Poseidon generates violent, stormy weather when he realizes what the gods have done.

Poseidon  was considered the god of the sea, protector of all waters in Greek religion and mythology.

Poseidon was the supreme ruler of the seas; he was related to storms, earthquakes, and some other violent forces of nature. When angry, he could stir the sea to a fury. However, he could calm the raging waters with just a glance as well. His title Enosichthon (Earth-shaker), depicted his ability to cause earthquakes by striking the earth and mountains with his trident.
