It appears the eye is starting to clear

Looking good with some nice ventilation going on even in the SW quadrent. Has about 24 hours to maximize itself before shear starts to really impinge.

Last recon pass is up 2 mb to 978mb. Never seen a strengthening storm that doesn't lose any pressure for 5 hours ...

I don’t think that’s a legit eye, IR suggests that the inner core convection still isn’t organized enough yet to pop one. Pause in strengthening for now, let’s see if Isaias can get going again soon.

Looks like it's struggling. What else do you expect from #2026?

Yep I was going to say the same thing... It just cannot keep the convection going.... every time it gets a burst, it fizzles out.

[cardinalland]

It’s passing over some slightly cooler SSTs right now

[ROOSTA]

I don't see an "EYE". Just hallucinations with convection sheared well to the NE. 

I named this sat capture as GONZO 

[eyewall]

Cloud tops warmed pretty quick. This system is definitely struggling right now.

Been on the same pattern since yesterday of convection really dying off during diurnal minimum but coming back with a vengeance overnight

That’s good news if it holds for those threatened. Hopefully shear will do its thing and keep it struggling. But it looks like it will probably still be a hurricane when it comes in and thus be no picnic for them.

I would think tonight’s its last chance to ramp up. It’s clearly struggling already with dry air and shear. Looks elongated already.

Looks like a legit eye to me but it’s only cleared out bc the convection waned and isn’t overshooting it from the SW I believe. Looks legit now

Recon seems supportive of 80 kts, closing in on cat 2 at a much more modest rate today

I would expect one more significant ramp up tonight before it hits the shredder Tommorow 

[cptcatz]

Looks like it's trying to wrap some deep convection around the west side of the eye. If it can hold on and build an eyewall out of this, that's it's shot.

Yep. Core is there and it will be moving over slightly warmer waters too. Diurnal max will be the max for this system. Imo 95-105 kts is attainable
