Somewhat unexpectedly, Danielle has become less organized over the last few hours due to northwesterly wind shear tilting the storm somewhat, thus allowing dry air to move in from the west. Once the wind shear abates some, expected to happen over the next day or so, the strengthening of Danielle should resume and it still very well could become a major hurricane as it moves toward the general vicinity of Bermuda.
I attached above the water vapor image (notice the blacks/reds west of Danielle -- very dry air).
