It is a day when you can enjoy a tour to a deep position where it is usually difficult to approach. Generally, the risk of avalanches is low, but it is necessary to pay attention to slabs that remain locally in extreme terrain shapes and very steep slopes. If you are raising the elevation, please be vigilant of places where hard snow surfaces are exposed and cornice. As you lower the elevation, pay attention to point avalanches of wet snow during the day. Wet snow is heavy, so it's easy to scoop up your feet, even if it's small. If there is a “terrain trap” such as a cliff below the slope, it can be a serious ending. And try not to approach slopes with glide cracks. Have a nice day
Yesterday (9th), many point-generated wet snow avalanches of size 1 were observed on slopes that are strongly affected by low elevation solar radiation and temperature rise.
The southern side of the forest belt is entering the spring cycle of thaw freezing. Snow is still kept dry on the north side, which is higher than the upper below treeline. The wind is moderately southward during the day and northwest at night near the main ridge line, and since there is only a small amount of snow that can move, only wind slabs that have passed time remain locally.
The Japan Meteorological Agency predicts north wind, sunny weather, and a high of 11℃ (elevation 418m) for the northern part of Nagano prefecture. At the foot of Mt. Hakuba (elevation 703m), the temperature is -7.0℃ (as of 5:00), and there is no new snowfall in the past 36 hours.
