000 WTPZ45 KNHC 091438 TCDEP5 Post-Tropical Cyclone Octave Discussion Number 38 NWS National Hurricane Center Miami FL EP152025 800 AM MST Thu Oct 09 2025 Octave's low-level center has become exposed due to increasing wind shear. The small area of convection that the system had produced overnight has collapsed. Given the wind shear, Octave is not forecast to regain convection and thus is designated as a remnant low with an initial intensity of 30 kt. The center of Octave has already become a little more ragged on satellite imagery and the system is expected to open up into a trough and dissipate later today. This is the last public advisory issued by the National Hurricane Center on this system. For additional information on the remnant low please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php FORECAST POSITIONS AND MAX WINDS INIT 09/1500Z 17.7N 110.5W 30 KT 35 MPH...POST-TROPICAL 12H 10/0000Z...DISSIPATED $$ Forecaster Kelly
