Wow that is a lot of spread between one model's ensemble members. There are even a few GFS like runs in there too.

Yes it is a pretty good spread. But the tightest clusters appear to be between the SC/NC border and Morehead City. Right now that looks like the are to bet on for landfall. Of course, where and what direction she goes after hitting land has a big implication on how bad things will be inland.

that is yesterday's run

Wow, good call. I don't know how to post the image of today's run, but here's a link https://www.weathernerds.org/tc_guidance/images/AL06_2018091012_ECENS_0-120h_large.png

Spread does seem a little more reasonable with today's 12z than the one I had erroneously mentioned earlier.

So last year Irma was as big and bad of a hurricane we had seen in many many years. Would the Florence threat be considered greater now? Cat 4 winds and surge over a much more populated area with exceptional rainfall and inland flooding.

Yea this is bad, and it's not like usual where we get a sheared out destabilized mess. This is something extraordinary

They said they moved it easy, but a bit west of model consensus.

Yeah, I’m going to follow their track for now.  Models shift every 6 hours and it does “me” no good to follow each and every shift. Not sure of the eye wall diameter in nm but just south of New River inlet atm.

Euro,Ukie and FV3(3 highest performing models)look pretty close now,think we're close to our track now.

Euro with a big shift east getting in line with the other two,its stiil a tick too far west while the Ukie is still a tick too far east in my opinion.

Have to say the FV3 has been really good on this storm so far.

Its sort of hard to sit here and fathom what we could be facing. Possibility of feet of rain and hurricane force gusts from Raleigh to the coast? No way that can happen right?

I didn’t see the Euro shifting way east. Especially not it’s ensembles.

One major takeaway from the 5PM discussion.

None of the guidance suggest that Florence has peaked in intensity,
and this is supported by a continuation of a low-shear environment,
and even warmer waters over the next 36 hours.  Thus, the intensity
forecast is raised from the previous one, bringing Florence close
to category 5 strength tomorrow. Near landfall, the vertical wind
shear could increase, along with the increasing likelihood of
eyewall cycles.  While the intensity forecast shows some weakening
of the maximum winds near landfall, the wind field is expected to
grow with time, which increases the storm surge and inland wind
threats.  The bottom line is that there is high confidence that
Florence will be a large and extremely dangerous hurricane,
regardless of its exact intensity.

So since this is going to be approaching at a rather odd angle for the area (more e to w than s to n) does that increase surge potential since it basically can work up a long fetch of surge?

Yep and with it slowing the east flow over the sounds will just lock in and not allow it to recede.....the river here will run backwards and then the rain runoff will try to go downstream and meet the surge tide and it will just be a mess.......until the surge runs out the rivers cant drain.

I’m very concerned. I have family in Charleston, and also sunset beach, NC. The ones in sunset beach don’t live in the barrier island, but they are maybe less than a mile from the sound. 

 

I know track is key. If it hits north of them, they are probably ok. If it hits near the nc/sc border, the ones in sunset beach are frankly screwed, and I doubt they will evacuate.
