Alpine Good とても急な斜面や南に面した場所で、点発生雪崩の痕跡を探してください。Look for tell-tale signs of point release activity in steep terrain and on Southerly aspects.
Treeline Good 滑るときも、登るときも、安全な行動様式を忘れないでください。少しの雪が動く雪崩でも、足元をすくうことを忘れないように。Remember to use safe travel techniques on the way down as much as the way up and be mindful of the consequence if you lose your feet even in a low-volume avalanche.
Below Treeline Good グライドクラックが降雪でやや隠れています。標高の低い地域で活動する方は、十分気をつけてください。Be wary of glide cracks that may now be slightly buried at lower elevations.

Travel and Terrain Advice
Don't get caught up in the “Summit Fever” that appears after a long period of no snowfall. This is because you should be able to enjoy the Notrak line every day considering the forecasted snowfall situation in the future. Before you run, you may want to think of a good line for yourself, but use that thought process to think about whether your current plan is reliable enough or if you need to make any changes Sai Remember that the cornice of the ridge is likely to be very unstable, and glide cracks are hidden by snowfall at lower elevations, which can have serious consequences. After a long period of dry conditions don't let summit fever grab you. Fresh lines will be available in the coming days as we receive daily top-ups of new snow. Have a clear idea in your head before getting on snow for what you think you are going to Find and use this process to build confidence in your plan or know when to turn around. Cornice May be brittle up high at ridgeline and low down glide cracks are ever-present and Could have high consequences.
Avalanche Problem
点発生乾雪雪崩 Dry Loose snow
降雪量が増えるにつれて点発生雪崩も、人の刺激で反応しやすくなります。数日の好天による日射によって形成した硬い雪面と、新たな降雪の結合ぐあいを確認してください。As new snow accumulation continues to grow loose snow activity may become reactive to single person loads in steep terrain. After numerous days of broken clouds and sunshine earlier in the week test the bond between the latest new snow falling on a temperature crust formed during that period.
概要
Avalanche
There are activity reports such as point avalanches in the past few days. Now new avalanche activity had been reported over the last few days.
Snowpack
Currently, there is a maximum of 50 cm of fresh snow near the forest limit, and it is forecast that snowfall will increase further in the next few days. Since the old snow layer below it is in a stable state as a whole, the focus is on how these old and new interfaces combine. Also, looking at the state of bonding with the thawing and frozen crust formed in good weather last week should be a good material for judging the situation. Currently, we have accumulated up to 50cm of new snow at treeline with more forecast during the coming days. Overall the snowpack remains stable with our focus is now on how the new and old snow interface will bond. The crust formed due to sunshine over the last week should be a key target for information Gathering.
Weather
A low pressure enveloped Hokkaido, and snowfall began throughout the region. Further snowfall is forecast for the weekend. Also, although the wind is closer to the west, it is expected to remain weak to moderate. As a low-pressure system wrapped around North of Hokkaido snowfall began to fall across the region at the end of this week. Further snowfall is forecast throughout the weekend. Winds will remain low to moderate from the West in the coming days.
