Chionophobia (from Greek chiōn, "snow") is the fear of snow. The cause of this phobia is commonly the result of a traumatic childhood experience involving snow, like getting injured while playing in the snow. For adults, this fear is often caused by traffic accident when driving through snow. Another, more physiological cause is looking at bright white snow causing eye pain. Chionophobia can even be developed from aquaphobia (fear of water), since snow is frozen water. It is considered a branch of pagophobia (fear of ice or frost) since snow is a form of ice.
