Moderate danger means that it is possible for humans to trigger avalanches in specific areas. Use caution in wind-affected terrain, where wind slabs may still be reactive.

Avalanche Summary
Avalanche activity quieted down on Sunday, with a few small (size 1) wind slabs in lee features at treeline and in the alpine from explosives. On Friday and Saturday, many small to large (size 1 to 2) slab avalanches within the storm snow were triggered naturally, by skiers, and with explosives. For examples, check out the MIN reports

Snowpack Summary
Around 20 to 30 cm of recent snow was redistributed from extreme south winds. Expect to find extensive wind effect in exposed terrain at all elevation bands. The snow may sit on a sun crust on south aspects, a temperature crust below 1700 m on all aspects, feathery surface hoar in sheltered and shaded areas, and sugary faceted snow elsewhere. The recent snow may not bond well to these layers.Below this, the snowpack is generally well-settled.
