The new (11 pm PDT) advisory has the intensity at 944 mb/125 kt, which sounds right to me.

P.S. I wish folks would attach some of the porn rather than linking it-- to ensure we have some of these images for posterity. It only takes an extra second to do that.

mine will never be deleted...i have an actual account at imgur.

attaching is annoying and sucks up my finite space

Phil is lurking. I wonder what he's thinking Re: landfall prospects down the road. Perhaps he might indulge me with some thoughts.

Of course I'm under no illusion that this thing of beauty would come ashore in six days looking so exquisitely perfect as it does now. I'd be surprised if it looks this good tomorrow, to be perfectly frank. Cat-4 microcanes are inherently delicate, ephemeral creations. But I wonder if it might come ashore in some other worthy form-- like a larger, less fancy 'cane.

Best weather event going on by far right now. As well as the best looking cane on this side of the Hemisphere this year.

I agree with Josh however.... not sure how this will look once it gets closer to the cooler waters and not as favorable environment once it begins the hook north.. Safe to say it will peak soon...... and probably hold steady for a bit before eye wall cycles kick in and gradually cooling waters as it turns more toward the north.

Just have to wait and see how sharp this thing hooks.. more gradual less threatening... . :X

Agreed. The earlier and the sharper the hook, the more threatening this will be to MX. It looks like the models are reaching a sort of broad consensus that it will eventually head toward the coast, but of course they disagree greatly Re: timing, intensity, and latitude of landfall.

Yea I'm pretty sure Hilary is reaching it's peak intensity this morning. If that eye cools just a touch more, 140 knots is not out of the question.

It's beyond that's obviously the most interesting, from a landfall perspective. While this system is certainly deep, it's also very small in overall area, so it's having a smaller influence on the synoptic features than say what Irene or Katia had in the Atlantic even though both of those systems were weaker. With that said, I'm still in support of the storm aiding to create the weakness in the 500mb ridge as it increases in size over the next 3 days due to EWRCs. The ECWMF seems to have a good handle of this. The problem is that while the ridge breaks down enough north of Hilary to turn it NE, the ridge does not collapse all the way in the east pacific west of the system so the storm is slowed to a craw as it moves NE. This could allow for upwelling and shear to do a number to the intensity. We still need not only a further south track than the ECWMF but also a faster one as well to allow this system to have the chance as a landfalling major Hurricane. That would only happen if a much deeper trough picks up Hilary or a stronger piece of the ridge develops southeast of the system rather than remaining northwest.

All makes sense. So what's your long-range call? Does it come ashore in MX? If so, on the Baja or on the mainland? And how strong?

Lemme guess-- a weakening 80 kt on the Baja? :D

I'm generally leaning towards a Baja Impact. Intensity is very tricky as it seems most of the weakening will be thermodynamically driven. 80 knots might actually be on the high end, especially if it stalls and drifts for 48 hours or so like the ECWMF suggests.
