Radar image on watch face help

[mpovolo]

Hi. I use the watch face on a Garmin Fenix 8. On the watch face I have the radar image that loads every 5 or 10 minutes. There are 5 bars around the radar image that change to blue when weather approaches. What do each of the bars signify? Sometimes only 1 is blue, then all the way to 5 but I don't understand what each bar signifies. Description says +60 or -60 forecast.

Help
Thanks

@mpovolo Here is the article and short description of the whole radar feature on Garmin devices.

Thanks so much. So if in the forecast bars the top left is the only one colored that means in 60 mins precipitation is coming. And if say the first two are only coloured than that means for the next 20 minutes.
Essentially it's the forecast over the next 60 minutes.

Do I have that right.

Thanks
