...TROPICAL WAVES... 

Three tropical waves are noted between the W coast of Africa and
the Lesser Antilles.

A tropical wave is added to the 1200 UTC analysis/surface map
along 18W/19W based on the Hovmoller Diagram that shows the
westward propagation of the wave. This system is also well 
defined on the TPW product, and model diagnostics guidance. 
Scattered moderate to isolated strong convection is near the
southern end of the wave's axis from 5N-9N between 16W-19W.

A tropical wave is in the E Atlantic, with axis extending from 
13N33W to 04N34W, moving W at 10 kt. A modest surge of moistened
air is noted in association with the wave in TPW imagery. 
Scattered showers are where the wave meets the ITCZ axis.

A tropical wave is in the central Atlantic, with axis extending 
from 15N47W to 04N48W, moving W at 10 kt. The wave coincides with
a high amplitude bulge of moisture as depicted in the TPW product.
Currently, shallow moisture and isolated showers are observed 
near the wave's axis. This wave will move across the waters E of
the Lesser Antilles Sun night through Mon night, and the eastern 
Caribbean Tue through Wed night.

A tropical wave is moving westward across the eastern Caribbean.
Its axis extends along 66W/67W. African dust surrounds the wave. 
As a result, shallow moisture with embedded showers is associated 
with the wave. This wave will move across the remainder of the 
eastern Caribbean through Sun, the central Caribbean Sun night 
through Tue and the western Caribbean Tue night through Wed night.

A tropical wave is moving across Central America, with axis along
87W/88W from 11N-20N, moving W at 10 kt. Scattered moderate to 
isolated strong convection is near the southern end of the wave's 
axis affecting parts of Nicaragua, Honduras, and El Salvador. The 
GFS model indicates plenty of moisture over Central America and
the Yucatan Peninsula this weekend.
