Points saillants

Above-freezing temperatures today could create wet loose avalanche conditions. Firm surface snow in the morning can quickly transition to wet, mushy snow. Watch for these changing snow conditions and plan to be off of and away from avalanche terrain as these conditions present themselves.

    Temperatures hovered just above freezing last night at many of our SNOTEL sites. A thin refreeze is possible this morning and a firm surface crust could quickly transition back to wet loose snow conditions today. Temperatures are expected to be well above freezing today creating a possibility of wet loose point release slides. A small amount of wet and loose snow with the right terrain configuration can create a much larger slide as the snow gathers momentum down the terrain. Snow in and around radiators like cliff bands or rocks can warm the snow quickly creating mushy wet loose snow. Rocky terrain on solar slopes is a common springtime trigger for wet loose problems. Stay vigilant in your normal backcountry protocols such as putting one person at a time on avalanche terrain to reduce your risk of exposure to the wet and loose snow conditions that are often present in the springtime. 

Avalanche Discussion

Yesterday we toured out of the Virginia Lakes basin and had a look at Dunderberg Peak. The surface snow at 8 am had a thin crust and was transitioning back from freeze to melt at the start of the day. A moderate southwest flow cooled the surface snow slightly and the intense solar radiation of the late April sunshine rapidly warmed the surface snow. Boot penetration was minimal at most times except when venturing closer to rocky snow-covered terrain. In and around the rocks we sank in up to boottop. Corn snow was present on our tour in the morning and by noon, the snow had become soft and mushy in many locations. Mono County road crews were present and had worked their snow removal equipment up to the subdivision by the end of the day on 4/18.
