rapid scan close up loop.

Wow, thanks for sharing that link. Looks like it's really starting to expand.

Agreed...this has slown way down.

Not sure why people are sounding the death knell for Isaac. It's exploding ATM.

It's because the NHC and TWC mets are downplaying the intensity forecast. Seems a bit dangerous to me when you think about all the storms that have bombed in the GOM.

[galaxy401]

you have to wonder if a storm this year will have a central core.

Yeah, I know. It's almost as if the southern Atlantic, Caribbean, and Gulf of Mexico are just to hostile these days for any cyclone to become a major hurricane. 2005 really did spoil us.

im still wondering if isaac can set a record for the longest lived TS that never became a cane. its been so long since the GOM produced anything other than sloppy messes.

Uh the record is about two weeks. Isaac hasn't even existed a week yet...

Does slower mean possible farther west?

I made a poll about landfall intensity in Northern Gulf Coast. Go and vote at the Contest forum.Here is the link to the poll.

Doesn't slowing down sometimes happen just before a change in direction?

[psyclone]

I suspect the NHC's tempered intensity estimate may have to do with the size of the system (as well as its inability to intesify thus far). big storms take longer to change intensity in either direction. i sure would not write this storm off on the northern gulf coast. in fact, i would be channeling the energy of anxiety and fear into constructive preparations.

Is he larger than average? He appears so to me, but I can find nothing about his size, just intensity.

I dont' know if I've read any posts giving it the death knell...I still think it will make it to hurricane strength before land fall in spite of it's large structure.

[Janie2006]

I think it's really difficult to estimate an average size for a tropical system. They can be rather small and intense (Camille) or really, really large (Katrina). In my estimation Isaac isn't all that "large" so to speak, but if he intensifies you'll see that wind field expand accordingly.

saw this on twitter....Where Katrina was 7 years ago today...

Looks better then it ever has, in my opinion. The people saying it looks awful must not be looking at Isaac. Should start to get going even more in the short term, and could be much stronger then 100MPH in the long term. Everyone needs to be completing their hurricane preparations, and prepare for AT LEAST a low end category two.

This storm is HUGE. If it continues to expand it could end up larger then Kartina IMO

i agree it wont be hard for it to get to 75 mph, but it needs to put the brakes on for anything more than that.

Important question, as slow as this thing goes through the east texas/north louisiana area as depicted on the 12z and 18z GFS today, what kind of rainfall are we talking about for that general area?

[northjaxpro]

saw this on twitter....Where Katrina was 7 years ago today...

That is very spooky to say the least. Isaac is currently almost exactly in the same spot where Katrina was at this precise time seven years ago on this day. THe only major difference is that Katrina was a cat 2 hurricane at this point, while Isaac is currently a 60 mph TS.

BTW, this loop makes it look like it is on a 270 heading at the moment...
