An Avalanche Watch is in effect. Very dangerous avalanche conditions will develop overnight Saturday and last through Sunday. Travel in avalanche terrain is not recommended on Sunday.For Saturday, you can trigger an avalanche on steep slopes facing northerly and east that have wind-drifted snow. If you trigger an avalanche in drifted snow, it can break deeply into weaker snow and break wider than you anticipate. You can also trigger avalanches on steep slopes where you find more than about 12 inches of new snow that is bonding poorly to the old surface. Shooting cracks and audible collapses are signs of unstable snow, and are clues you should avoid steep slopes.
