ATL: IDA - Remnants - Discussion

[Iceresistance]

AF305 may be higher up, but it has picked up a sharp pressure difference from the NW . . .

[Kazmit]

AF plane just reached the center, looks like the pressure has fallen to 985 mb

Here we go. CDO becoming more symmetrical and trying to clear an eye on IR. I think Ida is about to take off.

ADT is now at 4.5, so 977 mb and 77 kt. Of course recon has the most accurate data, but the increase in ADT is a clear indicator of Ida's improving organization. I was a bit surprised that the pressure is 'only' 985 mb, but I think it should start falling further soon. We'll find out whether it's still holding steady in terms of pressure during the next pass. Btw, will there be continuous recon in Ida from now on until landfall or what is the recon plan for the coming 2 days?

NHC forecasters seem all be thinking what we are... the structure is there, the winds and pressure will match soon

NOAA 3's Dropsonde in the eye might support 985 MB . . .

985 mb

Woke up to take a quick look at satelitte. IR and BD curve suggest to me that a pin point eye may now be developing. If so, get ready to watch Ida shed 20-30 mb's in the hours to come

That satellite image is something to behold

Dvorak numbers will skyrocket in the next few hours, I feel.

Well, well, here we go. Eye formation commences

The intermediate advisory has not been published yet. It is interesting to see what the NHC thinks now.

Looks like wind field is expanding which could mean additional watches/warnings.

[Owasso]

85mph/985mb for the intermediate

very impressive looking this morning, seems like recon got there in good timing, are they on 3 hour fixes yet?
