Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...Ridging north of the area over the western Atlantic
is shifting southeastward today ahead of a cold front moving off
the east coast of Florida. This pattern will support fresh to
strong trade winds over the southern Caribbean, but gentle to
moderate winds elsewhere through Thu. The cold front will move
into the northwest Caribbean late Thu, stall briefly Fri from
central Cuba to the northeast Yucatan Peninsula, then lift north
Sat. Meanwhile, a trough will move westward through the Windward
Islands Thu, and into the central Caribbean by Sat. Looking
ahead, another front may move into the northwest Gulf Sat night
and Sun, stall from the Windward Passage to Belize by Sun night,
then dissipate Mon.
