Ok tkanks that's good news for you in Barbados my friend , hope the same in Martinica and for us in Guadeloupe....
So i will check the conditions in St Lucia and Martinica, to see ity.f the some tstorms are really bring some convective activity...
i know someone who live in martinica
Ok glad to see that Aric Dunnn , it seems that given the sat ...Ste Lucia is experiencing a nice flare up right now and this is approaching Martinica too, but i'm very confident that the activity will be confined in a short perimeter, hope it verifies after all ..

Looking at 93L I think the shear actually seems to be relaxing some in the E. Caribbean. I'm noticing that the high clouds flow doesn't appear to be racing NE as it was earlier this evening....
Hmmm....could there be a slight negative shear tendency situation happening in the E Carib tonight? In that case it would allow 93L to organize even further.
and..if 93L can survive the high shear environment ahead of it...any chance it could make it through into some areas of more favorable upper-level winds further West?

Re: INVEST 93L: Near Windward Islands
Shear keeping this invest in check, but it doesn't look like it's gonna destroy the small stucture as quickly as some seem to think.

Re: INVEST 93L: Near Windward Islands
This one has no chance. Upper level shear only becomes worse further west across the Caribbean Sea. It's currently facing strong divergence from the upper low NE of the Leeward Islands, and there is hostile shear further west.

The shear is actually not as strong as some think either in my opinion. Hopefully ULL winds will pick up later tonight to put it out for good.

Conditions certainly not favorable in the very near future but I wouldn't turn my back on it

Out of the frying pan, and into the fire, shear wise, if that is correct.

May technically be a TD at this point, but it should be going downhill from here due to shear, so I'm guessing no upgrade, and deterioration back to an open wave soon. Doesn't have much deep convection left.
IMHO

The type of this ball of convection reminds me curiously ...Marylin in 1995 , the early stages of developpement...but Marylin was bigger and more much organized and it's another story, just my subjective feeling but it's the same structure for me ...these type of Barbadian system very very tiny sometimes but well concentrated with a warm heart, beautiful and usually they have a sort a strengh and often develop quicker than predicted, speed speed as speedy Gonzalez lol . Hopefully no Marylin....that 's the good news of my story see you in the bed

Re: INVEST 93L: Near Windward Islands
The inflow out of the south was a hint that it could have a "LLC". Now theres west wind, but anyways it should not have much time.

Yeah what can we have more? 2 invest in a day in July 2nd? Anything else want an nexpresso?
It's amazing to have that right now in only the beginning ? Be serious, a TD would not occur but who knows, whereas a Td status seems pretty hard to believe , but as usual let's see what pans out....
