Avalanche Summary

You can trigger a large avalanche on slopes where you find firm pillows of drifted snow. Avoid them on steep slopes below ridges and in gullies. You are unlikely to get any warning signs like cracking or collapsing before you trigger an avalanche. Multiple people could ride a slope before someone finds a weaker area of the slope and triggers a slide. You can find safer travel on low-angled slopes and in sheltered areas.

For visual impact, here's a montage of last week's large avalanches from around the state.

Above-freezing temperatures, sunny skies, and light winds mean the snow surface could become wet on sunny slopes. You can trigger a slide where you find wet, cohesionless snow on steep slopes. Avoid steep slopes if you're sinking up to your ankles in wet snow. Rollerballs and point-releases are indications the surface is becoming wet.
