When an emergency occurs, members of the public who are impacted need to be alerted quickly and consistently, via as many different communications channels as possible. Emergency responder organisations, such as local police forces, the Environment Agency in England or the Met Office, currently operate a number of bespoke public warning systems. It is important to standardise the format of the alert messages so that they can be issued from different systems yet take advantage of any nationally available capabilities that might be available. There is also the potential to take advantage of other alert and communication systems.
