AVALANCHE DANGER
Since yesterday winds have not decreased much and continue blowing from the NW. Even though wind loaded slopes will be the most sensitive, any slope steeper than 30 degrees is capable of producing an avalanche. Today the snowpack is unstable, human triggered avalanches are probable, and the avalanche danger is rated CONSIDERABLE
