ニセコなだれ情報 第37号 Niseko Avalanche Info No.37

山麓6時+3度雨、モイワ800m0度東7.8m/s降雪なし濃霧、アンヌプリ1150m-1度南東弱く濃霧降雪わずか、ヒラフ1250m-3度南東15m/s濃霧、日本海弁慶岬南8m/s、神威岬風弱く気圧989hPa波高0.5m、

 

低気圧による暖気流入、標高800m以上気団置換による濃霧、降雪はなく山麓は雨、標高1200m以上は南南東の風が強い。各山頂ゲートは閉じられる。

日中は雨やみぞれが続くがゲレンデの圧雪状態は良い。暴走転倒に注意。コース脇の新雪は重く湿って板をとられやすい。ゴーグルをふくタオルが必要。

 

コース外の状況は良くない。急斜面では深部層からの雪崩に注意。雪庇やスノーブリッジは崩壊しやすい。重いので危険。森の中の雪は難しいが面白い。立木衝突に注意。

低気圧通過後に風雪が強まり新たなふきだまりが発達する。1月9日層は今後の降雪下で雪崩発生面となる見込み。降雪推移に注意。

 

道路は滑りやすい。早めのブレーキと慎重な運転を。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。事故は悪天候の中でおこりやすい。良い一日を。

 

Niseko base 6.00am: +3°, rain. Moiwa 800m : 0°, E7.8, no new snow, thick fog. Annupuri 1150m: -1°, light SE winds, thick fog, trace new snow. Hirafu 1250m: -3°, SE15m/s, thick fog. Coastal data: Benkei Cape:S8m/s. Kamui Cape: calm, 989hPa, wave 0.5m.

 

The low pressure system is bringing warm air into the area. There is dense fog above 800m due to this air mass change. There is no new snow and rain is falling at the mountain base. Above 1200m a strong SSE wind is blowing. All peak gates will be closed.

The rain and sleet will continue through the day, however the groomed runs are in good condition. Take care picking up speed and crashing. Snow off the runs is heavy and wet, its easy to catch an edge. Take a towel to wipe your goggles.

 

Conditions out of bounds are not good. Be aware of avalanches propagating from deep layers on steep slopes. Snow bridges and cornices are heavy, dangerous and will collapse easily. Snow in the forest is fun though, but be careful of hitting a tree.

After the low pressure sytem passes through expect the wind and snow to increase with associated snowdrift development. The Jan 9th layer is expected to become an avalanche generation layer in the future snowpack. Pay attention to the snowfall transition.

 

The roads are slippery, drive carefully and break early. This information is issued to prevent ski resort user accidents. Accidents are more likely to happen in bad weather. Have a good day.
