For anyone in the UK who got the wildfires emergency alert but can't find it after hitting OK (to make it STOP etc), the GOV.UK English language version is at https://www.gov.uk/alerts/14-aug-2026-2 and both languages are belatedly at https://www.gov.uk/alerts/current-alerts (that originally only had Welsh for 15+ mins).

Android phone users may have history: Settings > Emergency Alerts > Alerts History. Apple apparently doesn't store them but have a play.

You can get RSS of the Emergency Alerts at https://www.gov.uk/alerts/feed.atom
