...TROPICAL WAVES...

A tropical wave has an axis extending from 16N33W to 04N34W and 
is moving W around 10 kt. The wave coincides with a surge of 
moisture as noted in the TPW product, but African dust surrounds 
the northern side of the wave and is inhibiting convection there. 
Scattered moderate convection is seen within the moister southern 
portion of the wave from 01N to 08N between 30W and 36W.

A tropical wave extends from 19N52W to 05N53W. This feature is 
moving W around 10 kt. The low level cloud field associated with 
this wave exhibits an inverted-V signature. This wave shows up 
well in the TPW animation where a pronounced bulge of moisture is 
observed. This wave remains surrounded by Saharan dust which is 
limiting convection in the vicinity of this wave. Only a small 
cluster of moderate convection is noted E of the wave axis from 
09N to 11N between 49W and 51W. Moisture associated with this wave
will begin reaching the Windward Islands early this afternoon and
bring a modest increase in chances for showers and thunderstorms 
for this area during the next day or so.

A tropical wave has an axis extending from the eastern Cuba near 
21N76W to the coast of Colombia 08N77W, moving westward at around 
20 knots. The wave is well depicted in the moisture product. The 
monsoon trough extends E over the SW Caribbean from Costa Rica to 
northern Colombia near 10N74W. The tropical wave is interacting 
with the trough to generate numerous moderate and isolated strong 
convection from 11N to 13N between 81W and 84W. Scattered moderate
and isolated strong convection is found elsewhere within 120 nm 
of a line from 08N75W to 14N83W. Model guidance indicates that the
abundant moisture associated with this wave will spread W from 
the SW Caribbean over Nicaragua and Honduras this afternoon and 
tonight.

A mid to upper level low north of the Bahamas continues tracking

west and could begin to affect the Florida Peninsula this evening

and on the 4th of July enhancing the rain and storm chance tomorrow.

A low south of Mississippi is also tracking slowly westward.  This

low is producing heavy rains and storms over the lower half of

Louisiana. There are no signs of tropical cyclone formation...RTW
