Tropical Depression Ten-E Discussion Number 7
NWS National Hurricane Center Miami FL EP102020
200 PM PDT Fri Aug 14 2020
ASCAT-B data valid around 1900 UTC showed max winds a little higher
than 30 kt associated with the rain-free circulation of the
depression. However, since that time, the convective structure of
the cyclone has degraded substantially and if it was previously
producing winds of tropical-storm-force, it likely no longer is
doing so at this time. Therefore, the initial intensity for this
advisory is held at 30 kt.
Only minor fluctuations in the intensity and structure of the
depression are expected for the next 3 days due to strong
northeasterly wind shear. Assuming the system doesn't dissipate at
some point during that period of time, the upper-level winds could
become less hostile early next week. The dynamical guidance
generally indicates that the tropical cyclone will hang on and
modest strengthening is possible early next week. No changes
were made to the NHC intensity forecast, which closely follows the
multi-model consensus.
Likewise, only minor adjustments were made to the NHC track
forecast. The depression is still forecast to meander for the next 5
days, initially west-southwestward to westward, then northwestward
over the weekend. The strength of a low- to mid-level ridge to the
north of the cyclone is the primary factor in the steering flow.
While there are slight variations from model to model on the speed
and heading of the tropical cyclone, they all agree that it won't
move much through the early portion of next week, and possibly even
beyond that. The NHC forecast essentially splits the difference
between the previous official forecast, HCCA, and TVCE.
