Travel and Terrain Advice
Pay attention to the wind slabs that have formed locally on certain terrain. The influence of wind is very strong, and thin wind slabs may form right next to where the hard snow surface is exposed. Be wary of convex or isolated areas where snow cover tends to destabilize, or slabs forming very steep terrain. The condition of the snow surface is when hard snow surface and tight snow powder are mixed in the same terrain. When there is no light and it is difficult to recognize the snow surface condition, please be careful not to get stuck in the trap and fall. In the mountains, falls attract a variety of problems. The weather is clearly downhill. An action plan that takes that into account.

概要
Avalanche
No new avalanche observations were reported yesterday (3rd).
Snowpack
At high altitudes, a very strong west to southwest wind blew yesterday. However, since the movable snow cover has also decreased, the formation of wind slabs is isolated, localized within a certain terrain, rather than a wide leeward slope. And this strong wind has also subsided in the wee hours. Places at very low altitudes, where the effects of heat rise and solar radiation are very strong, are in spring conditions.
Weather
The Japan Meteorological Agency is forecasting northern Nagano prefecture's northern wind, sunny weather, and sometimes cloudy from the afternoon, and a maximum temperature of 8℃ (elevation 418m). At the foot of Mt. Hakuba (elevation 703m), there was a temperature of -5.5℃ (as of 5:00) and snowfall of 2 cm in the past 12 hours.
