Is this normal?

Do major hurricanes usually spit out huge outflow boundaries from the center?

Interesting...some light shear over him is giving the idea that its moving WNW when it pretty well west right now. The center is actually to the SW of the "hole" since the eye is partially obscured, so you're seeing the banding as it heads off to just north of west.

Now THAT is one awesome gust front !

have to admit I also noticed that feature on last nights pics too! never seen one on a hurricane before

That's the second time it's happened in Fabian's case though the outflow boundary is coming from the outer periphery of the hurricane, not the center.

Yesterday, another large boundary or arc cloud blasted out of there, though it sure really hasn't hurt Fabian.

I popped open McIDAS and snapped a shot of it. Could be the squalls on the west side collapsed earlier. They appear to be rebuilding as you can see on this image:

Man, that's awesome looking!!

That's really fascinating since I always thought outflow boundaries were really bad to see for tropical systems.

actually the latest on Fabian shows that outflow feature developing further around the storm to the NW of the storm??
