...TROPICAL WAVES...

Currently, two tropical waves are observed between the coast of 
Africa and the Lesser Antilles. Two tropical waves are moving 
across the Caribbean Sea. 

A tropical wave is along 21W from 4N-13N moving westward 15 to 20
kt. The Hovmoller Diagram indicates the westward propagation of 
the wave, and model diagnostics guidance also suggests the presence
of this system. This wave shows up well as a low amplitude moisture
surge on the TPW product. Currently, convection is limited along 
the wave's axis due to the presence of African dust.

A second tropical wave extends its axis along 35W/36W south of 
15N, moving westward 10 to 15 kt. Isolated moderate convection is
seen where the waves axis meets the ITCZ. Saharan dust surrounds 
the wave.

A tropical wave has entered the Caribbean Sea. Its axis is along 
62W south of 18N, moving westward 15 to 20 kt. A patch of low
level moisture with embedded showers is associated with the wave,
affecting parts of the Lesser Antilles. The wave will pass south
of Puerto Rico tonight, and reach Hispaniola on Sun.

A tropical wave is moving across the western Caribbean Sea around
10 kt. Its axis is along 86W, south of 18N. The wave will pass 
west through the Gulf of Honduras through this evening and interact
with an upper-level trough resulting in continued thunderstorm 
development across parts of the western Caribbean and northern 
Central America.
