OK..I am going toparaphrase some discussion from East Coast Weather Forums. Some of the People over there are saying Katrina may have just completed an eyewall replacement in the last 6 hours.

Basically what we have seen happen -- 1 PM 175 MPH winds 902 MB, Cloud tops have warmed since then, eyewall presentation became somewhat ragged (not much but it is there on the loops), Recon reported Open Eye to the SW, 7PM 160 MPH 904 MB.

Now if you watch the loops closely, the eye is becomeing symetrical again, cloud tops are cooling, and the opening is gone.

All just speculation I am passing along, but it is possible she may have just gone through an ERC. As I said earlier the next few hours will tell alot.

If the Next Vortex shows a closed eye and steady or lowering Pressure, then the theory may be correct. Let;s hope they are wrong.

Thanks for the details. Can you explain the significance of an eyewall replacement, please?
