Look at the most recent 12 hours, not the weekly total. When west to northwest flow off the Sea of Japan is the pattern to watch, the live numbers usually matter most in the first lift window. With a 530 to 700 metre elevation band and 170 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 10 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is timing, because the compact footprint gets tracked or softened quickly. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase a cold morning immediately after fresh snow; skip warm afternoons unless you are there for relaxed laps.
