DISCUSSION AND OUTLOOK ---------------------- At 900 AM GMT (0900 UTC), the center of Post-Tropical Cyclone Fernand was located near latitude 41.2 North, longitude 42.9 West. The post-tropical cyclone is moving toward the east-northeast near 23 mph (37 km/h) and this motion with some additional increase in forward speed is forecast until the system opens up into a trough. Maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. The post-tropical cyclone is expected to open up into a trough in 24-36 hours. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.

Expires:No;;471237 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.
