冬型の気圧配置で吹雪、吹雪のピークは午前2時でその後等圧線幅開き標高1000m付近では平均15m/sの風雪が継続、等圧線幅が狭まれば再び風雪が強まる。観測と降雪推移、各データの評価から吹きだまり(風成雪スラブ)は安定しながら堆積、雪崩リスクは下がり始めているが、風が落ちてスラブが圧密安定するまで刺激しないほうが良い。雪は素晴らしく良いがまだ足りない。コース脇の立ち木衝突に注意。木には勝てない。パトロールは怪我を心配している。ゲレンデは仕上がって来た。人が多いので安全な滑走を。このスポーツに安全はない。他に配慮して安全な滑走を。リフトの横入りはその人の品格が問われる。スキー場規則とニセコルールの尊重を。ゲートが開くまで今しばらく時間がかかる。パトロールの意見を聞くこと。今日は寒い。凍傷に注意。良い一日を。

A typical winter pressure pattern resulted in a blizzard which peaked at 2:00 AM, after which the isobars widened. Winds and snow continued, with an average wind speed of 15 m/s at 1000m. However if the isobars narrow again, expect wind and snow to strengthen. From observation, snowfall trends, and data, it appears that snowdrifts (wind-driven snow slabs) are stabilizing and the avalanche risk is beginning to decrease. However, we need to wait until the wind dies down and the slabs are able to consolidate and stabilise before disturbing them. The snow is excellent, but it is still thin. Be careful of hitting trees along the trails. You can’t beat trees. Patrol is worried about injuries. The slopes are starting to look good. There are a lot of people, so please ski safely. There is no safety in this sport. Please be considerate of others and ski safely. Cutting in line on the lifts calls into question your dignity. Please respect ski resort regulations and the Niseko Rules. It will be a while before the gates are able open. Please listen to the patrol’s advice. It’s cold today. Be careful of frostbite. Have a nice day.
