等圧線幅拡がり海上、山ともにおだやか、山は昨日の西風で雪庇ふきだまりが発達、衝撃試験で上部30cmは破断、それ以下は下部100cmまで圧密安定。全体の雪崩リスクは低い。各ゲートは開けられる見込み、パトロールの指示に従うこと。標高700m以上は森の中を含め風でリセットされている。立ち木衝突に注意。この情報はコース外の事故防止のために出されている。ニセコは滑走者の意思を尊重するが、同時にルールの遵守を求めている。雪崩は自然現象であり、そこに人がいなければ事故は起きない。立ち入り禁止区域には絶対に入らないこと。常習化を放置すれば必ず事故が起る。ビーコンは義務ではないがあれば仲間の命を救える。スイッチを入れておくこと。山には雪崩以外にも多くの危険が潜んでいる。過信せず他者に配慮した滑走を。天候急変に注意。良い一日を。

The isobaric spacing has widened, and both sea and mountain are calm. Due to yesterday’s west winds, cornices and wind slabs have developed on the mountain. Impact tests show that the upper 30cm fractured, while the layers below are consolidated and stable for at least another 100cm. The overall avalanche risk is low. Gates are expected to open; follow the ski patrol instructions. Areas above 700m, including within the trees, have been reset by the wind. Watch out for tree collisions. This information is issued to prevent accidents outside the resort boundaries. Niseko respects the freedom of every rider, but that freedom comes with the responsibility to follow the rules. Avalanches are a natural phenomenon; if no people are present, no accident occurs. Never enter strictly prohibited areas. If habitual violations are ignored, an accident will inevitably occur. Beacons are not mandatory, but having one can save your or your companion’s life. Keep it switched on. Many dangers besides avalanches lurk in the mountains. Do not be overconfident and ski with consideration for others. Stay alert for sudden weather changes. Have a great day.
