Just Cause 4 is coming in December, features scary weather

While I doubt anyone's surprised by the existence of Just Cause 4 at this point, given that two leaks have happened in the last week, we did just learn its release date during the Microsoft conference: 4th of December. In the footage, we see a few instances of exciting weather: first a tornado in the distance, and later a plane being pulled into one.
It otherwise looks like Just Cause as we know it: open world excitement, the wingsuit from Just Cause 3, lots of vehicle types and more.
