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,
moderate to fresh winds in the south-central and in the
southeastern Caribbean, with gentle to moderate winds elsewhere
tonight. The pressure gradient will tighten early this week, 
with fresh to strong trade winds expected in the S-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.
