...TROPICAL WAVES...
A tropical wave is in the E Atlantic, with axis extending from
13N29W to 03N30W, moving W at 10 kt. The wave shows up well as a
low amplitude moisture surge on the TPW product. The GOES-16
Geocolor RGB imagery shows the presence of the Saharan dust and
dry air N of the wave at 15N. Isolated moderate convection is
noted where the wave meets the ITCZ.
A tropical wave is in the central Atlantic, with axis extending
from 14N46W to 03N47W, moving W at 10-15 kt. The wave is well
depicted in the TPW product. Shallow moisture and isolated
showers are near the wave's axis.
A tropical wave is moving westward across the eastern Caribbean.
Its axis extends 61W/62W. African dust also surrounds the wave.
As a result, shallow moisture with embedded showers is associated
with the wave. Moisture related to this system will reach Puerto
Rico late today into tonight, and Hispaniola early on Sun,
increasing the likelihood of showers and isolated tstms.
A tropical wave is over the W Caribbean, with axis along 82W
from 10N-19N, moving W at 10-15 kt. Scattered showers and tstms
are seen over the SW Caribbean, likely a combination of the wave
and the proximity of the Monsoon Through. The wave will move
westward into Central America through Sat, helping to induce some
shower and tstm activity. The GFS model indicates plenty of
moisture over Central America this upcoming weekend.
