🔹 The system is designed to save lives by sending urgent safety advice during major emergencies, such as severe weather, fires, or public safety incidents.
🔹 It was first used during Storm Darragh in December last year, when around 3 million people in Wales and south-west England received a red weather warning alert for life-threatening conditions.
What you need to know:
👉 Phones will make a loud siren-like sound for about 10 seconds.
👉 It’s a test — you don’t need to do anything.
👉 The alert will sound even if your phone is on silent or vibrate.
👉 In a real emergency, follow the instructions in the alert.
‼️ Important for domestic abuse victims:
⚠️ If you have a hidden or emergency phone, please be aware that the alert will still make a noise even if the phone is on silent. To keep your phone hidden, switch it off or put it on airplane mode.
