ATL: ISAAC - Post-Tropical - Discussion

[PTrackerLA]

In my opinion Isaac has never looked better on satellite. Don't think it will be too hard for him to make a run at 90mph but we'll see.

[KWT]

I'm going by satellite appearance only, and the fact the northern edge of the storm has eroded compared to earlier. No doubt I could be very very wrong. Wouldn't be the first time.

I do sort of see what your seeing, I don't think its done dealing with dry air yet though it is looking better now it has tucked into the CDO pretty centrally, big improvement in the shape of the system over the past 6-9hrs.

[Time_Zone]

In the hour by hour saga that is Isaac. Recon found no eyewall, last pass, now it appears lots of dry air is being entrained into the circulation. Hopefully this is a good sign that intensity will continue to be lower than expected, but a pro will need to evaluate first.

Gonna have to disagree. I think Isaac looks to FINALLY be getting his act together and his dry air problems look to be behind him for now. Though, we know Isaac loves his dry air so that could change easily.

Has recon confirmed the movement?

[JamesCaneTracker]

lol the latest Wind shift that Recon went through is North-East of the last Center Fix... It's possible the center is still doing Loops around in the CDO...

[Aric Dunn]

center being pulled around recon found it nne of the last pass.

Looks to be deepening quite fast now.

The pressure is still dropping at the buoy it passed directly over a couple of hours ago.

Lowest pressure recorded was 985.3 mb with winds around 35kt.

good outflow to the west occuring...I saw some high clouds come over my house...

An interesting ring around the sun over here at Stennis Space Center... no I didn't look right at it

[Texashawk]

I think this is just one of those storms where you've got to look at the whole circulation instead of just the LLC. It's a weird storm, to be sure.

Man they just can't get from under that rainband, maybe when the sun goes down it'll lighten up. Stay Safe Fla.

palm beach county schools closed tomorrow..those kids went from school being open today per the announcement yesterday then closed today and now day two

new flt level center 11 nm NNE of last VDM... Time: 19:30:30Z Coordinates: 26.2333N 85.9333W.. waiting on dropsonde data

[tropicwatch]

I have been watching the satellite and didn't think there had been much movement over the past hour or so. Isaac might be taking a breather.

[Bluefrog]

what exactly does that mean stormhunter7

[JamesCaneTracker]

new flt level center 11 nm NNE of last VDM... Time: 19:30:30Z Coordinates: 26.2333N 85.9333W.. waiting on dropsonde data

Don't think it's a "new" center just that the center is doing loops with in the convection or as Aric said the center is being pulled up under the deepest convection...

With a Pressure of 985mb or below I would be very surprised if it was a whole new center.

[capepoint]

While they may or may not see winds over about 80 mph, the people in lower MS and AL better be ready for some serious flooding issues. I think that is what will be the legacy of Issac.

I would wager that a meso is in the process of forming a large eye -- "marble in a bowl".

[rockyman]

Boy, Isaac has suddenly put on the brakes! I'm guessing that this is all just part of the "organizing process"...none of the models show a stall out in the Gulf.

[cheezyWXguy]

I may be wrong but I believe the first signs of an eye may be showing up on vis now.

Am I missing something? Where is this surge of dry air? If anything, it is becoming miniscule of a factor. I don't see this thing doing anything but intensifying.

I'm going by satellite appearance only, and the fact the northern edge of the storm has eroded compared to earlier. No doubt I could be very very wrong. Wouldn't be the first time.

I think you're right. It's struggled to expel the dry air it ingested yesterday and early this morning. The shear this morning didn't help.

There's been so many posters the last 30 hours talking about how it's going to bomb, it's going to RI, etc etc, everytime there's a dab of convection.

There's no doubt the environment is slowly becoming more favorable. But it's struggled with dry air, the circulation is huge and while the pressure is slowly dropping it doesn't appear to be on the verge of a "blow up". We'll see beyond 6 hours what the environment looks like and if the ULL is going ot move off to the west as predicted.

It is to the point now most of that dry air should be mixed out within the next few hours, assuming of course there's not much else going ot be ingested it can intensify and probably will. But people expecting RI are probably not going to see it.

No eye wall...so no eye. The only thing i'm seeing from that loop is Isaac is once again...eating dry air LOL
