Kernpunkte

Wind drifted snow may exist in steep alpine terrain on leeward slopes. Otherwise, a soggy snowpack will make encountering a wind slab unlikely today. Remain vigilant for both avalanche danger and early season hazards.

    Uncertainty remains for snow totals and wind effected terrain at the upper elevations, (9,000 feet and above). If traveling above treeline, do so with caution. Look for wind effected surfaces and monitor for instabilities within the snowpack, like large shooting cracks and recent avalanches. Up high, winds have been stronger blowing from the south and southeast, with snow as the favoring precipitation type. With yesterday's warming temperatures, it's possible, dryer snow has been buried beneath heavier snow. Feel for firm snow above soft snow to gain an idea of the snowpack structure.      

    Yesterday, rain was observed falling up to 8,500 feet. Snow levels may have lowered overnight, nevertheless, the added moisture has decreased the likelihood of wind slab development near and below treeline.

Avalanche Discussion

With freshly moistened snow surfaces, it's reasonable to think about a wet-loose snow problem. While not a problem at this time, it's something to have on the radar if traveling in steep terrain where snow surfaces are wet and penetrable.

Another consideration is surface crusts. These are likely to form, if they haven't already, and will add to the dynamic nature of the snowpack. Be prepared for challenging travel conditions. Tread lightly, and remember, “Slow is smooth, and smooth is fast.”
