Check the freezing level against the full vertical first. When Sea of Japan storm flow is the pattern to watch, the live numbers usually matter most in the first lift window. With a 700 to 1500 metre elevation band and 800 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 13 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. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when 15 to 25 cm lands overnight with light to moderate wind; if gusts climb, make it a sheltered-tree day.
