  • ニセコ雪崩情報第102号 Niseko Avalanche Info No.102

    山麓-2度降雪なし凍結　モイワ800m-4.8度南1.8m降雪なし　アンヌプリ1100m-6.4度西4.0m　ヒラフ花園-5.9度南南西8.9m　日本海弁慶岬南3m　神威岬南9m気圧1011hPa波高0.9m、

    標高800m以上は寒気流入が続くが山麓は融雪が進む。降雪降雨なし。この情報はスキー場利用者のコース外での事故防止のために出されている。ニセコは過去の事故多発の経験から事故防止に取り組み、ニセコルールという規則を設けた上でコース外滑走を容認しているが、これは国が正式に認めたものではない。国は現状を追認しているに過ぎない。情報では最も事故の多い冬の表層雪崩の危険を気象データと観測をもとに毎日提供するとともに、想定される雪庇崩壊や立ち木衝突、視界不良時の迷子などの危険なども述べ、スキー場利用者の事故防止に役立つよう努めている。山に入る全ての人が当日の危険を正しく理解すれば事故は減らせる。各山頂ゲートは開けられる予定。パトロールの意見を聞き準備してゲートからコース外へと出ること。このスポーツに安全はないが体には良い。良い一日を。

    Moiwa Mountain base -2℃,no new snow, frozen. Moiwa 800m: -4.8℃, S1.8m/s, no new snow. Annupuri 1100m: -6.4℃, W4.0m/s. Hirafu Hanazono 1000m: -5.9℃,  SSW8.9m/s. Coastal data: Benkei Cape S3m/s, Kamui Cape S9m/s, 1011hPa, wave 0.9m. 

     No snowfall or rain. This information is issued to prevent accidents off piste for ski resort users. Due to frequent accidents in the past, “Niseko Rules” were established many years ago to govern a system that allows skiers to ski in out of bounds areas in an effort to reduce accidents. Although not officially recognized by the government, it approves of the current situation. This report provides information on daily weather data and observations, danger of surface avalanches, when accidents are most likely to occur, as well as explaining other possible dangers such as cornices collapsing, collisions with trees and getting lost in poor visibility. Education to prevent accidents. Accidents can be reduced if everyone heading into the mountains understands the dangers of the day. Peak gates are scheduled to be open today. Please listen to the patrol’s advice and prepare before exiting through the gates. There is no safety in this sport, but it is good for your mind and body. Have a nice day.

    山麓-2度時折突風降雪わずか　モイワ800m-4.7度北北西13.6m風強く飛雪の雪庇ふきだまり発達　見返り750m-5度北西2.1m視界良　アンヌプリ1100m-7.1度西北西6.3m雪庇ふきだまり発達　ヒラフ花園1000m-6.3度北北東10.7m飛雪吹きだまり雪庇発達　日本海弁慶岬北9m　神威岬北西8m気圧1004hPa波高1.9m、

    冬型の気圧配置で夜半から未明にかけて北西風による雪庇ふきだまりが発達、雪庇は少しの刺激で破断しやすい。降雪は少なく雪庇やふきだまりは飛雪によるもの。ゲレンデの雪は風に飛ばされている。風下側標高800m以上のふきだまりは午前中破断しやすい。この情報はスキー場利用者の事故防止のために出されている。事故は不注意から起こる。それぞれが用心すれば事故は防げる。安易にロープ外を滑らないこと。立ち入り禁止春の滝、湯の沢には絶対に入らないこと。全層雪崩の危険が高まっている。危険を避けるため大沢や鉱山の沢の谷底にいてはならない。斜面に出来た亀裂は深い。転落に注意。5m以上ある。ニセコはコース外滑走を容認する。同時に事故を心配している。雪庇やスノーブリッジの突然の崩落、沢の増水に用心。各ゲートは開けられる予定。パトロールの意見を聞き準備してコース外へでること。良い一日を。

    Moiwa Mountain base -2℃,trace new snow, intermittent gusts. Moiwa 800m: -4.7℃, NNW13.6m/s, strong winds, wind blown cornice development. Mikaeri 750m: -5℃, NW2.1m/s, good visibility. Annupuri 1100m: -7.1℃, WNW6.3m/s, cornice and snowdrift development. Hirafu Hanazono 1000m: -6.3℃,  NNE10.7m/s, wind blown snow, cornice and snowdrift development. Coastal data: Benkei Cape N9m/s, Kamui Cape NW8m/s, 1004hPa, wave 1.9m. 

    A typical winter pressure pattern, northwest winds from midnight to dawn caused snowdrift and cornice development. Cornices are breaking easily with little stimulation. Cornice and snowdrift development has been from drifting snow, not new snowfall. Snow on the slopes has been blown by the wind and drifts on the leeward slopes above 800m are breaking easily this morning. This information is issued to prevent accidents among ski resort users. Accidents occur due to carelessness. Accidents can be prevented if everyone is careful. Do not duck ropes to leave the ski area, use the gates. Never enter Strictly Off Limits areas Haruno Taki or Yunosawa. The risk of full-depth avalanches is increasing. To avoid danger, stay out of the bottom of Osawa and Kozan no Sawa. Cracks in the slopes are deep, up to 5m. Be careful not to fall in. Although Niseko allows out of bounds skiing, we are always concerned about accidents. Be careful of cornices and snow bridges suddenly collapsing. Also water in the creeks is rising. All gates are scheduled to open. Please listen to the patrol’s advice and prepare before going through the gates. Have a nice day.

