Points saillants

As the day warms, wet snow will form on sunny slopes. Large wet loose avalanches should remain unlikely, but rollerballs, pinwheels, and shallow wet snow sluffs could occur on steep sunny slopes. Exercise caution if traveling in steep terrain where wet snow exists.

    Last night, the NE-E winds, slightly cooler temperatures, and mostly clear skies should have allowed some of yesterday's wet snow to refreeze. Today, the sun and warm weather will melt those refrozen surface crusts, forming a layer of wet snow. Some rollerballs, pinwheels, and small sluffs of loose wet snow could occur on steep sunny slopes, but good drainage developed during this and previous melt-freeze cycles should help limit the size of any wet snow avalanches.

    Small sluffs of wet snow might still knock a person off balance or alter an intended travel path. Use caution if traveling in places where small wet loose avalanches might push you into terrain traps such as rocks, trees, or over cliffs.

    Ski cuts triggered small, shallow, sluffs of wet loose snow on steep sunny slopes around Incline Lake Peak (Mt. Rose backcountry). While these remained small, they could still push someone into an obstacle like the trees in this photo.
