The Emergency Alerts system is used to warn if there’s a danger to life nearby, including extreme weather
Since the first national test of the system in April 2023, five alerts have been sent, including during major storms when lives were at risk. The government will be running a second national test on Sunday 7 September 2025 at 3pm
When it is tested (and used live time) it will send a loud, siren-like sound and a distinct vibration to all mobile phones, we just wanted to make you aware that this will be happening.
