ATL: IRMA - Post-Tropical - Discussion

[Aric Dunn]

I wonder if a EWRC was kicking off and the new outer wall, being on the NE side of the CoC, got caught up in the updraft of the poleward outflow channel thus kicking off a self-sustaining MCS.
If this is one of those twin systems, it'll be the third time I have seen it and the MCS is nearly always on the NE side.

well according the last 2 microwave passes over the last 6 hours.. a ERC does appear to have started about 7 hours ago.. though its not happening nearly as fast.

Looking pretty rough in that image?

typcical of a ERC

That EWRC looks nowhere near close to finished

[NotSparta]

It's #3, Irma is the ultimate ERC producer

[Jimsot]

Now that its moving over warmer water and higher OHC, I believe that once EWRC #2 finishes, it will take off. NOT a pro forecast.

Is it #2 or #3, I thought she went through one early this morning.

Is that 3 wind maxima. I am afraid I do not know how to read that display.

Hurricane Fernanda would have a problem with this statement.

[Yellow Evan]

It's CDO looks colder than it did yesterday. Good sign for upcoming days for further deepening.

[Alyono]

that's not an EWRC. Maybe some slight mid level shear

[msbee]

That 5 PM advisory is making me nervous, Cycloneye

Getting much closer to Anguilla and St. Martin as well.

Yes,is getting serious now but still there is time for changes for the track to lift north.

It looks like they are going to stop the ferries Monday afternoon and move them to San Juan

Microwave imagery shows a big hook of dry air wrapping towards the core. Looks like a probable ailment to me.

[Blown Away]

Irma starting to dive very close to SW now, maybe @240 heading...

[Emmett_Brown]

Just an observation, not based on science, but just experience watching hurricanes. When a storm is being forced S of due W, sometimes that S motion component persists longer than forecast. We saw this with Katrina over FL and Ike over Cuba for example... both were delayed in resuming a W and WNW direction. Not saying this setup is the same, but I hope for the sake of those in the islands that Irma doesn't delay her turn back W and WNW.

WPC's position Day 7...

Hey everyone! Haven't posted in quite a while but still lurk frequently. Wanted to let everyone in PR and the northern islands know that my thoughts and prayers are with you. The trend is definitely not comforting for these areas. You all are often overlooked by the media and others. Just wanted to know that I am thinking of you.

I would not be so sure. I have undergone a lot. Though admittedly most of mine are due to people getting my eyeglass prescriptions wrong.
