山麓-1度風よわく降雪わずか曇り モイワ800m北西316度2.8m/s-3.0度ふきだまりなし降雪わずか アンヌプリ1100m西267度3.0m/s-6.1度 湯の沢1000m南南西215度0.8m/s-5.6度 ビレッジ900m西南西256度1.0m/s-4.5度 ヒラフ1000m-5.2度 花園720m東北東70度-3.1度 日本海弁慶岬北西11m/s 神威岬西南西2m/s1008hPa波0.7m

 

弱い冬型の気圧配置で上空は西風やや強く寒気流入、標高700m以上ではクラスト上に3cmの新雪が積もり風下側は雪の量がやや多い。朝の観察、試験から全体の雪崩リスクは低い。各ゲートは準備が出来次第開けられる。側壁や標高1000m雪庇斜面からの全層雪崩の危険を避けるため谷底の滑走は控えたほうが良い。今年は総降雪が少なく例年に較べて全層雪崩のリスクは低いが、自然はわからない。常に用心するほうが良い。

 

山は雪も少ないが人も少なく滑るには良い。気温が上がれば標高700m以下は新雪がストップ雪になる。森の滑走は朝のうちが良い。立木衝突に注意。今日からモイワ山頂リフトが休止する。そのため見返り林道の雪崩調査も終了する。調査に協力してくれたモイワスキー場と圧雪車オペレーターに感謝する。良い一日を。

 

Mountain Base 6am: -1°, trace snow, light winds, cloudy. Moiwa 800m:NW 316deg 2.8m/s, -3.0°, trace new snow, no snowdrift development. Annupuri 1100m: W 267deg 3.0m/s, -6.1°. Yu no Sawa 1000m: SSW 215deg, 0.8m/s, -5.6°. Niseko Village 900m: WSW 256deg 1.0m/s, -4.5°. Hirafu 1000m : -5.2°. Hanazono 720m:ENE 70deg , -3.1°. Coastal data: Benkei Cape: NW 11m/s. Kamui Cape: WSW 2m/s, 1008hPa, wave 0.7m.

 

A weak winter type weather pattern is bringing cold air into the area and strong westerly wind at higher levels. Above 700m there is 3cm of new snow on top of a crust, leeward slopes have a bit more buildup. From observation and tests the general avalanche risk is low. Gates are expected to be open after preparations are made. Avoid getting taken out by a full depth avalanche by staying out of the valley bottoms. They are coming down from the sidewalls and cornice slopes around 1000m. The risk of full depth avalanches is less this year due to the below average snowfall, however we can never fully predict nature. Best to always be cautious.

 

Although there isn't lots of snow, there is no one around so the riding is good. As the temperature rises new snow below 700m will turn into “stop” snow. Morning will be the best time to ride in the trees. But be careful running into a one. Moiwa peak lift will be closed from today, therefore Mikaeri Avalanche Study will also conclude for the season. Thanks to Moiwa Ski Resort and groomer operators for your help. Have a good day.
