Avalanche Summary

Strong winds vary snow depths across slopes and terrain, and drifting is observed in unusual places. Avalanches in the drifted snow could break several feet deep if triggered where older, weak layers are closer to the surface. Slab margins, near exposed rocks, and steep rollovers are areas where the snowpack is thinner and likely trigger points. Consider an alternative route if you notice the snow surface getting stiffer or if the snow surface looks smooth and rounded. You can find safer travel options on low-angled slopes without steep hazards above. Reports of areas with buried surface hoar in protected below treeline slopes. Avoid steep slopes if you think there is a chance this fragile weak-layer looms below your feet.

On Sunday, a strong storm enters Colorado, favoring the Central and Northern Mountains. If the forecast verifies new snow and strong wind will increase the avalanche danger.
