Travel and Terrain Advice
Due to the massive snowfall, the higher elevations where bonding is difficult to advance are dangerous avalanche conditions. Be aware of the presence of storm slabs on open steep slopes where there are few trees to anchor the snowpack. Note the presence of large avalanche start zones overhead, even if you are on a low slope with many anchors, such as in a tree line. There are exposed "terrain traps" such as deep gullys, cliffs, rocks, and standing timber that can increase damage even if the size of the avalanche that occurs is small. Be careful of falling into gully holes. The Japan Meteorological Agency is forecasting snowfall during the day. Please be aware of changes in the amount of snowfall and wind effects in the coming days.

概要
Avalanche
Unknown, as there is no information about his entry into the mountain yesterday (28th).
Snowpack
The snowfall that began on the evening of the 26th is expected to gradually settle as more than 100 cm of snow from the stormy weather is on top of the old snow that has been settling. On south-facing slopes, crusts are forming on the boundary surface between the old snow and the new snow, so care should be taken in bonding the boundary surface.
Weather
As of 4:00 pm, 2 cm of snow had fallen in the past 6 hours at AMeDAS Fujiwara, and the temperature was -5.4°C. Around 1,300 m elevation, about 15 cm of snow had fallen in the past 12 hours. The Japan Meteorological Agency has forecast that the winter pressure pattern will loosen slightly, but due to the influence of a pressure trough and cold air, northern Gunma Prefecture will be sunny and cloudy, with snow in the afternoon.
