...TROPICAL WAVES...
Three tropical waves are noted between the W coast of Africa and
the Lesser Antilles.
A tropical wave axis extends from 04N21W to 13N20W. This system
is moving W around 10 kt well defined in the TPW product and in
model diagnostics guidance. Scattered moderate convection is
present within 120 nm of the wave axis between 04N and 09N.
A tropical wave over the E Atlantic has an axis extending from
03N41W to 13N39W, moving W around 10 kt. A modest surge of
moistened air is noted in association with the wave in TPW
imagery. Only limited cloudiness and isolated showers are
associated with this wave.
A tropical wave over the central Atlantic has an axis extending
from 05N54W to 14N52W, moving W around 20 kt. The wave coincides
with a high amplitude bulge of moisture as depicted in the TPW
product. Currently, scattered moderate and isolated strong
convection is seen from 08N to 11N between 52W and 54W.
A tropical wave moving westward over the eastern Caribbean has an axis
extending from 12N70W to 19N68W, moving W around 15 kt. African
dust surrounds the wave. As a result, only shallow moisture and
virtually no convection is associated with this wave.
A tropical wave moving across the border of Guatemala and Mexico
has an axis extending from 12N92W to 19N92W and is moving W
around 10 kt. TPW satellite imagery indicates this wave is
embedded in deep layer moisture. Scattered to numerous moderate
and isolated strong convection is occurring from 11N to 20N
between 90W and 95W.
