Don't look now, but wave #2 behind it is starting to get it's act together...

If the center is at 12.5/59.6 the convection is racing away from the center. Not good news for 99L.

Evening Thoughts,
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.

^Tends to happen in this manner with disorganized systems in non-ideal conditions....Although conditions are a bit better now.

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.

Yes Ivanhater, the environment seems much more conducive for convective outbursts, so tonight should be fun.

that increasing shear is the OUTFLOW. It is not shear

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.

Some people say "Just one more level, just one more level, just one more level". Storm2kers say, "Just one more convection flare up, Just one more convection flare up, Just one more convection flare up!" Lol.

Ok thanks! :) I'm only 14 so I'm still new at this TC stuff. I'm glad you told me that the shear was outflow because I was starting to think this would be another wave that would die off.
