actually 129kt = 130mph surface. Definitely borderline, and wouldn't be surprised to see it upped to 135mph.

Seeing the latest IR imagery they would have been getting readings in the strongest convection on the northern Quad, something they have not been hitting.

Using the 90% reduction, 129 kt translates to 116-117 kt which is 135 mph...

I was about to post this before unmercifully, the power surged due to a light rain shower and 31 KT wind gusts ...

Note in the last two RECON FIXES ... how the SFC center is bobbing basically ...

EYE 0.7 MILE FROM S EYEWALL.

and the previous ...

EYE TUCKED 0.5 MILE FROM SW EYEWALL

Also the last advisory, the eye was 10 NM circular ...

NOW, it's elliptical ...

M. E05/13/9

and maybe why pressure leveled off ...

129 KT FL winds, though, in the N quad is some serious stuff ... using a 90% reduction (with intense convection) would equate to roughly 135 MPH MAX winds ...

If not Cat 4 at 8, I definately think it will be at 11pm. This could turn into a real monster. I still think this is the Tampa Bay monster! I only hope all of those who evacuated during Charley will heed the warning with Ivan.
