The Storm have beaten the Warriors 42-20 to record their fifth straight victory in the annual fixture.
The reigning premiers are now fourth on the ladder, while the Warriors have dropped to ninth.
The visitors were undermanned and Warriors coach Nathan Brown handed debuts to teenagers Reece Walsh and Rocco Berry.
Walsh has only been with the club for a couple of weeks, having been released by the Brisbane Broncos.
"We could see Reece's talent there today and he is a very talented kid," Brown said.
