未明にかけて強い地吹雪、山麓もふきだまり発達、量はまだ少ない。観測と各データから上は北寄りの風強く雪庇ふきだまりが急激に発達、吹雪には強弱がありスラブ発達は一様ではない。試験からこのウィンドスラブは衝撃で弱線破断しやすい。評価から本日の雪崩リスクは高い。吹きだまりが80cmを越えたコース脇の急斜面は表層雪崩が起こりやすい。新雪を求めて安易にコース脇のロープをくぐってはならない。急な気温低下と雪不足でゲレンデ状態は悪い。木も石も藪も人も多い。衝突に注意。スキー場からのコース外滑走はまだ出来ない。私たちも困っているが皆さんも今しばらくの辛抱を。風が西寄りに変われば雪は増える。降雪推移に興味を持つことを勧める。このスポーツに100パーセントの安全はない。凍傷と路外転落に注意。良い一日を。

Heavy blizzard conditions and a little snow into the early hours brought some minor snowdrift development to the base of the mountain. Observations and data indicate a strong northerly wind with rapid cornice and snowdrift development higher on the mountain . Blizzard strength is fluctuating and slab development is not uniform. Tests indicate this wind slab is prone to fracture on weak layers from impact. The avalanche risk today is HIGH. Surface avalanches are likely to occur on steep slopes beside the trails where snowdrifts exceed 80cm. Do not thoughtlessly duck ropes beside the trails in search of fresh snow. The sudden drop in temperature and lack of snow have left the slopes in poor condition. There are many trees, rocks, bushes, and people. Be careful of collisions. Off-trail skiing from the ski resort is not yet possible. We are also having trouble, so please be patient for a while. If the wind shifts to the west, expect increased snowfall. Keep an eye on the snowfall trends. There is no 100% safety in this sport. Be careful of frostbite and slipping on the road. Have a nice day.
