Take a look now...

MY guess is that when that plane gets in there, we will find that Rita is a Cat 5 with 160 MPH winds....
Last report (which was an estimate, cause they didn't get to do the earlier flight) says it looks like winds of 140...so saying 160 is not out of the question...
I'm not a meteorologist, just someone who has a hurricane hobby, but I still don't think she looks like an annular hurricane. The annular hurricanes that I have looked at look more like buzzsaw blades. Give her a couple more hours and perhaps her outflow bands will balance out to give us a better look. One thing that is sort of creepy is that I haven't heard of an eyewall replacement cycle for a while. That certainly isn't a good sign (as annular hurricanes don't need to replace their eyewalls).
