The dropsondes have found some high winds between the flight level of the plane and the surface. These are momentary winds in sondes, maybe half a second, but since they have increased from some of the previous recent missions, you can tell it is getting stronger again.

Individual sonde:

I haven't analysed it closely, such as if it was tossed out of the eyewall, but highest wind at 897mb level was 167mph. Surface was only 78mph. Again, half second winds perhaps.

But this gets factored in:

Average Wind Over Lowest Available 150 geopotential meters (gpm) of the sounding:
- Lowest 150m: 157 gpm - 7 gpm (515 geo. feet - 23 geo. feet)
- Wind Direction: 340 (from the NNW)
- Wind Speed: 105 knots (121 mph)

They have a reduction for that but I don't know what that would be.

But I look at it more that it is higher from previous missions. Highest from previous missions:

Mission 44: 167mph
Mission 43: 142mph
Mission 42: GI-V mission around the storm
Mission 41: 125mph
Mission 40: 127mph
Mission 39: 140mph
Mission 38: 137mph

You have to go all the way to mission 30 when it was 211mph. Just because other missions weren't as high doesn't mean the winds weren't higher, the plane might not have dropped a sonde where the highest wind were.
