Steep terrain at lower elevations are most likely to produce wet loose avalanches. Be cognizant of you location in the terrain as even a small wet avalanche could push you over a cliff or into a terrain trap.

- Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary
On Sunday, a few loose wet avalanches where observed at lower elevations on steep terrain. Avalanche control works near silver star resort produced several small (size 1) storm slabs and one persistent slab avalanche that failed on the deep layer from December. estimated to be down 50 to 70 cm deep.
On Saturday, a skier reportedly triggered a small persistent slab avalanche in the trees, running on a crust buried in mid December.
Snowpack Summary
15 to 20 cm of recent snow will begin to settle, become moist and as temperatures rise lose cohesion. Strong to moderate south west wind is forming new wind slabs on lee aspects in the alpine and at treeline. In specific areas that are protected from the wind, surface hoar has been located and found down up to 20 cm.
The mid to lower snowpack contains a few crust/facet layers including one buried in mid December, now 50 to 70 cm deep.

Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Avoid freshly wind-loaded terrain features.
