Heavy snow and strong winds created dangerous avalanche conditions over the weekend. Conditions are still dangerous. You can trigger avalanches on northerly and easterly-facing slopes at upper elevations where thick slabs rest over old, weak snow. Avalanches can break at the ground and will be difficult to escape. You can trigger avalanches from the bottom of slopes or from a distance. Shooting cracks and audible collapses are indications of dangerous snow conditions. Be cautious if you travel in avalanche terrain on Tuesday; look for slopes less than about 30 degrees without steep slopes above for safer travel.
