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

.SYNOPSIS...A weak and narrow Atlantic ridge extends westward
along 24N into the central Bahamas. The associated pressure
gradient is supporting fresh to strong SE winds in the Gulf of
Honduras and fresh to locally strong E winds in the south
central Caribbean. Strong winds in the Gulf of Honduras will
persist through Sun, reaching near gale-force Fri evening into
Sat morning and again Sat night. Fresh to strong winds will
pulse at night in the Gulf of Venezuela and offshore Colombia
through Sun night. Gentle to moderate winds are expected
elsewhere through early next week. Meanwhile, smoke due to
agricultural fires in Central America continues across areas of
the northwestern Caribbean, and is reducing the visibility in
the Gulf of Honduras.
