I'm having this problem right now, trying to plan some nice long walks out of the city but it's been raining a lot lately. I'd love some kind of map of flooding/muddy conditions, but I don't think it would be feasible without a massive effort (as whether an area is prone to flooding or turning into a mudbath after rain depends on a lot of factors).
