Avalanche Activity

No recent avalanche activity has been reported for this zone. Look for evidence of any fresh wind slab avalanches that may have occurred over the last few days, and avoid those aspects.

Weather

Saturday should be mostly cloudy with light winds. Sunday will bring light but increasing snowfall, becoming heavy overnight. Monday-Tuesday will feature two strong and wet storms bringing heavy accumulations and snow levels rising to near 3000ft. Total new precipitation amounts of 2-3" are likely by Wednesday.

Additional Information

If you get out riding, please send in an observation!

Do a rescue practice with your partners. Always carry a beacon, shovel, and probe, and KNOW HOW TO USE THEM. Come to our FREE backcountry skills workshop on January 10th (see flyer below).

Practice good risk management, which means only expose one person at a time to slopes 30 degrees and steeper, make group communication and unanimous decision making a priority, and choose your terrain wisely: eliminating unnecessary exposure and planning out your safe zones and escape routes.

Alerts

Human-triggered wind slab avalanches will be likely on isolated wind-loaded alpine slopes this weekend. Use extra caution to avoid these areas.
