Is that the giant outer eyewall or just a dry slot?

[Sciencerocks]

I am betting that shear is inducing dry in into the core kind of like hurricane Ike of 2008 and that will allow for bigger and bigger eyes. I doubt this will ever get much stronger.

It is a massive eyewall. Approximately 100 miles in Diameter. Nhc puts it at a 50m radius which would make it 100m diameter. Absolutely tremendous storm in size. RMW is going to be huge.

I also feel that Larry was a Cat 4 early this morning. back when it had a black ring and 20C eye temp.

[USTropics]

When the eyewall diameter distance is so large even the mesoscale models can pick up on the stable mid-level air at the center:

Gigantic eyewall emerging...

[InfernoFlameCat]

Anyone else know of an Atlantic storm with a true eye that big? Teddy tried and failed but any others? I know Wpac had some monster eyes like Winnie carmen and Trami but what about the Atlantic?

[Hypercane_Kyle]

Larry really going for an epic eye with this ongoing EWRC.

[Stormybajan]

Hurricane Larry is looking unique right now. Looks like a eyewall replacement cycle has been or is about to be completed but the inner eyewall just,wont,die! . If that eye clears it would be one of the largest eyes I've seen in the Atlantic

I'm excited to see how this looks in the morning! It's been a bumpy ride these past few days for Larry, but it looks like it'll pay off very soon...

[Hypercane_Kyle]

Rapid cooling of the CDO occurring now.

[Yellow Evan]

I see this struggling going forward to wrap around convection due to its large size, and even when it does, winds will likely lag behind its satellite presentation.

Looks like all the eyewalls are finally merging

Delta had a gigantic eye, nearly 80 miles, with Port Arthur and Lafayette in the eyewall at the same time... but this is truly next level.

[Yellow Evan]

T5.0.

[grapealcoholic]

Looking like it might get to Cat 4 by 5am
