Travel and Terrain Advice
Sunny skies and warmer temperatures are expected during the day. Avalanche danger levels will vary widely from "low" to "high" throughout the day depending on temperature, solar radiation and rainfall. We recommend taking action before the crust loosens up. When the snowball begins to roll on steep slopes, it is a sign that the snowpack is losing strength. Watch out for loose snow avalanches. Be careful on large steep slopes as the size of the generated avalanche increases. Also be aware of the possibility of a block avalanche from a cliff-like area or a glide avalanche from an open glide crack. Avoid under such areas. Or move quickly.
Avalanche Problem
点発生湿雪雪崩 Wet Loose snow
Beware of large steep slopes
全層雪崩 Glide slab
Watch out for block collapses from cliff-like areas and open glide cracks.
概要
Avalanche
Numerous loose snow avalanche size 1-1.5 and one slab avalanche size 1.5 were observed yesterday on the steep slopes.
Snowpack
The surface to middle layers of the old snow are gradually gaining strength through the cycle of melting during the day and freezing at night. On top of this, 10 to 20 cm of snow from the stormy weather up to the 18th day of the month was deposited, and yesterday the settling progressed. Because of the rain at lower elevations, water is expected to percolate to the ground interface in areas where the snow cover is thin and glide cracks are open.
Weather
As of 4:00, there has been no precipitation in the past 24 hours at Ameda Fujiwara. Temperature -1.5℃. The JMA is forecasting clear skies and cloudy skies in the evening, with temperatures rising to 16°C at the foot of the mountains, due to the high pressure system, but subject to the effects of a pressure trough and moist air.
