Not good news as we are waiting to see how the storm is doing but the plane apparently is climbing as it may have technnical problems .

Looks like Recon is bugging out and going home early...

What a mess this thing has turned out to be! LOL


I understand what you're trying to say - that's why Ernesto is Isaac's brother. They suffered from the same problems - poor internal structures. Still quite impressive on satellite imagery, though. Don't give up on Isaac, yet, Ernesto wasn't doing well in the eastern Caribbean, but he managed to become an 85 mph hurricane towards the end. :)

Not an official forecast - just an opinion.

Could be an illusion, but looks like it's rotating WSW.
More importantly it looks to me that Isaac is getting even less organized and weaker, if that's possible. He is one pitiful tropical storm wannabee at this point. He's plenty big but what a mess! Not going to be a hurricane in my opinion before Haiti and any significant strengthening after clearing land would be a big surprise at this point. I think wxman57 said the same thing yesterday.

The Gulf of Mexico is quite warm with the Loop Current. If conditions are right, yes. Also, if Isaac went between Cuba and Yucatan Peninsula where the water is warm and has deep layers of warm water compared to the Gulf of Mexico.

personally, i think if it does head into the gom and strikes the central gulf coast it has every possibility of rapid deepening.

Mighty shame there that recon looks like they are lifting out, we need all the help we can get with discovering what on earth is happening in the lower levels.

The plane is ascending and heading back to base, presumably after some type of technical difficulty (either that or they only planned two center passes, which is possible because they took off from Florida... a long flight home!)

Do you have a reference for this similarity? I find:

GILBERT

TS - Sept 9
Cat 1 - Sept 10
Cat 3 - Sept 11
Cat 5 - Sept 13

yea, i see little in common with gilbert, yet i find frederick somewhat interesting. at some point isaac will get a central core going and if it does it over the se GOM a cat4 isnt unrealistic.

Gilbert was a very large storm. In fact the radius of outer closed isobar was quite large. Up to 555 nautical miles before it intensified! :eek:

Nothing is out of the question for sure, that would be interesting. But it is safe to assume that land interraction is on the likely side, which hinders or weakens.. don't see how it would have enough time to get up to THAT strength, especially given the fact it is barely hanging on as it is right now. Maybe a weak cat 3 I assumed.

Well yes she was strong upon entering the GoM then what Isaac is however Katrina went from a strong Tropical storm after crossing Florida to a Cat 5 in the GoM and we ALL know the kind of Damage she did. I'm not saying that's going to happen here but Tropical Storms most certainly can go from Tropical Storm to Cat 5 Hurricanes in the GoM depending on conditions, speed, and all kinds of other factors!

IMO, this radar image is telling. First thing, this is evidence to me that Isaac remains poorly organized. It appears as tho the you have rain bands that are moving in different directions. You have what appears to be a fading CDO south of PR which is heading due west and other rain bands that are moving NW or NNW that appears to be initated due to outflow boundaries. You could also make the argument that there appears to be a vort max just south-southwest of PR if you watch carefully.
