These set what a day is worth to you on the weather score, and how hard a danger rating and a zone's terrain class count on the avalanche list. Change them any time, and your zones read them the next time they load.
Storm days or clear days? This picks your starting values below.
What each thing is worth to you on an alpine zone. Treeline zones count cloud and wind at half, and below treeline less, because trees give shelter.
What the danger rating at a zone's band takes off its avalanche list. You can make these stricter than the defaults, never lighter, and a higher rating never counts less than a lower one. How both work.
What a zone's terrain class (ATES) takes off its avalanche list. Stricter than the defaults only, and a harder class never counts less than an easier one.
