Post-Tropical Cyclone Fernand Forecast Discussion Number 19
2025-08-28 10:38:26| National Hurricane Center (Atlantic)
Issued at 900 AM GMT Thu Aug 28 2025 000 WTNT41 KNHC 280838 TCDAT1 Post-Tropical Cyclone Fernand Discussion Number 19 NWS National Hurricane Center Miami FL AL062025 900 AM GMT Thu Aug 28 2025 It has now been more than 12 hours since Fernand has produced what could be considered organized deep convection near its center, and now that the cyclone has moved north of the Gulf Stream, this activity is very unlikely to come back. Therefore, Fernand is now considered a post-tropical cyclone, and this will be the final NHC advisory on the system. The maximum sustained winds have been lowered to 40 kt, assuming there has been some spin-down of the winds relative to the earlier scatterometer data, given the lack of deep convection. The system is continuing to accelerate east-northeastward, now at 060/20 kt, and this motion should continue until the post-tropical cyclone opens up into a trough in about 24-36 hours. This system will ultimately become absorbed by a larger mid-latitude cyclone forecast to develop in the far North Atlantic. Additional information on this system, including gale warnings, can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php FORECAST POSITIONS AND MAX WINDS INIT 28/0900Z 41.2N 42.9W 40 KT 45 MPH...POST-TROPICAL 12H 28/1800Z 42.7N 38.7W 35 KT 40 MPH...POST-TROPICAL 24H 29/0600Z 44.9N 31.5W 35 KT 40 MPH...POST-TROPICAL 36H 29/1800Z...DISSIPATED $$ Forecaster Papin
