ATL: IOTA - Remnants - Discussion

[kevin]

Now 916.7 mbar with 20 kt SFMR at the lowest pressure measurement, next update should give data on the NW eyewall.

The eye is getting smaller

Looks like Iota is still deepening, albeit very slowly. Extrapolated pressures have dropped around 2 mbar between the first and third passes.

SFMR readings in the SW eyewall are pretty impressive. upper-CAT4 sustained winds in all quadrants

Weren’t they ~914 on this morning’s mission? I believe it’s just been holding station for a few hours.

AF305 is on the runway.

Extrapolated pressures were down to 913 mbar, although dropsondes only got down to 917-918 mbar.

Based on what?

I believe the storm weakened between the 2recon flights before restrenghtening again. The ir suggested a kind of structural issue or small change with a gap on the southern part of the cdo before showing the compact - cold cdo we are looking at right now.

Increasingly impressive appearance but can't imagine it gets too much stronger; it's already at unprecedented intensity for this late in the season and still feels absolutely surreal lol

Yes, so about the same as now...

I forgot the image!
Only 1 wind barb is below 10 knots

[aspen]

Seems like recon missed the NW/WNW quad.

Lack of SFMR or FL wind data to support 140 kts would indicate this is no longer Cat 5. Still an incredibly intense high-end Category 4.

They literally went NW from the eye...

[supercane4867]

Somehow the strongest winds have all been found in the southern side of the eyewall. Interesting for a west moving system.

Good. We got a crazy, record breaking storm... now I hope it implodes before landfall. They need a break down there.

How does that indicate anything about the eye getting smaller? It’s already on the small side anyway.

It can get slightly smaller or larger over time right now.
