Llover a cántaros combines the idea of llover with a cántaros, which literally suggests that buckets of water fall from the sky. It is not understood word-for-word in real meaning: the image serves to show a very strong rain, with a lot of water and no pause. If only a little falls, this expression is not used. It is reserved for an intense downpour, like the one that forces you to run, open a large umbrella, or seek shelter.
