Read the freezing level before the snowfall total. When Sea of Japan storm flow is the pattern to watch, the live numbers usually matter most in the first lift window. With a 329 to 1280 metre elevation band and 951 metres of vertical, the trees and upper storm laps hold soft snow well after the open faces are worked. A seasonal baseline around 15 metres means the headline numbers can be real storm signals rather than background noise. The swing variable is whether the snow line stays below the 329 metre base through the storm. Use the access rules on the day as the limit, then let the wind and temperature decide how far to push it. Chase it when 15 to 25 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
