Avalanche Activity

Our zones have seen 15-36″ of new snow in the last week (lowest amounts at the pass, highest in the Lutak zone). South winds have been howling out of the southeast. Periods of heavy Precipitation will continue Friday night and Sunday, with 1-3″ of additional SWE and snow levels rising to 2000ft Saturday, and up to 4000ft Sunday.

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.

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

All avalanche terrain should be avoided this weekend. This includes lower runout zones in valley bottoms.
