Start with overnight snowfall and wind direction. When a cold storm crossing the Hakuba ridgeline is the pattern to watch, the live numbers usually matter most in the first lift window. With a 750 to 1289 metre elevation band and 539 metres of vertical, the sheltered trees make modest reloads feel deeper than the raw number. A seasonal baseline around 11 metres means moderate-looking totals can still refresh the main lines quickly. 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 10 to 20 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
