Tropical Major Hurricane Michael

I think given all the data this supports a cat 5 intensity for landfall. We have 152kts at FL, SFMR of 138kts which if you use the reduction of .9 for the FL winds would give 137kts at the surface. Spike in eye temp, continued pressure falls, radar briefly showing 190-200mph winds just 2-3k feet off the ground now... this is IMO a 160mph cat 5.

Also this ob the SFMR wasn't flagged it seems for the SFMR.

Even if they don't upgrade it now, I'm sure it'll probably be upgraded to cat 5 in post-analysis.
 
yep, just looked on pattern, looks like the car for Brett was officially fully submerged and the electronics were fried. Just pray he makes it with wherever he went for safety.

That 138 KT SFMR reading was flagged so I wouldn't be so sure about that. It's in a gray area but not conclusive evidence on its own of anything.

Yeah they have more things to worry about with all the impacts now spreading inland... I do think there's enough there to warrant an upgrade to cat 5 in the post-analysis of the storm. I hope everyone in the path will be okay...

The 152kts at FL using a .90 reduction would certainly support that reading along with the radar data I mentioned, eye temp spike, pressure drops, etc. I guess we will have to wait for the post season analysis on this one but in my book it is a cat 5 landfall.

That observation may have been contaminated though because it was so close to shore & it was raining, so I wouldn't use it outright on the spot to prove anything about whether this was a 4 or 5 without further investigation into that particular reading and SFMR itself (the latter is currently in the process of being reviewed and published in literature). Under sampling bias would be a more legitimate reason to consider upgrading if this observation isn't verified. All else considered it's a tough call but considering cat 5 starts at 136-137 KT and not 140 KT, I would agree we barely made it.
