ニセコなだれ情報 第98号 Niseko Avalanche Info No.98

 

山麓6時-2度降雪なし、モイワ800m-5度東2.6m/s降雪なし霧、アンヌプリ1150m-8度西南西15m/s視界不良降雪なし、ヒラフ山頂-10度風強く視界不良降雪なし、日本海弁慶岬南4m/s、神威岬南18m/s気圧1013hPa波高1.5m、

 

降雪はなく標高1100m以上は南西の強風と視界不良。朝のうち山は凍っているが昼前には暖気が入って緩む見込み。標高の低い南側崖斜面では亀裂が広がり各所で全層雪崩が起きている。今後標高の高い南の急斜面、雪庇斜面で全層雪崩が起きる可能性が高い。事故を避けるため安易に谷底を滑ってはならない。雪崩が谷を一掃する。

 

各ゲートの開閉は未定 。パトロールの支持に従うこと。今日は光線がないので斜面が見づらい。またスノーブリッジが崩れやすくなっている。増水した沢に転落して流されると非常に危険。森の中でも用心を。山は春が近い。しかしそれにしても雪が多い。良い一日を。

 

 

Niseko base 6am: -2℃, no snowfall. Moiwa800m: -5℃, E2.6m/s, no snowfall, foggy. Annupuri1150m: -8℃, WSW15m/s, low visibility, no snowfall. Hirafu peak: -10℃, strong wind, bad visibility, no snowfall. Benkei cape: S4m/s, Kamui cape S18m/s, 1013hPa, 1.5m waves.

 

Strong SW wind, poor visibility with no snowfall above 1100m elevation. The slopes are frozen this morning but will thaw as the warm airmass flows in during the day. Cracks are forming and many glide avalanches are occurring in low elevation south facing steep/cliff slopes. Glide avalanches are also expected to occur in south facing steep slopes and cornice slopes in higher elevation. Better stay away from valley bottoms in order to avoid being swept by avalanches.

 

Gates opening is undecided. Please respect the patrol’s decision. The light is weak & flat making the slope’s undulation difficult to notice. Snowbridges are also becoming weak. Falling into swelling creeks is very dangerous. Please remain vigilant in all areas including treeruns. The mountain is shifting to Spring, but still a huge amount of snow. Have a nice day.
