Re: ATL: INVEST 92L
only problem is there is not much left to regenerate. That LLC is winding down with no convection to sustain it. But I guess you never know....most of the globals dont do much with it so far...
BTW- they took the floater off it..

Yeah, there actually is no LLC anymore. It's a wave. But if you look at the RGB or visible loops it has very strong curvature, i.e. vorticity is still present. Look at the 850 mb vorticity it still has on the CIMSS chart below. So all you need is low shear and a moist mid-level environment, which it's got, and it can start producing convection again quickly, which in turn can produce a new closed low. I expect convection to really blow up over this tomorrow. Not saying any more than that for now.

It was a very impressive system but conditions didn't allow for it to develop. But it sends an important message that things could be very active from West Africa to the Lesser Antilles later in the season and those who live in hurricane alley (Me included) must prepare for a loooong CV Season.

Re: ATL: INVEST 92L
I know that the NHC and everyone else isn't covering it anymore. I thought that was obvious (??) Every season many waves start to develop into a tropical depression and get an invest number and then get sheared and lose the invest and then come back again. Is everyone missing my point that the tropical wave is still there and moving into a favorable area for regeneration and some possible development north of Puerto Rico tomorrow? That's all I was saying.
I circled the very strong wave here:

It stays here until further notice as things could change as our friend ozonepete said. Also,as replies continue to be posted, is the main reason it remains here.

There are no timetables about moving a thread from active storms/invests forum to the archieves one. If members continue to have discussions about any post tropical or post invest deactivation threads,then there is no problem to maintain it here.

pretty impressive still considering the conditions.. lets see what happens as it approaches the lower shear. tomorrow.

If there is nothing before... then just ask

Re: ATL: INVEST 92L
whats left of the circulation is right on top of PR at the moment. No convection except to the north. Still sheared like a big dog....no globals show any regeneration but you never know I guess.....

Re: ATL: INVEST 92L
Yeah , Rock, you can see the low level swirl passing just north of Puerto Rico now. I'm less bullish on seeing this rejuvenate now because as you said, the models don't do anything with it as of now and I don't see any lower level convergence or upper divergence over the area. However Aric is right that it will enter a low shear zone tomorrow and it still has a lot of 850 mb vorticity with it. Can't hurt to watch it.

So it is going to behave as a solar flare would?

Re: ATL: INVEST 92L
Ha ha it just might actually. Convection could flare up over it tomorrow as it goes north of the DR and then there's a second zone of shear north of eastern Cuba that that might kill it again, although that shear is lower and diminishing. The fun of watching it now is just to see what happens tomorrow. Such a strong low-level area of vorticity should usually initiate convection when there's no shear overhead and the area is moist at mid-levels. So we would expect that to happen here. It is a classic case where we can learn something by observation. If the convection doesn't flare we will try to figure out why.

I really can't see how this will regenerate convection tomorrow despite more favorable upper-level winds. It's not generating any convection now near the center of the swirl at all. Shear has certainly done it's job in tearing away the rest of the convection to the northeast of the naked swirl that is trying to hang on.

I remember a certain invest like this that went to TD 10 in 2005 only to die and then regenerate into Katrina....point is we never know so we watch.....
