500 AM AST Wed Aug 12 2020
After an earlier burst of deep convection near the center and in
the western semicircle of the circulation, overall thunderstorm
activity has decreased somewhat. This is likely due to the
entrainment of mid-/upper-level dry air as noted in GOES-16
high-resolution mid- and upper-level water vapor imagery, in
conjunction with some modest southeasterly vertical wind shear.
The latest subjective and objective Dvorak satellite
classifications from TAFB/SAB and UW-CIMSS ADT of 30 kt and 33 kt,
respectively, support maintaining an initial intensity of 30 kt.
The depression continues moving a little...

1100 PM AST Tue Aug 11 2020
After weakening in the early evening hours, deep convection has
returned to the western semicircle of the tropical cyclone. While
this is quite a strong burst, it appears that the convective
pattern is indicative of the shear it is encountering, rather than
any strengthening. This is confirmed by ASCAT-B data from a few
hours ago, which supported maintaining an initial wind speed of 30
kt.
By this time tomorrow, the depression is forecast to become a
tropical storm due to decreasing vertical wind shear, and this
environmental change should also keep some of the surrounding
mid-level d...

Visible satellite imagery and ASCAT-C data from earlier in the day
have shown that the area of low pressure NHC has been monitoring
over the tropical Atlantic has developed a less-elongated
circulation with a well-defined center. For the most part, deep
convection has persisted with the system since about this time
yesterday, save a brief period of warming cloud tops this morning.
The low now meets the criteria of a tropical cyclone, and
advisories have been initiated on Tropical Depression Eleven with
30-kt winds, in line with the latest Dvorak Current Intensity
numbers from TAFB and SAB.
