The readings are not a mistake. The wind speed is at the periphery as much as the "eye wall." The "eye" for Irma is on the west side of Florida while the winds are still over the hottest waters on the east side of Florida.
The "Irma system" is extensive. It has just gone through a high energy event that removed the heat transfer system to the north. The storm actually increased in diameter when it disconnected into a more autonomous system.

Kindly note the high energy content of Iram at it's most southern end. The water is hot. The "eye" will more north, but, slowly. That is the issue. The longevity of the storm is the most destructive aspect. The storm surge builds with sustained winds. The land is receiving sustained flooding and winds. Jose is a worry. It south of Irma and of course located southeast of Irma, but, Jose is traveling north west.
