Post-Tropical Cyclone Newton Discussion Number 17
NWS National Hurricane Center Miami FL EP152022
200 PM PDT Sun Sep 25 2022

Satellite images during the last 24 hours indicate that Newton has not produced much convection, and a brief burst overnight was too ephemeral to qualify as organized enough for a tropical cyclone. Thus, this system has degenerated to a remnant low, and this is the last NHC advisory. The initial wind speed is set to 25 kt, assuming some spin down of the vortex since this morning. The remnant low should continue moving southwestward for the few days before opening up into a trough. At the same time, the system should gradually weaken. This solution is consistent with the previous forecast and the consensus aids.

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
