IMO there’s evidence this is already at cat 5. Radar, flight data, and satellite could all be used to say this is a 5. It’d close. I don’t think it’s done deepening yet either. 150 or 160, not terribly much difference. At least it missed the larger islands, those islands it did hit are likely shredded and will be uninhabitable after the storm for a long period. I hope everyone has safe shelter, I expect Irma-like images after the storm passes. As others have said, when you see these mesovortices you can get gusts much higher than the stated sustained wind. I have no doubt extreme winds well over cat 5 are being experienced at least in gusts. This storm is an absolute specimen. Hopefully we avoid loss of life
