Teddy may be performing an “inside out” ERC. Can anyone think of any other storms that built a brand new inner eyewall that forced an outer eyewall to collapse? I can’t think of any. This seems like a potentially rare and unique event. I’m eager to see new microwave passes to see what is going on.
ERCs pretty much always work from the outer eyewall choking off the inner. I’ve seen inner remnants put up a fight and keep firing new convection for awhile, but microwave from a few hours ago suggests the old inner eyewall was completely dead, bones had been called. This seems like a brand new eyewall is forming inside the outer one. This season continues to try to do it all.
Actually a Met in a Discord said that angular cyclones (Which is what Teddy was before everything came crash down) have a specific kind of EWRC where the very large eyewall caves in on itself and forms a smaller more Standard Eyewall. This may have just happened. I think what is confusing people is that Angular cyclones are very rare (Last one I remember in the Atlantic was Isabell) so witnessing something like this is crazy. I'm waiting for a Update to this http://tropic.ssec.wisc.edu/real-time/mimtc/2020_20L/web/displayGifsBy12hr_08.html to confirm. This is going to be studied no doubt
Thank you for posting that info. Interesting. I have some reading to do it seems.
Do you happen to know if this is a phenomenon that occurs with a greater frequency in other basins?
