Travel and Terrain Advice
There may be a small dusting of fresh snow in spots but will be on top of icy snow underneath. This icy snow will cause for challenging conditions until the snow warms and softens. When the snow does warm and soften, travel with open eyes as to what the snow is doing around you as it warms. Wet loose avalanches can start small and far away, entrain snow as they move and become large. Travel tech tip: if you choose to travel with climbing skins, bring some wax to rub on the bottom of the skins to help the snow from sticking to the climbing skins.
Avalanche Problem
点発生湿雪雪崩 Wet Loose snow
The previous days rain has saturated the snow and as temperatures begin to rise and the sun comes out, the upper part of the snowpack will begin too warm.
面発生湿雪雪崩 Wet slab
The previous days rain has saturated the snowpack and if the snowpack warms too much with the sun and warm temperatures, wet slab avalanches will be a concern.
全層雪崩 Glide slab
Glide slab avalanches remain a concern with previous days rain and warm temperatures in the forecast.
概要
Avalanche
Before yesterdays rain, wet loose and glide slab avalanches were observed. As the sun comes out and the temperatures rise again there will be concern for avalanches.
Snowpack
The rain from yesterday put significant water and weight into the snow pack. The snowpack is frozen in most places from a cool night, but as the sun comes out and temperatures rise, the snowpack with become warm and wet again.
Weather
An easterly flow is sweeping across the zone bringing light to moderate east winds and temperatures warm at lower elevations. Expect partly cloudy conditions. Tonight the winds will move to come from the south and and bring clear sky and warm temperatures tomorrow.
