Travel and Terrain Advice
Note the presence of a new storm slab due to snowfall that began at midnight. It is necessary to pay attention to triggering in places where the slope changes sharply. We recommend that you act in a place with a loose slope in the forest belt. Be careful of “terrain traps” such as cliffs and deep rivers, which increase damage even if the scale of avalanches that occur is small. It is forecast that strong snowfall will continue in the future. Pay attention to changes due to snowfall and wind effects.

Snowpack
The new snowfall that has intensified since last night is expected to be 30-40 cm or more at high altitudes. Be careful about the coupling in this snowfall. Bonding in the middle layer of snow cover is good.
