Cat 5s are rare, so, A rare even followed by a rare event.... is .... even more rare. (Very Rare on the Encounter table) However we only have a fairly short timeframe, climatologicly speaking, to work with.

There could have been more Cat 5 storms before the 1960's and unless a ship or hurricane was unlucky enough to be in the way of it, we wouldn't know.

I don't think there's been 2 cat 5's in the atlantic basin within a month of each other in the last 40 years or so. But I'm sure the pacific basin has them happen from time to time (wow that was a convoluted sentence...).

Also, since 95, we've been in an active period in the atlantic. So, who knows, maybe we'll be unlucky enough to have this become a more common event for the next 20 years or so.
