Start with overnight snowfall and wind direction. Here, cold inland air is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 1100 to 1600 metre elevation band and 500 metres of vertical, the sheltered trees make modest reloads feel deeper than the raw number. A seasonal baseline around 17 metres means the headline numbers can be real storm signals rather than background noise. The swing variable is wind: light flow lets the trees refill, while a hard blast strips the exposed entrances. With patrol boundaries in play, focus on how the inbounds snow will hold through the first half of the day. Chase it when 15 to 25 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
