ニセコなだれ情報 第93号 Niseko Avalanche Info No.93

山麓6時-4度降雪なし、モイワ800m-6.5度東5.6m降雪なし、アンヌプリ1150m-8度風弱く降雪なし標高1000m積雪450cm、ヒラフ山頂-8度東風強く降雪なし、弁慶岬南南西6m/s、神威岬東北東4m/s気圧1031hPa波高0.9m、

 

標高1200m以上は東風が強まっている。気温は朝のうち低いが昼前にはプラス気温になる見込み。全体の雪崩リスクは低い。低気圧の接近で風が強まり気温も上昇の見込み。各山頂ゲートの開閉は未定、パトロールの判断に従うこと。

 

雪崩の危険を避けるため谷底の滑走を避けること。滑走後、斜面下にとどまらないこと。週末にかけて再び表層雪崩のリスクが高まる。降雪推移に注意 。雪は昨日ほど良くない。衝突や亀裂転落に注意。朝のゲレンデは良い。繰り返すが谷底を避けて滑ること。ビーコンやエアバッグを過信してはならない。季節は春に移行している。良い一日を。

 

Niseko base 6am: -4℃, no snowfall. Moiwa800m: -6.5℃, E5.6m/s, no snowfall. Annupuri1150m: -8℃, light breeze, no snowfall. 450cm snowpack at 1000m elevation. Hirafu peak: -8℃, moderate easterly wind, no snowfall. Benkei cape: SSW6m/s, Kamui cape: ENE4m/s, 1031hPa, 0.9m waves.

 

An easterly wind is picking up above 1200m elevation. The temperature is low this morning, but forecasted to rise above freezing level before noon. The general avalanche risk is low. Both wind and temperature is expected to rise as the next low-pressure approaches. Peak gates opening are undetermined, please follow the patrol’s decisions.

 

For minimizing the hazards, avoid the valley bottoms and do not stay still near the bottom of a slope after riding. The avalanche hazard will rise during the weekend. Watch the weather transition. The snow is not as good as yesterday. Beware of hitting trees or falling into cracks. The morning groomers conditions is very good. One more time, better not ski the valley bottoms and better not over-estimate beacons and airbags.

The mountain is slowly shifting to Spring. Have a nice day.
