Travel and Terrain Advice
Climbers and skiers alike should be on the lookout for slip drops on icy slopes in the morning. During the day, be on the lookout for avalanches of wet snow on sunny slopes. Wet snow is very heavy and can easily trap your feet. If there are "terrain traps" lower down the slope, the consequences can be serious. At lower elevations, the snow has melted to the point where it is difficult to ski. Please be smart about the terrain in elevation zones where there is sufficient snow cover. The danger of glide avalanches continues and cracks have been reported at higher elevations. Keep a good distance from such slopes. Have a good day.
Avalanche Problem
点発生湿雪雪崩 Wet Loose snow
Note high daytime temperatures and sunny slopes. Rating is as of morning.
全層雪崩 Glide slab
Glide cracks are open even at the Treeline.
概要
Avalanche
Yesterday (March 28), a size 1 loose snow avalanche was reported in Alpine. In addition, several wet loose snow avalanches (size 1-1.5) and wet slab avalanches (size 2) were observed on slopes below 1,800 m elevation, possibly originating from the day before yesterday.
Snowpack
The mountains are changing to granular snow, except for some slopes on the north side of High Alpine. This is the "spring cycle" of freezing in the morning and then melting during the day. Glide cracks are also occurring below treeline elevations.
Weather
The Japan Meteorological Agency is forecasting northerly winds, clear skies, and a high of 15°C (418 m elevation) for northern Nagano Prefecture. At Amedas Hakuba (elevation 703 m), the temperature is -0.7°C (as of 5:00). Yesterday, at Amedas Hakuba, a maximum temperature of 10.9°C (at 12:00) was recorded.
