With less than a week to go, people across Wales are being reminded to expect the second-ever national Emergency Alert test in September.
The system is designed to help protect lives by delivering urgent safety advice directly to mobile phones during major emergencies.
Mobile phones connected to 4G and 5G networks will receive the alert at around 3pm on Sunday 7 September.
The drill follows the use of the system in Wales during Storm Darragh in December 2024, when a rare red weather warning was issued.
Around three million people across Wales and south‑west England received the message, which warned of dangerous and potentially life‑threatening conditions.
During the national test on 7 September, mobile phones will vibrate and emit a loud siren‑like sound for up to ten seconds. A test message will appear on screens, making it clear the alert is a drill.
Ahead of the test, the UK government is running a public information campaign to notify people it is taking place, including communications targeted at vulnerable groups such as victims of domestic abuse. The campaign has featured the first national information video in British Sign Language.
As well as making clear the test is just a drill, the message will point the public to GOV.UK/PREPARE, a one‑stop website offering practical advice about steps households can take to prepare for emergencies.
