  Avoid avalanche terrain, and don't linger in runouts where avalanches could come from above. If you experience whumpfing collapses or see avalanches break into deeper layers, you will be dealing with unmanageable persistent slab conditions. See more below.

  New snow accumulation could exceed 2 feet. The terrain above 5,5000ft should receive mostly snow, but even there, it will be warm and heavy. Moderate to strong southwest winds will make avalanches even more likely on the leeward sides of ridges.

  Put a large buffer between where you travel and all slopes over 35 degrees.  Expect that avalanches could run well into runouts and valley bottoms. Heed the warning of any whumpfs or cracks that break into deeper weak layers

  It won't take much to awaken the avalanche dragons in our weak snowpack. The new snow will stress weak layers throughout the zone. We expect avalanches will run naturally on older January weak layers.

  Wet avalanches will be the most common type to encounter at low elevations. While many will be smaller, some could be large and dangerous. Use extra caution if you see avalanches gouging deep into the snowpack or wet slabs breaking on deeper weak layers.
