高圧帯の北側で上空は西風が強く午前2時を中心に20m/sの突風、降雪は5-10cmだが東側にふきだまりが発達、標高800mノールで最大60cm、朝のうちは刺激で破断しやすく午前中の雪崩リスクはやや高い。各ゲートは時間を遅らせて開けられる見込み。パトロールの指示に従うこと。標高700m以上は風成雪でリセットされているが底当たりする。暴走すれば転んで骨折するので慎重な滑走を。吹きだまりが堆積した谷の側壁では浅い表層雪崩に注意。この情報はスキー場とその周辺の雪崩事故防止のために出されている。ヨーロッパと北米では今年50人以上が雪崩で亡くなっている。ガイドやリーダーは学んだ知識を過信してはならない。知識が誤っていれば今後も事故は起こり続ける。このスポーツに安全はない。良い1日を。
Mountain base: -6°C, 7cm new snow, calm. Moiwa 800m -9.3°C, WNW 6.2m/s, 50cm snowdrift development. Annupuri 1100m: -11.9°C, W 6.6m/s. Niseko Village 1000m: -10.8°C, WSW 3.7m/s. Hirafu Hanazono 1000m: -11.5°C, N 1.7m/s. Hanazono 800m: -8.3°C, E 3.2m/s, 5cm new snow. Sea of Japan Benkei Cape NW 11m/s. Kamui Cape WSW 13m/s, 1023hPa, wave height 2.1m.
Westerly winds remain strong in high elevation, with gusts reaching 20m/s around 2:00 AM, as the northern edge of a high-pressure system is passing nearby. Although new snowfall is only 5-10cm, wind slabs have developed on eastern slopes, reaching up to 60cm on knolls at 800m. These slabs are prone to fracturing under stimulation this morning; the avalanche risk for the morning is relatively high. Gates are expected to open with a slight delay. Follow the instructions of the ski patrol. Areas above 700m have been reset by wind-blown snow, but you will still hit the firm bottom. Skiing out of control leads to falls and broken bones. Always ride within your limits. Be alert for shallow surface avalanches on gully sidewalls where snowdrifts have accumulated. This information is issued to prevent avalanche accidents within the resort and its surroundings. More than 50 people have died in avalanches in Europe and North America this year. Guides and leaders must not be overconfident in the knowledge they have acquired. If that knowledge is based on flawed assumptions, accidents will continue to happen. There is no such thing as absolute safety in this sport. Have a great day.
