Ok. Here is some more user feedback. đ
For most outdoor activities/sports where wind or weather in general is important (that's why you have the alert function, right?), it makes more sense to have a no rain or max rain alert.
My wild guess would be it's just a very small minority of people who would activate an alert and say "ok, i'll just go out hiking/kiting/flying/sailing/fishing when it rains at least 5mm for three hours." đ¤
Might be different though for farmers and the like.
