Online alarm clock for 8:37 am
As you hand over responsibility for checking the Met Office ice warning, set the alarm for 8:37 am so the next person knows exactly when to look. That leaves a clear point for confirming any update before 9:00 am, rather than relying on a hurried verbal reminder during the changeover.
For an ice-warning handover, choose a tone that matches the consequences of missing it. A gentle sound may suit a quiet room where someone is already watching the screen; a more persistent tone makes sense amid morning conversation or preparation. Check the volume after setting it. If the page is no longer open or the computer goes to sleep, this alarm will not sound, so the warning handover could be missed; keep a separate alarm available when nobody will remain at the screen.
Once the warning has been passed across, keep anything before 8:37 am simple: water, tea, or a small breakfast that will not occupy both hands when the alert sounds. Leave cooking or a longer coffee break until after the Met Office update has been checked. In the early morning, that small pause helps the person taking over respond promptly and still settle into the rest of the hour.
Common questions
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 8:37 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
