the ULL is over the Yucatan; there is a very weak surface low south of Cuba, because the IR shows the clouds south of western Cuba moving north, and the visible shows low clouds south of western tip of Cuba moving southeast (look very closely, and speed up the visible loop)

the Atlantic system is somewhat far south, but because of this, it may escape any signifigant shear, and does appear to be getting better organized
