On Sunday the 23rd of April at 3pm UK time, there will be a nationwide test of the UK's Emergency Alert service. This system is set up to provide alerts to people when there is an immediate risk to life.
The service can send alerts on a regional or national level, and is intended to be used for things like extreme weather events. For example, if the risk of flooding was substantial in a certain area, an alert could notify users and give them the opportunity to take precautions.
