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 E to SE winds near the Gulf of Honduras
through most of the week. Fresh to strong winds are expected in
the south- central basin through Wed, where winds will decrease
to moderate to fresh through the later part of the week. Seas
will build through the week as a result of the increasing winds.
Gentle to moderate winds are expected elsewhere through most of
the week. Meanwhile, haze due to agricultural fires in Central
America continues across some areas of the northwestern
Caribbean.
