Travel and Terrain Advice
In the Alpine area, pay attention to poorly reactive wind slabs, which remain in an isolated form in the terrain local area. Be wary of wet snow avalanches on steep slopes at elevations lower than the forest limit. Also, set your route to avoid entering glide-cracked terrain as much as possible. It's going to be strong sunlight. Don't forget to wear equipment tailored to the spring cheerfulness, such as sunscreen and sunglasses. Have a nice day

概要
Avalanche
There were few visitors yesterday (24th), and there is no new avalanche observation information.
Snowpack
There is also the influence of cold weather, and in the Alpine there is a slight snowfall, which forms a slab due to the northwest winds. Pay attention to the instability that remains in the topographic area. On the other hand, at elevations below the forest limit, we are in a thaw and freeze cycle. Today, it is necessary to capture the state where the south wind enters, the snow on the snow surface gets wet and the strength decreases due to the effects of temperature rise and strong solar radiation.
Weather
The Japan Meteorological Agency predicts south wind, daytime, north wind, sunny, and high temperature of 16 degrees Celsius (elevation 13 m) for the Joetsu region of Niigata prefecture. At Myoko Sasagamine (elevation 1,310m), the temperature is -2℃ (as of 5:00), and there is no new snowfall.
