I believe 99L has degraded in organization today....any spin that it had prior to reaching the islands has pretty much vanished and now its a wide open wave with convection a bit more disorganized. Im not so bullish on this becoming a TD anymore, but it still has a shot.
That being said, the diurnal max could push this over the edge as the environment now seems more conducive for development, so later tonight it might get over the hump....but for now it looks more disorganized.
Here we go again. I have spoken (well, written) too much today to go over the same thing all over again. Every night, the same CD with the same song.
LOL! This certainly IS getting to be an old tune...
Phil,
The problem is that this is not a "tune" but a opinion that 99L was not going to develop over the last few days, not that it would never develop. It's hard to weed out the many repetitive posts that never gave this system a chance. Sometimes the chat environment of the board can be quite misleading...

Shear Tendecy maps show increasing shear as it enters the Caribbean. That explains the convection racing away from the center. It'll probably gain convection during the diurnal maximum, but it maybe be blown away during the daytime hours tomorrow. The shear tendencies might change to decreasing shear, but right now shear doesn't seem so favorable for the system right now.

If you look that is because it is situated under an area of upper level high pressure. The problem isn't and hasn't been shear.. it is the low level convergence.

You've got it, southfloridawx. That's a great point. The shear is increasing ahead of it, but only from roughly 5 knots to 15 at the most, which is not that significant. The convection is racing to the west, but so is the center, i.e. so what!
The lower level convergence is the problem, as you've said, so we need to take a look at how it will improve or degrade in the next days. Let's see what we can dig up about future low level convergence trends.

Unless something drastically changes, it sure looks like a Mexico event to me.

Thanks. Sometimes it's almost impossible to follow it all...

Re: Invest 99L Entering Eastern Caribbean - Thread #5
Those models in my opinion need to be taken with caution until we get a well defined LLC with deep convection.

Well it better..cause I refuse to go to bed until I see some explosion!![]()
There you go IH. See that convection wrapping around the northwestern part of the LLC?

Let's watch that...

I wont be watching models until we have a defined low..models are guessing right now on position and strength..2 big factors on track...

Looks very unimpressive this evening. Still no LLC, just an open wave. Lowest pressure is well SSE of the convection.

Don't think this will happen with 99L, but I recall the people in this forum being absolute about Ernesto going into Mexico/Texas.

Re: Invest 99L Entering Eastern Caribbean - Thread #5
I think 99L will be doing better tomorrow, still under upper level high pressure and it will move farther away from South America. We'll probably see a blow up in convection to keep it going a bit tonight, then I think tomorrow is show time for this area.

Very bad example...
Ernesto was at least a storm. Maybe we should wait till we get a defined LLC and then look at the conditions ahead of it?

Agreed....I think all the convection firing is a bit decieving.....the northern convection is definitely not related to any LLC, as its racing westward.

Forgive me if I missed that 99L is a developed storm

Also how about the exact conditions ahead of Ernesto? Do they mimic what is now ahead of our wave?
*Edit*
For the correct invest....99L
