This emoji goes beyond just bad weather to imply a tense atmosphere, as if "something big is about to happen." It's effective when used before an important presentation or when a conflict is escalating.

It can also symbolize immense power or anger, like Zeus from Greek mythology. That's why it often appears when discussing a powerful attack in a sports game or a scene where a dramatic conflict erupts in a drama. It can also be wittily used to mean "on the verge of exploding with anger."
