Primary Problem: New Snow
Bottom Line: New snow will create the main avalanche hazards this weekend. Avalanches could show a wide range of characteristics, from slabs of wind-drifted snow to wet-loose avalanches that run long distances. Where more snow falls, slab avalanches could break within or below the new snow, even where not drifted. Wet snow avalanches breaking deeper than the new snow are possible on slopes that have wet, unfrozen snow below the new snow, or where a lot of precipitation falls as rain on a wet and unsupportable snowpack. If you travel on or below steep slopes, carefully assess the new snow for signs of instability. Continuously reassess snow stability throughout the day, and as you move through different aspects and elevations.

The Last Word

We began our daily forecasts on December 7. 130 daily forecasts and 464 reported avalanches later, we wrapped up our daily forecasting season on April 14th. While avalanches remain a concern until the snow is in the rivers, read our SEASON SUMMARY to look back at the heart of the 2023-24 avalanche year.
