...TROPICAL WAVES...
A tropical wave is emerging off the west coast of Africa and will
likely be added to the 1800 UTC surface map. The Hovmoller Diagram
indicates the westward propagation of the wave. A large cluster
of moderate to isolated strong convection is noted from 6N-10N
between 11W-15W in association with this system.
The axis of a tropical wave extends from 16N32W to 04N34W. African
dust surrounds the wave limiting convection. A patch of low level
moisture is near the northern end of the wave's axis.
A tropical wave is along 50W from 6N-18N, moving W at 20 kt. A
cluster of moderate to isolated strong convection is seen near the
southern end of the wave's axis from 06N-08N between 50W and 52W.
This wave will pass west of 55W early on Sat, and move across the
Windward Islands by Sat night.
The axis of a tropical wave extends from 18N65W to the coast of
Venezuela near 10N66W, moving W at 10-15 knots. The wave is
generating scattered moderate convection across the basin, mainly
E of 67W, including the Lesser Antilles, where showers and
locally heavy rain have been reported. Upper diffluent ahead of an
upper-level trough that now crosses Hispaniola is helping to
induce this convective activity. Moisture related to this wave
will spread out over Puerto Rico and the UK/US Virgin Islands
today, reaching Dominican Republic tonight into Sat, increasing
the likelihood of showers with embedded tstms. A recent scatterometer
pass clearly indicates the wind shift associated with the wave's
axis.
A tropical wave extends from the westernmost tip of Jamaica to
eastern Panama near 09N79W. Lingering moisture from this tropical
wave will continue to support scattered showers and isolated
thunderstorms across Jamaica and regional waters today. Scattered
showers and isolated tstms are observed between Haiti and
Jamaica while some shower activity is near the wave's axis from
15N-18N. Abundant tropical moisture will persist over the NW
Caribbean and central America through at least early Sat.
