...TROPICAL WAVES...
A tropical wave has an axis from 01N to 20N along 27W. Scattered
moderate and isolated strong convection is observed from 04N-10N
between 25W-32W. While no surface observations were in the
vicinity of the wave, visible satellite imagery suggests that
either a distinct surface trough or broad low is present. A
distinct maximum in total precipitable water (TPW) exists along
and east of the wave's axis. Expect a fresh northeast to east to
southeast wind shift along the wave axis as it progresses westward
across the tropical Atlantic.
A tropical wave extends its axis along 50W from 01N to 19N, and
is estimated to be progressing west at 15-20 kt. No significant
convection is related to this wave at this time. The wave also has
negligible surface signature, though it is well-present in the
700 mb model diagnostics and TPW.
A tropical wave is analyzed across the central Caribbean and
South America along 78W from 02N to 19N, and is moving west about
15-20 kt. Scattered moderate and isolated strong convection exists
south of 13N within 300 nm west of the wave's axis. The wave has
negligible surface signature and cannot be easily identified in
TPW, though it is present in the 700 mb model diagnostics
A tropical wave is progressing west through Central America and
is currently analyzed with axis along 90W and extends south from
22N into the east Pacific near 09N. Scattered moderate and
isolated strong convection is occurring east of the wave axis over
portions of Central America. The wave does have some surface
circulation as well as being apparent in the TPW imagery. This
tropical wave has the potential to develop into an east Pacific
tropical cyclone later this week.

A Strong surge of moisture Meso type thunderstorm, more than likely
associated with a new tropical wave, is emerging off the coast of
Africa. This system is pushing more African Dust westward over the
Atlantic... RTW
