Heh, whoops, you reposted after I put in my answer, so a copy from the other thread:
The problem with the hurricane name is that people don't always mean the same thing when using it. Don Soderburg at South Mountain Reptiles has some of the prettiest "hurricane" motleys you'll ever see. By hurricane, he means having darker color around the circles (like the eye of the storm) with the lighter color in the rest of the saddle.
Picture directly from SMR website:
Hurricane Snow Motley. See the extra color around the circles?
Another picture directly from SMR website:
Non-hurricane Snow Motley, saddle coloration is more or less even.
Other people have taken "hurricane" to mean fully circle-backed, not the pattern of having dark around the eye like a hurricane, where the term was originally derived from. That is where the confusion has come from. It's unfortunate that there isn't a good term for the perfectly patterned full circle-backed motleys that many strive for. I think it would reduce confusion. I put a thread up about that once, but the response was minimal, so we're left with explaining it every time.
