 12 inches across Jamaica through
Wednesday evening, along with additional rainfall of 4 to 6 inches
over the Tiburon Peninsula of Haiti. This heavy rainfall is expected
to cause life-threatening flash flooding and mudslides.

Beryl is also expected to bring rainfall totals of 4 to 6 inches
over the Cayman Islands Wednesday night into Thursday. Over the
Yucatan Peninsula into northern Belize, Beryl is expected to produce
rainfall totals of 4 to 6 inches with localized amounts of 8 inches
late Thursday through Friday. Scattered instances of flash flooding
are anticipated.

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 currently impacting
portions of the coast of Jamaica, Cuba, and the Cayman Islands.
These swells are expected to spread to the Yucatan Peninsula and
portions of Central America on Thursday and to eastern Mexico and
much of the Gulf Coast of the U.S. by late Friday. These swells are
expected to cause life-threatening surf and rip current conditions.
