it's actually getting smaller. it's going through another one of those, what we call eyewall replacement cycles, where there's a double eyewall right now. that outer eyewall is forming, that has a wider diameter than the inner eyewall. and it's contracting in towards the center. and normally what that does is it actually weakens the storm briefly. so what you might see overnight is you might see the hurricane bottom out in intensity, maybe weaken just a few millibars. but then once it completes that eyewall replacement cycle, it's right back to being even stronger than it was before. and irma has been amazing, because it's gone through about four or five of these cycles over the last few days. >> that's incredible to see. i appreciate all the work that you and all your colleagues are doing to keep us informed. richard henning, thank you.
