Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...High pressure north of basin combined with the
Colombian low will support fresh to locally strong winds and
moderate to rough seas over the waters just offshore Venezuela
and Colombia mainly at night through Sat. After a brief lull, a
passing tropical wave will cause similar wind speeds again
starting Tue. In the Gulf of Honduras, pulsing winds of fresh
speeds with moderate seas are expected Sat night through Wed
night. Elsewhere, gentle to moderate winds and slight to
moderate seas are forecast through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS....A relatively weak pressure gradient will support
gentle to moderate winds and slight to moderate seas across the
region through Sun, except for occasional fresh pulsing winds
near Hispaniola. Low pressure...AL96...is likely to approach the
eastern waters late Sun into Mon. Development of this system
into a tropical cyclone appears unlikely during the next day or
two due to surrounding dry air, but environmental conditions are
forecast to become more conducive in a few days. A tropical
depression could form during the early or middle part of next
week while the system moves northwestward to northward across the
central tropical and subtropical Atlantic. Currently, there is a
medium range of tropical cyclone formation over the next 7 days.
