warning siren
Loud danger signal
A warning siren is a loud, wailing alarm designed to alert a large area to imminent danger—tornados, air raids, tsunamis, or other emergencies.
The distinctive rising and falling tone carries over long distances and cuts through ambient noise: When the warning sirens went off, everyone headed for the basement.
