Travel and Terrain Advice
Massive snowfall makes action difficult. Be aware of the presence of storm slabs on open, steep slopes with few trees. 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 not to fall into gully. Be aware of large avalanche slopes that exist above you even at lower elevations. The weather service is forecasting more snowfall. Please be aware of the increased snowfall and changes in wind effects.
Avalanche Problem
ストームスラブ Storm slab
Beware of triggering on steep slopes. Be careful of avalanches from upper slopes even if you are at a lower slope.
概要
Avalanche
Numerous human-triggered loose snow avalanches size 1 and one slab avalanche size 1 were observed yesterday (4th) on a steep slope in a forested area. No observations at higher elevations.
Snowpack
In areas with high snow cover, the 200 cm or more of snowfall from this stormy weather is on top of crusts on the southerly slopes and on top of less dense snowfall on the northerly slopes. Attention should be paid to bonding on the boundary surfaces and inside the snowfall.
Weather
As of 4:00 pm, 36 cm of snow had fallen in the past 24 hours at AMeDAS Fujiwara, and strong snowfall is still continuing. The Japan Meteorological Agency is forecasting cloudy skies and occasional snow until early afternoon in the foothills of northern Gunma Prefecture due to the continuing winter pressure pattern and the influence of a pressure trough and cold air.