    山麓+4度雨　モイワ800m+1.2度南南西6.4m濃霧視界不良雨　見返り750m0度南3.7m濃霧視界不良雨　アンヌプリ1100m-0.2度西南西13.2m4時突風20m/s視界不良　ヒラフ花園1000m+0.4度南17.9m4時半突風27m/s視界不良　日本海弁慶岬西16m 5時7m 神威岬南西18m気圧992hPa波高1.4m午前5時前線通過、

    午前5時にサハリンの低気圧から延びる前線が通過、風は南から西に回り標高700m以上は午前中強風が続く。700m以下の雨は午前9時には上がる。亀裂から入った雨水と融雪水が地表を流れて全層雪崩が起こりやすくなっている。モイワボウル、見返りボウル、バックボウルや大沢ボウル、東尾根全域の斜面途中や谷底にいてはならない。全層雪崩は亀裂から発生が予測できるが亀裂のない斜面でも起こる。突然起こる雪崩の破壊力は非常に大きいので注意。立ち入り禁止の春の滝や湯の沢でも全層雪崩が頻発し始めている。特にまだ落ちていない湯の沢アンヌプリ側の斜面は近日中に雪崩が起こる可能性が高い。これらの場所には絶対に入ってはならない。雨で体が濡れる。ウールアンダーを着ることを勧める。濡れても唯一体温を保つ。自然相手のこのスポーツは厳しい。良い一日を。

    Mountain base +4℃, rain. Moiwa 800m: +1℃, SSW6.4m/s, thick fog, poor visibility and raining. Mikaeri 750m: 0℃, S3.7m/s, thick fog, bad vis, rain. Annupuri 1100m: -0.2℃, WSW13.2m/s (20m/s gusts @ 4am), poor visibility. Hirafu Hanazono 1000m: +0.4℃, S17.9m/s (27m/s@4am), bad visibility. Coastal data: Benkei capeW16m/s (7m/s@5am), Kamui cape SW18m/s, 992hPa, 1.4m waves. The cold front passed at 5am.

    The cold front from the low-pressure system in Sakhalin passed around 5am and the wind shifted from south to west. Windy conditions will persist above 700m elevation throughout the morning. The rain below 700m is forecasted to stop around 9am. The rain and thaw running down to the ground through the glide cracks could trigger glide avalanches. Stay away from valley bottoms and don’t stay on the slopes of Moiwa bowl, Miakeri bowl, Backbowl, Osawa bowl and Higashi-One. Glide avalanches can occur in slopes with or without existing cracks and are extremely destructive. Glide avalanches are already happening in strictly off-limits Yu no Sawa and Haru no Taki area. It is highly likely that one will occur in Yu no Sawa’s Annupuri side slopes in the near future. Nobody must enter these slopes. Wool baselayers are recommended as they will keep you warm even when wet. Nature can be punishing sometimes and that is why it makes this sport very demanding. Have a nice day.

    山麓+2度降雪なし曇り　モイワ800m-2.2度南南東4.6m降雪なく曇り　見返り750m-2度東南東1.8m降雪なく曇り　アンヌプリ1100m-4.1度西南西6.4m降雪なく濃霧視界不良　ヒラフ花園1000m-3.7度南11.8m風強く降雪なし濃霧　日本海弁慶岬南南西4m　神威岬南17m気圧1003hPa波高1.6m、

    山麓は気温が上がり融雪が進むが標高700m以上は寒気流入が続き1000m以上は濃霧、ヒラフ側は南風が強くリフト運行調査中、ゲート開閉は未定、パトロールの指示に従うこと。コース外滑走は勿論、自己責任で行われる。しかしニセコではゲートの開閉を行い、可能な限りスキー場利用者の事故防止に努めている。全層雪崩の危険を避けるため谷底にいないこと。雪庇やノールを刺激して雪崩を起こさないこと。パトロールの目を盗み立ち入り禁止区域湯の沢を滑らないこと。次に事故が起これば常習者の責任が問われる。春は天気と雪質が変わりやすい。用心を。ビーコンはオンか? ショベルやプローブ、ショートロープはあるか? 登山や山岳滑走は素晴らしいスポーツだが常に危険が伴う。良い一日を。

    Mountain base +2℃, no snowfall, overcast. Moiwa 800m: -2,2℃, SSE4.6m/s, no snowfall, overcast. Mikaeri 750m: -2℃, ESE1.8m/s, no snowfall, overcast. Annupuri 1100m: -4.1m/s, WSW6.4m/s, no snowfall, thick fog poor visibility. Hirafu Hanazono 1000m: -3.7℃, S11.8m/s, strong wind, no snowfall, foggy. Coastal data: Benkei cape SSW4m/s, Kamui cape S17m/s, 1003hPa, 1.6m waves. 

    The temperature rose and snow is melting at the base, however cold air is flowing in above 700m and a thick fog lies above 1000m. Strong southerly wind is blowing in the Hirafu side and the chairlift operation is on standby. Gates opening is to be determined, please follow the ski patrol’s instructions. Of course, skiing out of bounds is at your own risk, however, in Niseko, gates will be shut/open from accidents prevention measures’ perspective. Stay away from the valley bottom to avoid being caught in glide avalanches. Do not stimulate cornices and knolls as they could trigger a slide. Do not sneak into strictly off-limits areas behind the back of the ski patrols. If an accident occurs in these areas again, the repeat offenders will be held liable. The weather and snow conditions change quickly in Spring time. Stay vigilant. Is your avalanche beacon switched on? Are you carrying a shovel, a probe and a short rope? Mountaineering and ski touring are wonderful sports, however everyone should be aware of the risk involved in them. Have a nice day.
