Post-Tropical Cyclone Hilda Discussion Number 28
NWS National Hurricane Center Miami FL EP082021
800 AM PDT Fri Aug 06 2021
Hilda has been devoid of organized deep convection for at least 12
hours, and since the cyclone is moving over sub-23C sea surface
temperatures, regeneration of deep convection is unlikely.
Therefore, Hilda is designated as a 25 kt post-tropical remnant
low, and this is the last advisory from National Hurricane Center.
The low should continue to move further into a dry and stable air
mass and over even cooler waters. Consequently, weakening is
forecast and the remnant low of Hilda should open up into a trough
of low pressure over the weekend.
The initial motion is estimated to be west-northwestward, or 300/9
kt, and this general heading, within the low-level flow, is
forecast to continue until dissipation.
