Be aware of the possibility of wet snow-point generation avalanches from large south-facing steep slopes in the lower elevation zone that are susceptible to solar radiation, elevated temperatures, and rainfall, and Glide avalanche from open cracks or cliff-like slopes.

On the southerly slopes, crusts were formed due to yesterday's solar radiation. In addition, the omnidirectional snow surface melted at an altitude of at least 1300 m or less due to the influence of rising temperatures. Snowfall that began at midnight is expected to be about 5-10 cm above it. This snowfall started raining at least 900m or less. There is a possibility that snow cover has shifted and wind slabs are formed due to the influence of the wind from last night at high elevations.
