Compare the 24-hour total with the wind line first. The headline number only helps once you know whether a cold storm crossing the Hakuba ridgeline is the pattern to watch. With a 740 to 1200 metre elevation band and 460 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 11 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is midday warming, which decides how long the first good surface lasts. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase a settled cold morning after the storm; skip a windy day where the surface never gets a chance to reset.
