In sintesi

Over the last week the snowpack saw rapid changes and will need time to adjust to the new load. Predominant southerly winds created wind slabs on W-NW-N-NE-E aspects near and above treeline. Triggering an avalanche remains likely on, below, or adjacent to ridgelines and convex slopes steeper than 30 degrees.  Look for the five red flags of avalanche danger at all times.

    Slopes west through east on the top half of the compass are most heavily wind loaded and it's safe to assume that the higher in elevation you travel, the more prevalent and monstrous these wind slabs will become. Giving areas where snow has drifted or been built into cornices a wide berth today would be prudent. These could be triggered by the weight of a single person. Recent avalanches, blowing snow, wind pillows and snow surface clues all indicate the presence of wind slabs.

    Direct evidence that cornices along ridgelines are reactive and could break beneath your feet if you find yourself near one.

 When the snowpack is in question, terrain is the answer...if you're not in avalanche terrain, you can't get caught in an avalanche! 

DEEP SNOW CONDITIONS: Yesterday, it was waist to chest deep above 7,000 feet. Tree wells are huge. Don't get casual day syndrome. Make sure your skills match the conditions. It's the real deal out there. Be prepared.
