Synopsis for Caribbean Sea, and Tropical N Atlantic from 07N to
19N W of 55W
401 PM EDT Thu Apr 16 2026
.SYNOPSIS...A surface trough extending from Hispaniola northward
into the western Atlantic will move slowly westward and weaken
through Sat. This feature will disrupt the typical pressure
pattern across the basin during this time. Expect fresh trade
winds and moderate seas off the coast of Colombia overnight, then
mainly gentle to moderate winds are expected there during the
remainder of the week. Winds and seas will generally diminish
across the basin as the trough passes north of the area Fri
through the weekend. Looking ahead, expect fresh NE winds early
next week across the Windward Passage associated with a late-
season cold front moving into Cuba.
