Start with the upper-mountain wind and cloud line. 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 760 to 1831 metre elevation band and 1071 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 11 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is whether the upper lift can run with enough visibility to make the top worth using. 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.
