Degrees of Avalanche Danger ?
With plenty of new snow, heavy precipitation rates, and variable winds, all aspects are suspect for fresh storm slabs up to 80 cm thick. Natural and human-triggered avalanches will be likely. Slopes 30 degrees and steeper should be avoided until the new snow has time to settle. Be especially cautious in any wind loaded gullies or lee slopes. Sliding surfaces will be density interfaces within the new snow.
On open or sparsely treed slopes below treeline: rain-on-snow will weaken and stress previous snowpack, both wet slabs and point-release slides will pose a danger. Do not venture onto steep slopes until the wet snow has a chance to re-freeze.
