.SYNOPSIS....Showers and thunderstorms continue in association
with a broad area of low pressure and a tropical wave over the
central Caribbean Sea. Environmental conditions appear 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 Sea. Afterward, further
development is likely while the disturbance meanders over the
western Caribbean Sea through the weekend. The system is
forecast begin moving slowly NW by early next week. Regardless
of development, heavy rains are expected over Jamaica and
portions of Haiti during the next day or so, and over the NW and
portions of the SW Caribbean through early next week.
Additionally, strong to near gale force winds are expected to
develop over the NW Caribbean Wed night and reach gale force
speed by Thu night, building rough seas across the region.
Otherwise, gentle to moderate winds and slight to moderate seas
will dominate the central and eastern Caribbean through the
forecast period.
