DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Hurricane Beryl was located
near latitude 18.7 North, longitude 81.8 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 away from the Cayman Islands this morning and
over the Yucatan Peninsula early Friday. Beryl is expected to emerge
over the southwestern Gulf of Mexico Friday night and turn
northwestward.

Reports from a NOAA Hurricane Hunter aircraft indicate that maximum
sustained winds are near 120 mph (195 km/h) with higher gusts.
Beryl is a category 3 hurricane on the Saffir-Simpson Hurricane
Wind Scale. Weakening is forecast during the next day or two,
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 175
miles (280 km). Grand Cayman Island recently reported sustained
winds of 44 mph (70 km/h) and a wind gust of 54 mph (87 km/h).

The minimum central pressure from the Hurricane Hunter aircraft
data is 968 mb (28.59 inches).

area of the Yucatan Peninsula late today.

Tropical storm conditions are possible in the tropical storm watch
