山麓+2度小雨　モイワ800m-1.0度西0.7m降雪なし　アンヌプリ1100m+0.3度西北西3.8m濃霧視界不良　ヒラフ花園+2.0度南南西6.5m濃霧　日本海弁慶岬西3.0m　神威岬風弱く気圧1001hPa波高0.6m、

等圧線幅の広い低気圧の中で標高700m以下は引き続き暖気流入。上空には弱い寒気が入り標高800m以上は濃霧。霧が晴れれば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。昨日の低気圧前面降雪による雪崩リスクはほぼない。氷河雪崩と同様、全層雪崩も時間を問わず突然起こる。気温上昇や融雪で吹きだまりの重量が減れば、せん断応力とせん断強度が均衡して突然の破断は起きない。しかし鉱山の沢や大沢の谷底の滑走は控えるべき。雪崩は予測できない。ロープをくぐらないこと。パトロールの目を盗み立ち入り禁止区域に入らないこと。今日も良い一日を。

Moutain base: +2℃, light rain. Moiwa 800m: -1.0℃, S0.7m/s, no snowfall. Annupuri1100m: +0.3℃, WNW3.8m/s, thick fog and poor visibility. Hirafu Hanazono: +2℃, SSW6.5m/s, thick fog. Coastal data: Benkei capeW3m/s, Kamui cape: calm, 1001hPa, 0.6m waves. 

Warm air is flowing in under 700m elevation as the low-pressure system passes, but the isobars are widely spaced. Cold air is present in higher elevation, resulting in a thick fog above 800m. Gates are scheduled to open if the fog clears, please follow the ski patrol’s instructions. Avalanche hazard from yesterday’s pre-low pressure snowfall is almost non-existent. However, glide avalanches, like ice avalanches, can occur anytime without a sign. Sudden slides shouldn’t happen if the new snowdrift’s weight is reduced with rain and temperature rise, and the balance between shear strength and stress is even. However, it is still highly recommended to stay away from the bottom (natural halfpipe) of the Kozan-no-Sawa and O-sawa (Backbowl and Annupuri bowl). Glide avalanches are unpredictable. Do not duck ropes and sneak into strictly off-limits areas behind the back of the ski patrollers. Have a nice day.
