Moderate snowfall and westerly winds are forming fresh slabs over firm surfaces near and above treeline. Avoid slopes that face northeast through east to southeast, where you find fresh drifts over 8 inches thick. Shooting cracks are sure signs of unstable snow. Avoid this avalanche problem by moving to a slope protected from the wind. Despite cooler overnight temperatures, below treeline slopes may see a weak freeze. Watch out for trapdoor conditions and Loose wet avalanches on steep slopes in low valleys, and adjust your travel plans if you encounter wet, unsupportable surface snow.
