Travel and Terrain Advice
Watch out for bonding wind slabs that have just formed on the steep slopes just below the ridge and branch ridges. Conditions are hazardous at higher elevations where snowfall and wind effects are strong. There are exposed "terrain traps" such as deep streams, cliffs, rocks, and standing timber that can increase damage even if the avalanche size is small. Care should also be taken to avoid falling into gully. Be aware of the possibility of glide avalanches from open cracks or cliff-like areas. Do not enter the lower part of such areas or pass through them quickly. The forecast is for a winter pressure pattern. Please be aware of increased snowfall and increased wind hazards in the future.

概要
Avalanche
No reports of new avalanches observed yesterday (17th)
Snowpack
Snowfall with strong winds since last night has formed a wind slab on the downwind ridge and just below the branch ridge, and is expected to be blown away in wind-sensitive areas. The boundary surface of this wind slab is expected to be crusted on the southerly slopes and in all directions below 1800m. There are no reports of significant vulnerability observed within the old snowpack. At lower elevations, the snowpack is expected to be wet and reduced in strength due to the cold nighttime temperatures.
Weather
As of 4:00, the temperature at Amedas Fujiwara is -0.3°C. There has been 3 cm of snowfall in the past 24 hours, with about 12 cm near 1300 m. The Japan Meteorological Agency is forecasting cloudy skies with occasional sunny skies until late afternoon and snow showers in some areas, as the pressure will gradually shift from high in the west to low in the east and the northern part of Gunma Prefecture will be affected by cold air.
