Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...A strong deep level trough will continue across the
Caribbean through tonight, then lift out to the NE Thu through
Sat. This feature will support active weather across the central
portions of the basin, which will gradually shift NE and into
the Atlc through Fri. Fresh to strong E to SE winds in the
central Caribbean will shift northeastward tonight through Thu
while diminishing to mostly fresh speeds. A broad and weak
trough will prevail across the north-central Caribbean Thu night
through Sat, yielding moderate trade winds across the E portions
and moderate to fresh winds across NW portions of the basin.
Smoke due to agricultural fires in Central America continues
across the Gulf of Honduras, and spreads NW to the Yucatan
coast.
