...TROPICAL WAVES...
Three tropical waves are noted between the W coast of Africa and
the Lesser Antilles.
A tropical wave axis extends from 02N24W to 12N23W. This system
is moving W around 10 kt and is well defined in the TPW product as
well as in model diagnostic guidance. Associated convection has
greatly diminished during the past several hours with only
scattered showers leftover.
A tropical wave over the central Atlantic has an axis extending
from 02N43W to 12N40W, moving W at 5 to 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 tropical N Atlantic has an axis
extending from the coast of Suriname near 04N56W to 14N53W,
moving W around 15 kt. The wave coincides with a high amplitude
bulge of moisture as depicted in the TPW product. Currently,
scattered moderate convection is seen from 08N to 10N between 53W
and 56W.
A tropical wave moving westward over the central Caribbean has an
axis extending from the Guajira Peninsula in NE Colombia near
12N73W to the S coast of the Dominican Republic near 18N71W,
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 Gulf of Tehuantepec in the
Tropical NE Pacific extends northward through the Chivela Pass
into the Bay of Campeche near 20N95W and is moving W around 15 kt.
TPW satellite imagery indicates this wave is embedded in deep
layer moisture. The wave is also interacting with an upper-level
trough over the Gulf of Mexico. Scattered moderate convection is
occurring S of 20N E of the wave axis to 93W.
