You could trigger an avalanche on steep slope near and above treeeline where wind-drifted slabs rest above weak, collapsible snow layers. Small slides may trigger larger ones where the snowpack is less than 3 to 4 feet deep. Common trigger points are near slab margins like rock outcroppings, steep rollovers, and below ridges or cliffs. 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 below treeline, and 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.
