dan11295 Posted September 27 Share Posted September 27 Definitely will not be weakening upon landfall. As has been stated by the NHC and others, Helene will have major inland wind impacts. Combination of strengthening large storm and rapid movement. EDIT: That dropsonde might justify an upgrade to 120 kts. Link to comment Share on other sites More sharing options...

MarkO Posted September 27 Share Posted September 27 Cedar Key area got to be experiencing some surge now. Wonder what it's going to look like in the morning. I hope everybody there evacuated. Link to comment Share on other sites More sharing options...

Power flashes already occurring a few miles south of Tallahassee. This area hasn't had this type of storm in AGES... There will be unusually severe tree and infrastructure damage in areas that haven't recieved these conditions recently. Link to comment Share on other sites More sharing options...
MN Transplant Posted September 27 Share Posted September 27 It is amazing how close this will end up being to Idalia’s landfall (Keaton Beach, south of Perry) Link to comment Share on other sites More sharing options...

The eye started as nascent than made its way through the stages and in doing so there was the reorganization of the core & CDO. Not the true ERC’s we see with more developed, substantial canes. 1 1 Link to comment Share on other sites More sharing options...

csnavywx Posted September 27 Share Posted September 27 33 minutes ago, BTRWx's Thanks Giving said: I wonder if that outer rain band to the southwest of the center is slowly becoming the new eyewall. It's basically out of time here, but if this were still well out over water, then this is the kind of setup that could eventually result in an EWRC. The series of mesovort formations and mergers we've been getting usually precedes cocentric band formation -- so you could argue we're getting ready to enter the incipient phase of one. 6 1 Link to comment Share on other sites More sharing options...

dseagull Posted September 27 Share Posted September 27 NOAA got a 941.8 reading, and now looping again. Wonder 8f it's broken again. 940.2 from TEAL. 2 Link to comment Share on other sites More sharing options...
Amped Posted September 27 Share Posted September 27 Pretty steady now. Radar seems to show a wobble to the west the last few frames, puts it back on course to go straight over Perry. 2 Link to comment Share on other sites More sharing options...

dseagull Posted September 27 Share Posted September 27 Should find out shortly. They just reported 160mph flight level winds. They are sampling again. Communication between their reports and NOAA seemed confusing. Link to comment Share on other sites More sharing options...

I believe it happened once before where they had to fly around in the eye and wait for another mission to look over the aircraft on a flyby because of mechanical issues.
