If you are only interested in disasters, I suppose, but even then: knowing that there's going to be a sports-related "riot" in local bars and venue-adjacent streets can be pretty critical information that is useful when it is timely. There are definitely cities where you need to know every time there is a local game and roughly what the mood of the crowd is, because crowd physics and mob mentalities. There are "sports-related disasters" in the weather of those cities.
