Highlights

It’s possible to trigger an avalanche in steep, upper elevation, wind-affected terrain. Look for evidence of wind-loaded snow. If the sun comes out, watch for wet loose activity on steep south-facing slopes. Widespread crusts, frozen debris and receding snow at lower elevations are providing challenging riding conditions.

    Natural wet loose activity is unlikely today but not out of the question. Cool and cloudy weather yesterday kept the wet avalanche activity to a minimum. A similar forecast today may do the same. However, once that sun pops out, recent snow will shed on southerly aspects. Watch for changing surface conditions and rollerballs. Consider overhead hazard if traveling below steep southeast through southwest-facing slopes.

    Isolated wind slabs exist at upper elevations. Northwest winds have moved recent snow into slabs up to a foot thick in exposed, wind-affected areas. Approach steep wind-loaded terrain with caution. Look for pillows, stiff drifts, and shooting cracks. Slabs will most likely be small but slick bed surfaces will facilitate further runouts and faster-moving snow. Consider the consequences of getting knocked off your feet above cliffs or other no-fall zones.

    Steep northerly slopes above 9500 feet hold up to a foot of unconsolidated snow. This may settle out today but watch for sluffing on slick crusts in this terrain.

Avalanche Discussion

Unless you’re trying hard to find an avalanche, the biggest hazard out there might be challenging riding conditions. Adjust your movement and anticipate changing conditions to account for everything from soft conditions on shady aspects in the alpine to crusts, frozen debris, and a lower-elevation lack of snow that can easily sneak up on you as you exit the mountains.

Part of this research includes a specific survey to better understand how useful avalanche forecast information is for trip planning.
