Travel and Terrain Advice
At lower elevations, high temperatures and rainfall have increased the risk of glide avalanches. Pass quickly under terrains with glide cracks and do not stop there. In addition, the snow surface layer is saturated with water, so wet loose snow avalanches are very heavy. Such avalanches can also occur in forests. When they are swept away and hit trees, the added weight of the snow can have serious consequences. Today, as yesterday, high temperatures are forecast again, so please pay attention to the snow conditions during the day. Weather conditions are forecast to improve during the day. If you choose the right elevation, time, and slope orientation, you should be able to enjoy some nice spring corn snow. Have a good day. Today marks the end of the avalanche bulletin for the Myoko mountain area for this season. Thank you to everyone who provided us with information.
Avalanche Problem
全層雪崩 Glide slab
Steep slopes with glide cracks are very unstable. Do not dwell under them.
点発生湿雪雪崩 Wet Loose snow
The surface layer of snowpack is saturated with water, a situation that can produce very heavy avalanches. Although small, they can easily scoot underfoot and can also occur in the forest.
概要
Avalanche
Several size 2 glide avalanches were observed yesterday (30th). In addition, wet loose snow avalanches of size 1-1.5 were also observed.
Snowpack
Due to the high daily temperatures and rainfall, the entire snowpack is well wetted and reduced in intensity at lower elevations. Glide cracks on cliff-like terrain are extremely unstable. Also, even at higher elevations, loose snow avalanches caused by wet snow occurred yesterday on very steep slopes due to the effects of solar radiation and high temperatures.
Weather
Today, the area will be affected by a pressure trough and moist air, but is expected to be gradually covered by high pressure. The Japan Meteorological Agency is forecasting westerly winds, rain, cloudy before noon, then sunny, with a daytime high of 14 °C (13 m elevation) for the Joetsu region of Niigata Prefecture. At Sasagamine, Myoko (elevation 1,310 m), the temperature is 6 °C (as of 4:45 a.m.).
