CPAC: ISELLE - Post-Tropical

[JtSmarts]

I hope flooding doesn't become a huge issue with Iselle slowing down so much.

Great point. This is very dangerous. Never thought of it, but landslides are a serious hazard if it continues to stall.

It's a good thing that at the moment it appears that Julio's core will remain a good bit north. That could make things so much worse.

Recon fix confirms center is now at almost the exact same latitude with south point
Pressure up to 1000mb...this may even die off before reaching land

So much for a hurricane. Iselle has rapidly weakened and losing it's circulation. I think the big threat is flooding.

Could it open up to a wave?

It's losing convection but not circulation yet and wind field is nowhere close to a tropical wave
Otherwise it will take a long time for the vigorous LLC to spinning down

[Kingarabian]

10mph per hour, 40 miles away from land. Tonight.

[TheStormExpert]

Now I feel like I'm over on the Atlantic side with talk of an open wave.

[supercane4867]

Last loop before off to bed...hopefully I see landfall declared when wake up a few hours later

1 Quadrant is all ready over land has been for quite some time now.

Iselle is rapidly collapsing. Winds on Mauna Kea also have dropped to 51mph sustained. The low level circulation remains vigorous however, and the heavy rainfall continues.

Whoa I just had a major Deja Vu guys, I started at this post after viewing imagery and then scrolled up to read everything as it was sometime before and the exact order of users that posted each post all the way to the top . It was as if the structure eariler this year of how a discussion flowed and the current state of the activity in the basin was a perfect match to maybe something in May or last year? All I know is this was the most striking one in years...

Recon fix confirms center is now at almost the exact same latitude with south point
Pressure up to 1000mb...this may even die off before reaching land

I thought something like this may be possible but I forgot how tropical cyclones almost are blocked from moving when dealing with terrain like this. Watching satellite loops is amusing of this stoppage. Looks like an arc band bowing towards Hawaii.

:uarrow: Now I feel like I'm over on the Atlantic side with talk of an open wave.

Same. When I get disappointed in any basin, I'm reminded of the ATL. The Atlantic is a place where dreams die now .

[NDG]

Wow!!!! What in the world happened to Iselle, lol.
Of course I know, just being sarcastic

Hawaii's Gods decapitated the heck out of it, lol.

[somethingfunny]

Flooding is occurring west of Hilo...

Where are the pro mets - seems they disappeared once the warnings were issued, so just a guess but perhaps its a liability concern because they are at the professional level - just a thought because professionals today of any type are wary of saying too much in on-line forums for that reason, which is unfortunate but true. My former supervisor is a pro met and in his retirement is a consultant, but that is done on the client level and the legalities for his work are different than sharing his expertise on the internet, so again it might be a legal restraint in this case that causes them to have to take a step back in a sense, because they are aware of that risk as a professional - unfortunate but its the world we live in. In this case the system has become shallow and is impeded by the mountain so serious flooding potential exists as shown in the NOAA graph that was posted on this page...

[AdamFirst]

A lot of rain and moisture is behind the core...unfortunately the big island is nowhere near done with the rain threat.

[WeatherGuesser]

Maybe they just went to bed.

No conspiracy required.

[Frank2]

No conspiracy intended, but having worked for pro mets for a long time they have a professional standard like any other profession that they must abide by and that includes their being cautious when posting to social media. That's why we can never get medical advice from a doctor over the internet, or messgae board advice from any other profession for that matter...

P.S. I'm concerned about the Big Island - serious situation there...

[Equilibrium]

Think a few people here took a look at a weak looking satellite pic and may have under estimated this storms strength wont be surprised to see a lot of wind damage in the final wash up.
