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 sheltered from the wind without steep hazards above.
On Sunday, a strong storm enters Colorado, favoring the Central and Northern Mountains. If the forecast verifies and the system stays north, new snow will not be enough to increase the avalanche hazard.
