  The storm cch001 and I have been discussing gets more strange a few hours later. This one is cool but I would not know how to classify it!

  #concentric-eyewalls - I would classify as an #eye-storm, with the size of the eye determined by the inner one. Fascinating image.

  Is this something that hurricanes do every now and again? Is this part of the eye-wall replacement cycle?

  This is a really odd image which is why I flagged it. Replacement cycles are fairly common but not clear that this is one or not.

  There is so much space between the two sets of cold cloudtops it could be more complicated than a simple replacement cycle.

  I think this particular image should get researched more in-depth, to find out what exactly is happening.

  Yes, this is a snapshot of the middle of an eyewall replacement cycle. Normally the inner eye will dissipate and the outer will contract

  It is fairly common in very strong tropical cylcones

  A lot has been written about this particular storm, e.g.: http://tinyurl.com/k2g94kj and it is the poster child for the Wikipedia entry
