NHC has the storm at 155mph now; only 1 mph off of Category 5. Recon found 155kt winds at flight level. No concentric eyewalls found this time. Pressure is back up to 918mb.
Are they flying at a different altitude than they've been flying? 155 * .9 (the deduction they've been using for Dean) = 139.5kts at the surface, which is 160.425mph according to my math. If I do an 80% reduction I only get 142mph at the surface (and 85% reduction gives 151mph).
Edit: Where are you seeing 918mb pressure? NHC link still shows 915, with the 155kt flight level winds.
