Do I need to active SEWS if it is required?

SEWS is automatically included for all hazards at Emergency Warning and Evacuation notifications (excluding Safe to Return). Unlike in OSOM Information and Warnings Officers (Duty Officers) do not need to choose if SEWS is required or what the frequency is. 

Cancellation of SEWS

Feedback from Emergency Broadcasters indicated that a cancellation of SEWS is not useful. There is no functionality in EM-COP to cancel SEWS. This change has been communicated to emergency broadcasters. 

Standard Emergency Warning Signal (SEWS)

SEWS is used to alert radio listeners and television viewers that an official emergency announcement is about to be made concerning an actual or impending emergency. You can hear the SEWS sound here
