Points saillants

Look out for isolated wind slabs in the upper elevations on terrain exposed to the wind today. Soft slabs could break 1-2 feet deep on steep wind loaded slopes capable of entraining large amounts of snow due to the underlying crust bed surface. More stable avalanche conditions exist in the middle and lower elevations where very small wet loose avalanches could knock you off your feet.

    Soft slabs 1-2 feet deep on steep wind loaded terrain features were reactive two days ago and are still possible to trigger in isolated locations including leeward ridgelines and confined features like couloirs or cliff features. Expect slab depths to increase the higher you climb in elevation. These wind slabs are trending more stubborn over time. Be aware that any avalanches triggered are capable of traveling far downslope on complex or sustained terrain due to the underlying crust bed surface. Obvious signs of shooting cracks may not be present as even slightly denser wind loaded snow could fail on the old snow interface.

    Small wet loose avalanches are possible on very steep slopes that receive direct sunlight. Watch for recent snow to destabilize quicker around rock features that heat up surrounding snow surfaces. Wet loose avalanches can start out small and entrain large amounts of snow on larger, sustained slopes. Pay attention to recent snow becoming denser and wetter as the day progresses and monitor cloud cover.

Avalanche Discussion

Stability Trends

Observations yesterday found more stable conditions than previous days as the new to old snow interface improves over time. The recent snow started to settle over the last 24 hours. Previously formed wind slabs are becoming less reactive, but still possible to trigger. Be more weary of wind slabs if you travel into more complex terrain. Lingering wind slabs will be more likely in alpine terrain exposed to the wind. 

Wet loose avalanches were reported primarily on very steep terrain around rock or cliff features yesterday. Expect similar avalanche activity today, with larger avalanches on larger slopes. Cloud cover is forecasted to increase throughout the day. If skies remain clear, be prepared for a higher likelihood of encountering wet loose avalanches as the snow transitions from dry to wet. The sun is strong in April and doesn't take long to affect snow surfaces. 

If you see avalanche activity today, please consider submitting an observation HERE. Observations allow everyone to gain a better and more complete understanding of conditions. Thanks!
