Travel and Terrain Advice
Pay attention to the storm slabs formed by yesterday's snowfall at high altitudes. It is important to look for convex and unsupported terrain that is easy to trigger, and choose routes and gliding lines that are skillfully avoided. On the other hand, where elevations are low, the temperature is forecast to rise today. Be aware of point-generated avalanches due to wet snow during the day on steep, southerly slopes that are heavily affected by solar radiation. In places where there is yesterday's fresh snow, there may be a pattern that occurs due to a decrease in its strength. Wet or wet snow is so heavy that it is easy to scoop underfoot. Think about whether there are any “terrain traps” below the terrain you are currently trying to act on. Have a nice day

概要
Avalanche
No the new avalanche were observed and reported yesterday (22nd).
Snowpack
Near the forest limit to the upper part there was a snowfall of 10-15 cm, accompanied by northerly winds, during the day yesterday (22nd). Where this fresh snow is at a low altitude, the snow became damp yesterday, and instability was in the direction of resolution. On the other hand, at high altitudes, the wind has now subsided, but it is well cooled due to the effects of cold, so it is necessary to pay attention to the behavior of the slab formed by yesterday's snowfall.
Weather
The Japan Meteorological Agency predicts southern wind, sunny, cloudy, late at night, snow or rain, and a high temperature of 10 degrees Celsius (elevation 418 m) for the northern part of Nagano prefecture. At the foot of Mt. Hakuba (elevation 703m), the temperature is -5.1℃ (as of 5:00).
