  Weak snow from January and early February is buried 2-4 feet deep. While it is becoming less likely that you will trigger an avalanche that fails on weak, faceted snow, keep your guard up above 8,500’ on northerly slopes and in steep rocky terrain. You might not get any warning signs, like collapsing, before triggering a large avalanche. Careful assessment of the snowpack is required before committing to steep terrain. 

  Keep an eye out for isolated wind slabs at upper elevations from increased overnight northerly winds. These will be small and shallow but might catch you off guard and easily knock you off your feet above hazardous terrain.

  Yesterday, snow surfaces below 8,500 feet were wet from warm temperatures and rain at low-elevations. Below 8,000 feet, many aspects contained isothermal snow. Overnight temperatures at 8,500 feet dipped below freezing as skies cleared, but it was not a hard freeze in some locations. Expect crusts to thaw quickly in the sun today. Wet snow avalanche activity is likely on very steep, low and mid-elevation slopes facing the sun and could entrain more snow than you expect. If you see rollerballs or encounter slushy snow, move to shadier aspects and minimize time spent under steep sunny slopes.
