I'm writing a story about a paranormal tornado and the story starts at a basketball game,
but when the lights shut off and the warning sirens start, I don't know what sound effect
(onomatopoeia) to use.
Could you help me find something?

Assuming that the question is asking along the parameters that I believe it is, then "thunk," "clunk," and "clank" convey how much treble is in the sound, from least to most. "Thud" has also been suggested, which conveys a less abrupt cessation to the sound.
