There is a lot of conflicting activity going on at present, that cool bubble has pushed down over Belize as seen by that cloud dashed yellow line, where there are presently a few showers and down into the Pacific. The easterly Caribbean winds pushing against that cool bubble, and the high level westerly Pacific caused clashes and flare-ups over Yucatan last night and now in the Pacific.
