LOW avalanche danger persists at all elevations today. Generally safe avalanche conditions exist. Be on the lookout for isolated areas of unstable snow and be aware that the biggest hazards right now are the low coverage and variable surface conditions.

advisory discussion

Increased cloud cover may limit solar radiation today, and moderate to strong winds will act to cool down surface conditions as well.  Even still we may see surface snow soften by midday, particularly on solar aspects if the cloud cover proves to be less then expected.   Significant loose wet activity will remain unlikely. 

While our recent weather patterns have led to relatively benign avalanche conditions, the biggest hazards today may be the thin coverage and a variety of slick surface conditions. Field observations yesterday found very hard slick surfaces on all aspects. Slide for life conditions may exist in places you typically don’t expect to find them.  Terrain selection and timing will be important if you decide to venture into the backcountry today. It may be necessary to climb on hard slick snow and wait for the sun to soften things up before descending. Continue to practice safe travel techniques and bring the proper equipment for your objective.  Most importantly be flexible, and move to less consequential terrain if the challenging conditions don’t match up with your group's equipment or ability level.
