Probably rainfall, just light rain where I am currently but expect to be under the heaviest part in around 2-3 hours. If I am reading the met office chart correctly up to 16mm/hour of rain. Probably nothing to be overly concerned with unless you are outside at the time.
What do the colours represent?
Rainfall intensity. The sharp borders are from discontinuities in the colour scale.

Density of precipitation methinks, red yellow green blue from high to low
Edit: actually that makes no sense. Maybe it’s height of rain cover with the above colours, and the black spots indicate density?
Shit, I actually don’t know.
Looks fearsome though
Edit2: Best I can find, but it’s not that parseable

Looks like a standard precipitation map to me. Goes purple->red->yellow–>green->blue
what are the dark spots though
Each colour has a scale too, dark green is heavier than light green
Oh yeah, I see darker spots in the yellow. Good spot, cheers
