Well that's not good for MS Gulf Coast. That's less than 10mi W of where Camille hit, and she was a much smaller storm. Even with just due N movement and no eastward component at all that puts the (remainder of?) the eastern eyewall right around Long Beach or Gulfport, and the remaining strongest winds from there to the MS/AL border.

However there is likely to be some eastward component to the movement, and in addition, migration of the eastern eyewall to the east as the eye expands and possibly even falls apart. So that moves the eastern eyewall even further east on the MS coastline.

Regarding my earlier post, it does appear that the remaining stronger bands on the east side of the storm are taking a big hit as soon as even the leading part of the band approaches land. In fact there even seems to be a kind of shock wave propagating effect down the band, reducing the water vapor along the entire length of the band that is still in the gulf, when even just one edge of the band comes in contact with land (0645Z to 0715Z wv sat images on floater).
