ATL: ISAAC - Post-Tropical - Discussion

[SoupBone]

As per the NHC landfall at the mouth of the river

Not that due to satellite parallax, the center is near the southern edge of the eyewall. Not close to landfall yet. Oh, and where exactly does land begin in southeast Louisiana? I generally consider it to be around I-10, and sometimes north of there.

I'm curious how long it takes for upwelling to occur in the depth of water he's in right now. Just a curious question.

why is everyone posting about western movement and stalling...that is not what the NHC has been forecasting, it has hit the track pretty much dead on (les than three days out) why such a low confidence now in the track from many of you?

Lets keep the comments on topic please.

because we saw the last 2 runs of the GFS and NAM models....thats probably it....

Um, no. As wxman57 pointed out earlier, the center of Isaac is south of the dry spot some are perceiving as the center of circulation.

57....land in Louisiana starts when you see the first reed of marsh grass....

Isaac still looks on track to me.....headed towards the south-west pass......MGC

I feel like i've seen this before, the mod who posted the Recon image shows a different tale, perhaps actually is it trending north?

I think she was using recon to pinpoint center.. as it relates to NHC forcast... I agree with her.. I think recon is the best media right not to determine center.. my humble on untrained opinion only... NHC has done a pretty good job regarding the track of this storm ...

meant to say recon best method TO determine center attm

Does this mean NHC forecast point is wrong?

Zooming in on this image, you can see the constant explosion of thunderstorms. Yeah, I'd say about right there.

The long range radar on impactweather.com shows what looks like movement just south of west over the last two hours. It could just be the radar showing an optical illusion as well.

from the looks of that sat photo the bands are all the way up to IN

The center is rotating around a fixed point, or wobbling around, as convection builds. So at any point in time you may see it moving NE, NW, SW, SE. Overall motion continues to be generally NW.

Looks like that to me too, southwest. Welcome to the wobble watchers club.
