Post-Tropical Cyclone Hilary Discussion Number 39
NWS National Hurricane Center Miami FL EP092017
800 PM PDT Sun Jul 30 2017
Hilary has been without deep convection for over 15 hours now,
and there is little chance of any convection redeveloping since
the cyclone is now over very cold waters. Thus, Hilary is no longer
a tropical cyclone, and this is the last advisory. The initial wind
speed is set to 30 kt, assuming some spin-down of the winds since
the ASCAT pass nine hours ago. The remnant low should gradually
weaken due to the cold waters and dry air mass. The remnants are
forecast to turn westward and slow down in a day or so with most
models dissipating the circulation in a couple of days.
