Check the freezing level against the full vertical first. The headline number only helps once you know whether a cold storm crossing the Hakuba ridgeline is the pattern to watch. With a 814 to 1614 metre elevation band and 800 metres of vertical, the bigger vertical gives you room to move higher when the lower runs soften. A seasonal baseline around 12 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is the freezing level, because the top can stay cold while the lower runs turn heavy. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when the storm exits cold and calm; skip if the tail end turns wet or windy.
