Re: ATL: Hurricane IGOR - Discussion
Definitely see the eye contraction. Typical of intensification or EWRC - but in this case I won't weigh in on which!

I have little concern. As wxman mentions it will start to move more west northwest. Models are not going to be wrong. There is clearly a weakness.

1200 CMC disagrees. It shows Igor missing the weakness and continuing west towards the Bahamas. Personally, I see the recurve scenario playing out, but the models are not unanimous:

Keep leaning on the models.. what happens when its at 60 W and still trucking west

Re: ATL: Hurricane IGOR - Discussion
I do love the model runs. Its like those doomsday scenario's on discovery. That being said, it is way to early to say a recurve is a given. Earl had much more support based on evolving synoptics. This one is way to soon to call.

Igor is a little south of the points but well within the wobble factor

I'll be leaning on the models if they become unanimous.

Oh, for sure. GFDL is so bull-ish right now, every run on every invest evolves into a Cat3+.

Giving this a zero chance of reaching the U.S. when there are models that disagree, when there is a possibility of it missing the weakness, is way too low. I agree that the chance is very low but it's certainly not 0%.

While I fully expect Igor to undergo an ERC at some point, right now I just don't see it starting to happen. The core looks extremely intense and very stable with no indication I've seen of a secondary eyewall even starting to form.
What you are missing and what everyone else is saying is that a new convective band DID develop around the eye this evening (the ring of red around the original eye.) That is step 1 in the process of ERC. Step 2 is that the original eyewall starts contracting. That appears to be occurring. So step 1 happened and step 2 is occurring...

Yea, I don't think Igor has even a remote chance to affect the US. It's not as if there's a solid high pressure ridge parked north of it extending out to the east coast.....I guess the only question is where and when exactly it will make the turn, as opposed to IF.

Wow! Gusts to 160. Good call keeping it at a strong 4. Likely the peak for now but the 5 am should be interesting!
