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

.SYNOPSIS...A deep layer trough will dig southward across the
western Caribbean through Wed, then lift out to the NE through
Fri. This feature will support active weather across the central
portions of the basin, which will gradually shift NE through
Fri. Fresh to strong E to SE winds in the central Caribbean
through Wed will shift northeastward Wed night through Thu while
diminishing to mostly fresh speeds. A broad and weak trough will
prevail across the central Caribbean Fri and Sat, yielding
moderate trade winds across the E and 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.
