Post-Tropical Cyclone SONIA Forecast Discussion
000 WTPZ43 KNHC 290832 TCDEP3 Post-Tropical Cyclone Sonia Discussion Number 19 NWS National Hurricane Center Miami FL EP182025 200 AM PDT Wed Oct 29 2025 Sonia has succumbed to hostile environmental conditions, with satellite imagery showing no deep convection near the low-level center for about 15 hours. Therefore, Sonia is being a declared post-tropical cyclone. The latest subjective satellite intensity estimates from TAFB and SAB reflect this, deeming the system too weak to classify. A 0541 UTC Metop-B ASCAT pass revealed a large area of 25-kt winds, with a peak wind vector of 26 kt. Taking into account the likelihood of some undersampling, the initial intensity for the post-tropical remnant low of Sonia is set at 30 kt. Sonia will continue moving westward during the next day or so, steered by the low-level flow, while remaining embedded within a hostile environment. Regeneration of organized deep convection is not expected, and the remnant low of Sonia is forecast to dissipate by Thursday, if not sooner. For additional information on the post-tropical 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 29/0900Z 15.3N 126.1W 30 KT 35 MPH...POST-TROPICAL 12H 29/1800Z 15.2N 127.6W 25 KT 30 MPH...POST-TROP/REMNT LOW 24H 30/0600Z 14.7N 129.9W 25 KT 30 MPH...POST-TROP/REMNT LOW 36H 30/1800Z...DISSIPATED $$ Forecaster Jelsema (CPHC)
