In my game I have some rather harsh storms that happen periodically called magistorms. If you are caught out in them chances are you are going to die. There are 6 crystals (earth fire wind water blah blah) that protect the major cities, and these crystals grow and periodically chip off, then those smaller shards are granted to heroes or whoever and they can go and start smaller towns. The crystals protect you from the storms. So short answer is yes, I do track weather, and my weather hurts... bad.
