HYCOM makes me think we may be seeing a crash this year.

But I want to see what the rest of this month brings before deciding either way.
Great post and comments, thx.
That (probable) thinning in ESS is scary indeed. BTW the same model predicts Beaufort MYI approach the coast, and get thinner. Open waters are warming up enough perhaps, plus insolation?
Perhaps.
On my mind is the distribution of ice, by volume.
We have been taking comfort from the fact that volume rebounded in 2013/14. What we may be overlooking is the distribution of that volume is highly asymmetric.
We have coverage in the ESS, Laptev, Chukchi and Kara, but not the volume it needs to survive. We have volume in the CAB, but also know *that*ice is not uniform. Winter and current export through the Fram has thinned ice north and east of the Barents considerably. Most of our saved volume is in the CAB, and I'd wager over half that is smashed up within 400 KM of the CAA. That certainly won't melt out, and we may see disconnected "islands" of MYI surviving in the CAB and Beaufort. Trace out where you see ice 1.75 or thinner, and I suspect that will be close to showing us what will disappear. We may still end up with more volume and area than 2012, but less extent.
Another thought to ponder; heat continued well into October last season, with peripheral melt happening after minimum even as portions of the CAB started re freezing. Will increased seasonal heat and El Niño conspire to extend the active melt for a later minimum?
I'm in Chris Reynolds camp; one good smash is all it would take to change the story being played out.
My metaphor for you - it's like watching a high wire walker trying to cross Niagra falls in a windstorm without either pole or net. Getting to the other side (of the melt season) intact is more a matter of luck than it is dependent on the current state of things.
One good gust (smash)....
