This will be studied for a long time. I have never seen a system maintain pressure like this while bouncing off the coast. It has to be upwelling those waters some too and he's getting some dry air in but Isaac doesn't care.

Coastal marshes is just pretty much close to been open water, I remember tropical storm Fay strengthening after it made landfall in the Everglades back in '08. BTW, I still see plenty of water temps in the low 80s near Timbalier Bay where it is located now, Grand Isle station still reporting 81 deg still.

He took in a good bit of dry air earlier, which beat up the NW quadrant. But, he just shook it out and reformed. Ironic, that while in the Gulf, the dry air was so hard for him to shake, and now it seems like it's not a hindrance at all. I'm really hoping this doesn't linger on for another 10 hours here in New Orleans. This is crazy!
A few days ago many were laughing at the Euro showing Isaac to be just about this strong as it reached the coast, wrong coast by the way, but nevertheless it show for it to strengthen but forecasters laughed at it, it was pretty right.

It is indeed another cyclonic loop, after the loop completes, from point to point is WNW in forward motion. Pressure up another millibar, but still this is a product of saying tropical storm Isaac for at least over 12 hours when realistically this was at least an 80MPH cane from noon yesterday. I just think as borderline as it was that it should have been declared a cane yesterday. I don't know why there was such a hold on saying that it was a hurricane, because I really think expectations would have met what we're seeing than to say it's just a tropical storm. I'm on the NS in Slidell and it is rocking out here, I can only imagine how much worse it is south of here. With the Lakefront experiencing the winds they have, the Westbank and N.O. have been getting their butts kicked.
