from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.

height of the highest 1/3 of the waves. Individual waves may be
more than twice the significant wave height.

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

.SYNOPSIS...Weak high pressure ridge prevails just N of the
area, to the E of 74W. The pressure gradient between the ridge
and lower pressure over northern South America is supporting
fresh to strong E winds in the south-central Caribbean. 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 very active weather across the central portions of
the basin today, and will gradually shift NE through Fri. Fresh
to strong E to SE winds will develop in the central Caribbean
this afternoon, ahead of the active weather, and shift
northeastward through Thu while diminishing to mostly fresh
speeds. Smoke due to agricultural fires in Central America
continues across the Gulf of Honduras, but continue to thin out.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A weak stationary front extends across the northern
waters, from 31N64W to 1011 mb low pressure near 28N76W then
continues as a trough across the Florida Straits. Scattered
showers and thunderstorms prevail across the western Atlantic
between the front and 64W, supported by a deep layered upper
trough. The front will weaken by Wed morning. A trough will
develop just southeast of the weakening front and extend into the
central Bahamas on Wed, then drift eastward through Thu night.
Moderate winds and seas will prevail in the western Atlantic with
the front and trough through midweek. Weak low pressure is
expected to develop just N of Hispaniola Thu night and shift N-NE
through Sat, accompanied by moderate to fresh winds and active
weather.
