Tropical Depression Ten Discussion Number   2
NWS National Hurricane Center Miami FL       AL102020
200 AM CVT Sat Aug 01 2020
 
The small depression maintained a large burst of convection in its 
northwest quadrant for several hours after the last advisory, though 
cloud tops have warmed steadily since around 00Z. An ASCAT-B pass 
near 2300 UTC showed max winds near 35 kt, but these winds coincided 
with the coldest cloud tops in Meteosat imagery at that time, 
indicating they may have been rain inflated. Data from ASCAT-C valid 
about 40 minutes earlier only showed peak winds closer to 30 kt, 
also near the deepest convection. The highest wind retrievals in the 
east half of the circulation, where you would often expect the 
highest winds for a system moving north or northwest, were between 
25 and 30 kt in both passes. Subjective Dvorak intensity estimates 
were 30 kt and 25 kt from TAFB and SAB, respectively, at 00Z. It is 
possible that the cyclone briefly had tropical-storm-strength winds 
at one point, but given the observed warming of cloud tops since 
00Z, the intensity is maintained at 30 kt for this advisory.
 
There is no real change to the forecast reasoning. The depression is 
moving northwestward and a turn toward the west-northwest is 
expected later today as it moves around a larger cyclonic gyre. 
Conditions do not appear to be favorable for any strengthening, and 
the dynamical models indicate that deep convection will dissipate 
later today due to cool underlying SSTs and a drier surrounding 
environment. The NHC track and intensity forecast is based on the 
TVCA and IVCN consensus aids and has not been changed significantly 
from the previous advisory.
