Indeed, and it's great to educate people- maybe via normal text messages. An emergency alert should be kept for just that- an immediate, serious emergency.
It strikes me that only those of us that live in the South West of the UK have heard this alert in earnest before, so most PPs won't understand its efficacy when used sparingly.
Storm Goretti was intense, and it came on terrifyingly fast. Half an hour before we got 100mph winds, it was still a moderately windy night, and my idiot teen was going "Why do I need to come home? It's not even that windy!" I was able to say "Come home NOW", they've sounded the emergency alert, THIS IS FUCKING SERIOUS!". Two hours after that our village was completely cut off by falling trees, as was the next village, tens of thousands were without power for about 3 days, thousands without water for longer, everywhere you went there were twisted masses of trees and power cables. Yet only one person was killed (and he was at home in his caravan), because everyone had got the alert and hardly anyone was out on the roads.
If we ever find ourselves in the same situation again, Idiot Teen will be all "Oh they just sound these alerts for anything, they're just overreacting, I'm staying out riding my bike" or similar 🙄
