Heʻe heʻe ua (pronounced "hey-eh hey-eh oo-ah") which literally means "running rain." This phrase captures the idea of the loud rushing sound of thunder following a heavy downpour.
Other options include:
* ʻUluʻulu (pronounced "oo-loo-oo-loo"): This word describes the sound of something rolling or booming, which can be used to describe the sound of thunder.
* Kaʻiʻu (pronounced "kah-ee-oo"): This word literally translates to "lightning," but it can also be used to refer to the sound of thunder in some contexts.
Ultimately, the best way to describe thunder in Hawaiian depends on the specific context and how you want to capture the sound and feeling.
