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.
