Re: Tropical Waves Between Lesser Antilles and West Africa
shear doesnt seem to be a problem presently, based on the fact that convection has initiated directly over the center and isnt being blown away...this might also imply that the SAL id loosening its grip on the wave as well. How do conditions look near the windwards/ leewards, east caribbean and west caribbean?

Re: Tropical Waves Between Lesser Antilles and West Africa
Wave looks to have 2 areas trying to close off, which should also hamper development.

Re: Tropical Waves Between Lesser Antilles and West Africa
The wave crossed over the 27 degree SST isobar which the visible loop is now supplying.

I made a resolution not to get prematurely excited by pre invest activity this year but this area does look interesting. I will check the visible loop manana.
