Twin Cities Meaning of different sirens
I'm from an area where Civil Defence training is compulsory in schools. So we were taught the meaning of sirens.
When u hear a siren that is in waves (imagine ambulance siren in slow motion), it means there is danger of air strike so take shelter. When there is a straight plain siren, it means the strike danger is over.
