Travel and Terrain Advice
Be aware of the presence of storm slabs at higher elevations where snowfall increases and on open, steep slopes with few trees. There are exposed "terrain traps" such as deep gullies, cliffs, rocks, and standing timber that can increase damage even if the size of the avalanche that occurs is small. At lower elevations, exposed bushes make running difficult. Be careful of falling into gully. The Japan Meteorological Agency is forecasting more snowfall. Please be aware of changes in the amount of snowfall and wind effects.

Beware of open steep slopes with few trees.
概要
Avalanche
No one entered the mountain yesterday (1st), so the status of the avalanche activity is unknown.
Snowpack
Due to the influence of solar radiation yesterday, the crust is expected to form on the snow surface on the south-facing slopes. Low-density snowfall has been observed in places that are less affected by solar radiation and at higher altitudes. Since a heavy snowfall from last night is on top of this, it is necessary to pay attention to the interface between new snow and old snow and the bonding inside the new snow.
Weather
As of 4:00 am, 31 cm of snow had fallen in the past 12 hours in the vicinity of Amedas Fujiwara, and it is still continuing. The Japan Meteorological Agency is forecasting cloudy skies and snow until dawn in northern Gunma Prefecture due to the continuing winter pressure pattern and the influence of a pressure trough and cold air.
