When the live forecast shows even 10 to 20 cm of fresh in a 24 hour window, that is usually all the lower basin needs to ski deep, because the slope is short and the trees refill fast. Wind is rarely the deciding factor here; most riding sits below the ridgelines, so storms can be chased even when the rest of the Hakuba Valley is reporting hold-downs. The variable is temperature at the base. If it climbs above zero with the storm, the lower glades go heavy and only the top bowl stays light. Cold and quiet on the forecast means a buried day; warm and quiet means stick to the upper chairs.
