Hurricane Isaias as a NOAA wave buoy in the Gulf of Mexico felt it. Buoy 42039 lies about 115 nautical miles south-southeast of Pensacola. As Isaias moved north towards the Florida Panhandle on 9 October 2026, its centre passed to the west of the buoy. The waves grew from about 2.5 metres in the early hours to a significant wave height of 8.7 metres (28 ft) at 14:50 local time, with a dominant period of 13 seconds. The wind veered from east to south-southwest and peaked at 22 m/s (43 knots), with gusts of 28 m/s, while the pressure fell to 996 hPa. Isaias came ashore near Destin that evening.
