(1/3) #Michael at landfall. The normal "stadium effect" was more like a cylinder, a straight vertical wall 50K ft high. Saw 175 mph flight level winds, ~155 mph at surface. Entered eyewall at 10K ft, ended up in eye down at 8K! Need another tweet to explain what that felt like…

Just a tropical #wxtwitter PSA, but there is no substitute for in-situ data provided by @53rdWRS. Compare ASCAT-B vs. HDOBs from the current recon mission in #Peter. Without recon, one could conclude the vortex is an open wave. For sfc winds, In-situ obs >> remote-sensing obs.

Really good article from Allison, on what can be a really confusing topic…making sense of our wacky flight patterns! Believe it or not, there is a purpose for each.
It's a star... it's a box... no it's the pattern of a plane flying through a #hurricane! Thanks to @JeremyDeHart53d and @TheAstroNick for the insight into their challenging, but crucial jobs. cnn.com/2021/09/19/weather/w…

After reduction to the official measurement height of 10 m, this would still rank as one of the highest surface gusts ever measured in a hurricane. Record: 211 mph, Hurricane Gustav, 2008, Cuba. 2nd place: 186 mph, Long Island Express Hurricane, Blue Hill Observatory, MA, 1938.
Port Fourchon submitted data from the Laney Chouest. A peak gusts was recorded at 194 knots, 223 mph. This was at a height of 100’ and an instantaneous gusts so there will be some reduction. Ida post-analysis will look at this for Cat 5 designation.

Rainfall threat from Nicholas is far from over, as the forecast now calls for it to stall over Louisiana. It wouldn’t be surprising at all to see the event maximum rainfall well displaced from the landfall point, somewhere over Louisiana or even far southern Mississippi.

Really just fascinating dynamics with #Nicholas we have been able to watch via KBRO radar today. First there was the center reformation last night. Now, two distinct vorticity maxima are rotating about a common axis. Net result: Nicholas is reorganizing as it pivots NNE. #TXwx

We've got our work cut out for us with this one. Chasing multiple competing centers is one of the hardest things the weather officer has to do. #Nicholas @53rdWRS
Off we go again, #Nicholas now trying to build an inner core under the most intense thunderstorm activity but the dry air has caught onto the plan and is now moving into position for another disruption. This cat-and-mouse game will continue so long as Nicholas is over water.

Finally had the perfect reason to make it to Starkville/Miss St. (thanks for the tix @wrsimmons). Great vibe & gracious hosts. On-brand Wolfpack performance, but still had fun. Most exciting play of the day was me photobombing the Meteorology building. #GoPack

Also saw an awesome C-17 flyover from Jackson ANG. Pretty special on the 20th anniversary of 9/11. #NeverForget

Latest VDM from @53rdWRS mission indicates Hurricane #Larry no longer has a defined eyewall and the central pressure rose 3-4 mb between passes. Clear weakening trend.

With the forecast cone continuing to trend east of Bermuda, this could be the best case recon scenario - a strong hurricane with minimal impact but lots of great eye candy. Looking forward to seeing some great imagery from the crews this week! #Larry
We’ve sent a few aircraft and crews to St. Croix to fly fixes into Hurricane #Larry beginning early Tuesday morning. #ReserveReady

Another vantage point of ongoing absurd rainfall rates in NYC metro from #Ida remnants. #USOpen play suspended at Louis Armstrong Stadium which is INDOOR. Has a roof but is open air in upper deck, so this rain is coming from in the SIDES. Just insane!
Armstrong right now #USOpen

Meanwhile, play still ongoing at Arthur Ashe Stadium which is completely enclosed. But this is what it looks like outside the stadium 😳

Truly remarkable time lapse video from our remote cam that was set up in Laplace, LA at Frenier Landing to capture the storm surge from hurricane #Ida @BuzzFeedStorm @afreedma @capitalweather

Of all the Ida landfall videos I saw from yesterday, this one stood out. Sound up. Watch the full FB video if you have time. Experienced a similar eerie howling while riding out Zeta overnight last year, but about half as intense. It's the roar that always gets me with these.
With the help of wxtwitter, I found some footage of what looks like Grand Isle, LA experiencing Ida’s inner eyewall. It sounds terrifying. You can view the whole live video here: facebook.com/raymond.serigny…

WOW. Ship at Port Fourchon reported sustained wind of 149 mph and a gust to 172 mph. #Ida #LAwx

This visualisation was built exclusively from recon data using a program called #Tropycal, created by @burgwx and @splillo. Really just a fantastic tool!
Replying to @burgwx
The data that comes out of these recon missions is crucial for all sorts of purposes, from research to real-time storm intensity and structure assessment. Here's a sample of the data collected here - we can see #Ida formed a compact inner core while rapidly intensifying.
