In sintesi

Avalanche danger will increase throughout the day as warming temperatures and sunshine destabilizes snow by the afternoon on steep slopes facing the sun. Natural and human triggered wet loose avalanches will be more likely around rock features that heat up surrounding snow surfaces. Plan your travels accordingly to seek cooler, shaded terrain before slopes facing the sun become unstable.

    Full solar radiation with completely clear skies and temperatures above freezing across all elevations bands will destabilize recent snow throughout the day. Wet avalanches will be possible by the afternoon as east facing slopes warm first followed by south then west. Small D1 avalanches will be likely while larger D2 will be possible if large amounts of snow push into terrain features or traps. Look for signs of natural wet loose, rollerballs, or pinwheels with snow surfaces transitioning to wet or moist as clear indications of increasing avalanche danger.

    Avalanches with wet characteristics that occured earlier this week that caught and carried a skier.

Avalanche Discussion

Cornice/Rock Falls: As temperatures increase be aware of the potential for natural cornices and rock falls. Limit exposure below large cornices and remember that cornices can break further back than expected on ridgelines. These larger triggers also have the slight potential to trigger a large avalanche on buried weak layers in isolated areas. This occurred yesterday in Jensen Canyon, where a hard slab avalanche (D2-R2) was triggered by rockfall.  This area experienced increased avalanche activity two weeks ago and during the large Valentine's Day storm.  Human triggered persistent slab avalanches remain very unlikely. 

A full cycle of wet loose avalanches from clear skies and warm temperatures did not occur yesterday. This means there are plenty of slopes facing the sun still ripe for wet loose avalanches with slightly warmer temperatures today. Managing this problem can be easy if you choose terrain where you don’t have to travel across steep southerly slopes with heightened avalanche potential by the afternoon. Assess the snow surfaces throughout your travels as dry snow will destabilize quicker than areas that developed a crust yesterday and last night. Small wind slabs less than 8 inches deep could be lingering in isolated areas from increased northwest wind last night. Areas above the forecast boundary of 10,500’ will be impacted by the wind the most if you plan to travel into the alpine.
