Rick,
What are you looking at to say it is turning towards N.O?

Oh boy, most recent recon drops pressure to 920mb, a high15deg temp diff.
Special update just stayed with Cat 4 intensity.
Well for anyone keeping track, that is 68mb in the last 32 hours: 32mb in the first 24 hours, and 36mb in the last 8 hours, or, in other words, an average drop of 4.5mb per hour for the last 8 hours.
BTW, movement is no longer due W but now N of W, doesn't appear to be a wobble, the last few sat images...look at the high. Any extended movement to the N over the next couple hours could keep it in the loop current longer, and also move landfall significantly east.

No one has said it but just dropped from 944 to 920 in a little under 3 hours. This could go/is heading for sub 900!
Perhaps not the time for levity but do you wonder if the aliens on Jupiter are saying, "Holy crap, look at that mother of a storm on earth!"

The safest way to deal with a potential Hurricane hitting you...is to leave and just not be there at all.

If one of the Mets could comment, does it appear over the last 3 hours that the High has in fact deteriorated? It look to be taking on a more oblong shape

Not sure, but I think they are waiting for a really good fix before either sending out a special advisory package or just waiting for the 2pm package anyway. Flight-level winds are up there; I've seen obs of both 150kt and 152kt -- and as you noted, the pressure is down there with 928mb reported but with 35kt surface winds (120deg winds = NNE of the center). I'd estimate surface pressure at 925mb with surface winds likely to ramp up shortly in conjunction with the increasing flight-level winds. Height of the 700mb surface is at 2488m -- pretty low and abour 45m lower than the vortex message reported. Unfortunately, we may have yet another cat. 5 storm on our hands in the Gulf -- still not nearly as strong as , but very powerful nonetheless.
Added: typed this awhile ago before sending...920mb, probably 1-2mb lower than that given ~20-25kt at the surface, with 153kt FL. On the way to cat. 5.

Well, Margie see's too. Could this wobble or movement to the North be indicative of the High moving East or weakening sooner than forecasted.

What has been the longest track that you know of, a particular hurricane to remain at CAT 5?

To me it looks like it just bumped up a little bit to the north a couple frames ago, and that the movement is still west. I'd definitely call it a jog...

Latest SHIPS output brings the storm to 142 knots in 24 hours, then drops it down to 131 knots by 60 hours and 109 knots (68 kts in DSHIPS) by 72 hours, with landfall occurring somewhere in between. I'm not sure how relevant the model output is anymore, though... unpredictable processes like s are going to have as much effect on the intensity from here on out as the environmental conditions, though the latter will modulate how much the storm will be able to recover if it goes into a weakening phase.

Hey there's nothing saying that this can't go Cat5, do an then go back to a Cat5 right before landing...

Could it be possible that the jog is an indication that is cutting through the High and weakening it.

Can anyone on here explain to me what causes the storm to go through an EWR cycle?

The reasoning for that is not well understood.
