Actually there is a circulation, but no convection.. however, my eyes may be tricking me or a low may be forming around 72W and 24N.. I see a circulation, we'll see what happens in the future.

Also, IF and this is a big if.. if the storm gets into the Western Carribean and under the anticyclone (shield), it may become a more serious threat.. but we'll have to see what happens, it's seems like that twist I see on the visible is moving southwest.. again, we'll see what happens later.
