Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A Gale Warning is in effect beginning on Thu for the
SW Caribbean related to Invest AL99. A tropical wave/broad area
of low pressure, AL99, over the west-central Caribbean continues
to produce a large area of showers and thunderstorms between 74W
and 84W. Environmental conditions are conducive for development,
and a tropical depression is likely to form within the next
couple of days while the system moves slowly westward into the
western Caribbean. Afterward, further development is likely
while the disturbance meanders over the western Caribbean
through the weekend. The system is expected to turn slowly
northwestward by early next week. Regardless of development,
heavy rains are expected over Jamaica during the next day or so.
Elsewhere, gentle to moderate winds and slight to moderate seas
will prevail through the forecast period.
