You could trigger a large avalanche where you find a shallow area of the slope. Common trigger spots exist near rock outcroppings, steep rollovers, and beneath ridges and cliffs. Avalanches on previously drifted slopes can break wider and deeper, producing a more dangerous slide. The most dangerous slopes are steeper than about 35 degrees, are northerly or easterly-facing, and have signs of previous wind drifting. Drifted snow often feels stiff or has a smooth, rounded lense-like appearance. 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.
