Avalanche danger is CONSIDERABLE today in wind loaded areas near and above treeline on NW-N-NE-E-SE aspects, 34 degrees and steeper. Near treeline and below treeline, avalanche danger is CONSIDERABLE on NW-N-NE aspects near and above 7,000' on slopes 32 degrees and steeper due to possible overloading of persistent weak layers near the base of the snowpack. In other areas, avalanche danger is MODERATE.
