  Slab avalanches are very likely as the storm deposits thick, heavy snow in the area. You could easily trigger an avalanche, and natural avalanches are likely to occur as well. As snow falls through Saturday temperatures will warm, leaving us with an "upside down" snowpack. which leads to heightened avalanche concerns. This means that snow at the surface is thicker and heavier than the snow beneath it. The heavier snow forms a slab that could easily slide on the lighter snow beneath it. Strong winds will redistribute snow at upper elevations into thicker and more reactive slabs also. 

  Feel for a "punchy" snowpack as you step, where heavier snow overlies lighter snow. Watch for obvious clues such as cracking, collapsing, and recent avalanches. The incoming snow may tip the scale on avalanches very quickly, before you even have a chance to register the change.  All these factors taken into account, give avalanche terrain a wide berth on Saturday. You can still get out and play in lower-angle terrain away from large overhead avalanche paths.

  Warmer temperatures at lower elevations could lead to wet snow conditions. Rollerballs and small loose wet avalanches are likely to occur in the wet snow surface. When you start noticing small rollerballs running down a slope, this may be a precursor to wet loose avalanches. Stay off steep slopes when you notice rollerballs frequently rolling down a slope.
