Travel and Terrain Advice
Note the joining of the new windslab on the ridge at the high elevation, on the steep slope just below the support ridge. It is a forecast that there will be sunny days. Be aware of the possibility of wet and snow-generated avalanches from large south-facing steep slopes in the lower elevation zone susceptible to solar radiation and elevated temperatures, or Glide avalanche from open cracks or cliff-like slopes.

概要
Avalanche
Yesterday, there was a report that a Glide avalanche was observed on a steep slope closer to the south, but the details are unknown
Snowpack
On the southerly slopes, crusts were formed due to one-day solar radiation. In addition, the omnidirectional snow surface melted at an altitude of at least 1300 m or less due to the influence of rising temperatures. The snowfall until yesterday is about 5-10 cm above it. At a high altitude, due to the influence of the wind, the snow cover moves and the wind slab is formed.
Weather
The temperature at AMeDAS Fujiwara as of 4:00 a.m. -2.9℃. According to the Japan Meteorological Agency's announcement at 17:00 on the 2nd, it will be covered by high pressure, but due to the effects of barometric troughs and chills, the northern part of Gunma prefecture is forecast to be cloudy and sunny and snowy from late afternoon to early evening.
