Tornado warning noisemaker (5)

I believe the answer is:

siren

(Other definitions for siren that I've seen before include "Loud whistle or dangerous woman" , "Dangerously fascinating woman" , "Bewitching singer,part- woman, part-bird" , "Temptress; warning signal" , "Warning device - femme fatale" .)

I've seen this clue in The Washington Post.
