Issued at 800 PM PDT Sun Jul 30 2017 000 WTPZ44 KNHC 310234 TCDEP4 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.
