through Saturday night, followed by a turn toward the northwest and

north-northwest on Sunday and Monday. On the forecast track, the

center of the cyclone is forecast to move across the central

Caribbean Sea through Saturday, pass south of Jamaica on Saturday

night and Sunday, and approach the Cayman Islands on Sunday night

and early Monday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.

Some slow strengthening is forecast during the next day or so, and

the depression is expected to become a tropical storm by tonight.

More significant intensification is forecast on Sunday and Monday,

and the system is forecast to become a hurricane by early Monday.

The estimated minimum central pressure is 1006 mb (29.71 inches).
