Looks like Fiona is intensifying again. Waiting for Recon data.

Re: ATL: FIONA - Hurricane - Discussion
Either Fiona has a poor pressure gradient, or she's a very strong storm because Recon is barely inside the storm and the extrapolated pressure is already below 1000 mb.

Re: ATL: FIONA - Hurricane - Discussion
Extrapolated pressure is the same as last flight. Strangely, the NW quadrant has zero FL winds above 90 kt. Maybe another EWRC is about to commence?

Most recent Microwave shows a semi open southern eyewall. Something is going on.

Reminds me of Hurricane Teddy near its peak, with Cat 4 FL winds but abnormally low SFMR. They even look similar too.

Re: ATL: FIONA - Hurricane - Discussion
Seems to be a common behavior for large hurricanes that are gaining latitude in the open Atlantic. Pressure can still drop to low levels but wind speed doesn't seem to increase at all.

Re: ATL: FIONA - Hurricane - Discussion
If Y'all are wondering why the NW Eyewall dropsonde winds are only 40 knots is because they just missed the strongest winds and the location is the outer edge of the eye.

I've noticed that Recon has a double wind maxima reading on the SMFR.

I dunno, if there’s any at all it’s pretty minuscule. Looks more like a storm that’s been dealing with shear all day

VDM has Fiona's eye open to the SE, and it's at 935 mb. Maybe an EWRC or something weird? Idk

Re: ATL: FIONA - Hurricane - Discussion
This buoy should provide some interesting data. Winds are already above 40kts.

Probably a combination of slight/moderate shear eroding the SE eyewall, and an EWRC trying to start again. There are multiple double wind maxima seen on this flight.
