A potent storm with strong westerly winds and heavy snow will result in very dangerous avalanche conditions on north through east-facing above treeline slopes. The strong winds will build thick slabs over collapsible weak layers near the ground. Avoid traveling on or under these slopes. Be careful around, and consider avoiding, any north through east-facing slope where there is drifted snow or storm totals exceed 12 inches.
