ニセコなだれ情報 第64号 Niseko Avalanche Info No.64

 

山麓6時-8度降雪12時間1cmおだやか、モイワ800m-10.9度西2.9m夜半ふきだまりやや発達降雪わずか、見返り林道圧雪、アンヌプリ1120積雪深230cm静穏、水野の沢-11.97度北西1.7m/s降雪12時間3cm山麓積雪深158cm、アメダス寿都-4.9度積雪深53cm、倶知安-7.6度積雪深164cm、日本海弁慶岬北6m/s、神威岬北北西6m/s気圧1012hPa波高0.7m、

 

気圧の傾きなく海上、山ともにおだやか、観察各データから表層20cm付近での浅い破断は確認されたものの、全体の雪崩リスクは低い。各山頂ゲートは朝から開けられる。パトロールの意見を聞き準備してコース外へ出ること。山はトラックに覆われている。滑走注意。新雪を求め立ち入り禁止区域に入ってはならない。気持ちはわかるが一人が入れば大勢がそれに続く。事故防止のためにニセコルールへの協力を。

 

事故は悪天候時に起こる。ゲートが閉じられている時は周辺の山も危険な状態になっている。近年ゲート閉鎖時の周辺の山での事故が多い。ツアーガイドやリーダーはゲストや仲間の安全に大きな責任を持つ。冬山の危険を軽視しないほうが良い。ガイドはバスガイドではない。道を知っていれば良いというものではない。天候急変に注意。

 

Mountain base 6am: -8℃, 1cm snowfall in 12h, calm morning. Moiwa800m: -10.9℃, W2.9m/s, moderate snowdrift development overnight with slight snowfall. Mikaeri CAT track has been groomed.

The isobars are spaced out and the weather is calm at the ocean and the mountains. According to observations, some shallow surface slab slides are still considerable, however the overall avalanche hazard level is low. All gates are scheduled to open from the morning. Listen to the ski patrol’s instructions and be well aware and prepared before stepping out of the gates. The mountain is tracked out, beware of bumps. Do not enter the strictly off-limits areas to find fresh tracks. One track under the rope would lead many others to follow it. Please conform to the Niseko Rules in order to prevent tragic accidents.

 

Most accidents occur during poor weather. When the resort gates are closed, the surrounding mountains are also in hazardous conditions. Many cases of accidents have been reported when resort gates are closed. Tour guides and group leaders are greatly responsible for their party’s safety, be sure not to underestimate the hazards of winter mountains.

Mountain guides are not bus guides, just knowing the way back does not qualify them as a good guide.

Beware of sudden weather changes and have a great day.
