The UK has a Green, Yellow, Amber, and Red warning system. Apparently it applies to temperature, snow, rain, flooding, and winds.

I see them light up over the motorway, "Heavy rain - Amber warning".
So with the recent panic of it getting cold (in winter, who would have thought

), I thought, "That's it, I'm going to find out what constitutes Green, Yellow, Amber, and Red for temperature ". But I've no idea. Is Amber -5c to -8c for temperature? What's Red rain? 1" rainfall, 3" rainfall? How do I equate a colour to normal life?
Useless system.
Does the US have a similar useless system?
And heavy rain? Water must have different weight, lol
