You can trigger a dangerous avalanche on many slopes where several feet of recent snow has overwhelmed a weak snowpack below. The thick storm snow may feel supportive and offer few instability signs before releasing a destructive slide. Don't trust any steep terrain that faces north-of-west, through north, to southeast. Slopes facing these directions hold buried weak layers that have not adjusted to the huge recent loads. Recent drifting from westerly winds continues to aggravate these concerns. Choose safer options in lower-angled wind-sheltered terrain not exposed to steep slopes overhead.
