Travel and Terrain Advice
Note the presence of unbonded storm slabs. Be careful of triggering on wind-affective ridgelines, where there are sudden changes in slope just below the branch ridge, and on steep slopes with few trees. Even more careful terrain selection is required at higher elevations where avalanches are likely to be larger due to higher snowfall. Remember, the best slope to ski is the avalanche terrain itself. Remember that the best slope to ski is the avalanche terrain itself. Remember the basics: one person at a time, moving from safe zone to safe zone, and those in the safe zone monitoring the skiers.
Avalanche Problem
ストームスラブ Storm slab
Be careful of triggering on steep slopes with few trees or where there is a sudden change in slope just below a ridge or a branch ridge.
概要
Avalanche
A human-triggered size 1 slab avalanche was reported yesterday on the southeast slope near the treeline, although visibility was poor.
Snowpack
New storm slabs are expected to form due to snowfall with winds shifting from south - west - north. On the southerly slopes, faceted snow was observed on top of the crust, which has been buried by this stormy weather and should be carefully watched for further bonding. Localized avalanches have been observed on this crust. Low surface density in areas with little wind influence, caution should be exercised in bonding with new snowfall.
Weather
As of 4:00 pm, 17 cm of snow had fallen in the past 24 hours at AMeDAS Fujiwara, and snow is still falling. The Japan Meteorological Agency is forecasting cloudy skies in the foothills of northern Gunma Prefecture with occasional sunshine before noon and snow or rain showers until morning as a low pressure system moves east of Japan and is gradually covered by a high-pressure system.
