What is an intense fear of snow called?

Chionophobia, or intense fear of snow, is a type of phobia categorized as an environmental phobia. Environmental phobias include other weather-related phobias like the fear of thunderstorms (Astraphobia) and the fear of wind (Ancraophobia). According to the American Meteorological Society, environmental phobias like Chionophobia are the second most prevalent phobia subtype.

Chionophobia is not just a dislike of snow or a rational fear of severe weather forecasts. It is an irrational fear of snow that is typically linked to a fear of death or bodily harm. Though phobias can and do manifest themselves differently in different people's experiences, there are typically two primary fears behind Chionophobia: The fear of becoming snowbound and the fear of being stranded in snow.

Like all phobias, the fear of snow may cause a variety of symptoms. Paying undue attention to weather reports, refusing to leave home during snowy weather, and experiencing panic attacks are extremely common in people with Chionophobia.
