Alpine: CONSIDERABLE
Treeline: MODERATE
Below Treeline: LOW
Travel Advisory: 10 to 20 cm of new snow has accumulated in the alpine above 2000m. Variable soft slabs up to 20 cm were easily trigered in lee and cross loaded SZs. Below 2000m the storm snow is unconsolidated and moist and was sluffing on steep slopes. Cornice tabs have grown and will become weak with daytime warming and solar radiation.
Avalanche Activity: Size 1-1.5 easily triggered soft slab avalanches were running from steep start zones on Thursday. Mild temperatures yesterday afternoon resulted in several loose natural avalanches up to size 2 on south aspects. Watch for further avalanche activity throughout today on sun exposed slopes.
Snowpack: A dense layer of about 50 centimeters is sitting over hard crusts and an otherwise well settled snowpack. Up to 20cm storm snow has been loaded onto lee slopes in the alpine. Daily warming and overnight cooling should continue to settle out the recent storm snow.
Weather: A Pacific high is pushing current weather out of its way today with a ridge starting to build this evening into Saturday. Tody will see lingering cloud with possible flurries. The freezing level will climb to about 1900m. Sunday will see increasing cloud that will signal the approach of a fast moving front expected on Monday.
