Niseko Avalanche Information No.112
Saturday 28/03/2026 土曜日
山麓+2度降雪なし モイワ800m-0.8度南南東0.7m降雪なし アンヌプリ1100m-2.3度南西1.1m降雪なく薄い霧 ビレッジ1000m-1.6度南西1.5m ヒラフ花園-1.7度北2.3m小雨 花園800m+1.1度北北東6.4m 日本海弁慶岬南9m 神威岬東北東3m気圧1015hPa波高不明、
等圧線幅広く海上、山ともにおだやか、標高700m以上は小雨、午前10時以降は融雪が進む。鉱山の沢側壁標高1000m、モイワ見返り750mの亀裂が拡がっている。全層雪崩に注意、谷にいなければ事故に遭わない。4月に入ると鉱山の沢、アンヌプリ大沢標高1100m付近からの全層雪崩の危険が高まる。注意。立ち入り禁止区域春の滝、湯の沢、アンベツ谷、及び閉鎖されている水野の沢の全層雪崩の危険は雪解けまで続く。入ってはならない。特に湯の沢を麓へのお帰りルートとしてはならない。運悪く雪崩を食らえば春まで出られない。この情報はニセコのスキー場コース外の事故防止を目的に出されている。事故後に原因がわかっても死者は還らず何の意味もない。火事と同じで予防が一番とここでは考えている。毎度言いたくないが自然は失敗に手厳しい。各ゲートの開閉は山頂視界不良のため未定。パトロールの指示に従うこと。良い一日を。
Moiwa Base: +2°C, no new snow. Moiwa 800m: -0.8°C, SSE0.7m/s, no snowfall. Annupuri 1100m: -2.3°C, SW1.1m/s,no snowfall, light fog. Niseko Village 1000m: -1.6°C, SW1.5m/s. Hirafu Hanazono 1000m: -1.7°C,N2.3m/s. Hanazono 800m:+1.1°C, NNE6.4m/s. Coastal Data. Benkei Cape: S9m/s. Kamui Cape: ENE3m/s, 1015hPa, wave n/a.
The isobars are wide, and the sea and mountains are calm. Light rain above 700m and snowmelt will continue after 10am. Cracks are getting bigger on the Kozan no Sawa creek sidewall around 1000m and Moiwa Mikaeri at 750m. Be careful of full-depth avalanches; you won’t get caught if you stay out of the valley. In April, the risk of full-depth avalanches increases in the Kozan no Sawa and Annupuri Osawa around 1100m. Be careful. Also expect full-depth avalanches in the restricted areas of Harunotaki, Yunosawa, Anbetsu Valley and the closed Mizunosawa until the snow is gone. Never enter, in particular, do not use Yunosawa as a route back to the mountain base. If you are caught in one of these avalanches, its a death sentence. This information is issued to prevent accidents outside of the ski resort in Niseko. Even if the cause of an accident is known afterward, it is meaningless. The dead cannot be brought back. Just like fires, prevention is the best approach. I don’t like saying this everyday, but nature is a harsh mistress. Gate opening is undecided due to poor visibility at the peak. Please follow the patrols instructions. Have a good day.
