Like when it rains in cities. What determines it?
There are a number of things that can trigger random weather in places: - Tornadus - Thunderus - And some places just randomly have rain or sand for no particular reason (its always there). - Seasons: These vary with places. Example: Iccirus City is full of snow in the winter. - Trees also change colour and leaves fall in autumn is kind of a weather. - It also depends on the date. - And the Time.
