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

.SYNOPSIS...High pressure over the central Atlantic will support
strong to near gale east to southeast winds near the Gulf of
Honduras, moderate to fresh winds in the south-central and in
the southeastern Caribbean, with gentle to moderate winds
elsewhere into the upcoming week. The pressure gradient will
tighten early next week, with fresh to strong trade winds
expected in the south- central and in the northwestern
Caribbean, and moderate to fresh trade winds elsewhere. Seas
will build next week as a result of the increasing winds.
Meanwhile, haze due to agricultural fires in Central America
continues across some areas of the northwestern Caribbean.
