Flight Level Wind: 122 knots (140.4 mph) Non-suspect: Highest SFMR Peak (10s Avg.) Sfc. Wind: 94 knots (108.2 mph) Suspect: Highest SFMR Peak (10s Avg.) Sfc. Wind: 130 knots (149.6 mph) This was in the eyewall, with heavy rain. Perhaps the NHC kept it at 150mph because they think this could be valid or perhaps because the plane just started sampling and they want a better idea before they make changes. Of course the flight level winds were lower so far.
