Cat 4. Matches recon data.

[cycloneye]

Yes it matches well.

What is frightening is the ability Ivan has to go through dramatic strengthening cycles. WIth a
hot Carribean and a hot GOM, this monster may be
the infamous "next big one"

Who wants to win that lottery?

[canegrl04]

Ivan seems to be able to go through strengthening cycles faster than Frances did.
