Watch for and avoid firm-rounded drifts of snow on steep slopes. On Friday, these areas will be harder to identify as they may get hidden by new snow. You will most likely find these drifts where you are enticed by continuous snow below ridgelines and in gullies. Experiencing cracks and collapses in the snow warns you that you have found a dangerous snowpack of firm snow over weak, older snow. You can find safer riding on slopes sheltered from the wind or lower-angled slopes.
Light snowfall starts on Friday and becomes a powerful storm over the weekend, raising avalanche danger.
