Avalanche Summary
No new observed.
Snowpack Summary
At treeline elevations (1200m) and above, 20-35cm of heavy snow from Thursday-Friday sits on the rain-soaked snow from last week's warmup. This new snow is bonding well to the previous rain-soaked snow surface. At alpine elevations fresh wind slabs could be touchy, especially if we do get as much snow as some forecasts suggest (up to 25cm by Sunday afternoon). The cooling trend early next week is expected to stabilize the snowpack - locking up the moist snow at treeline and below. The mid and lower snowpack are well settled and stable.
Problems
Storm Slabs
If you do encounter areas with >20 cm new snow, rein in your terrain use as storm slabs may also trigger deeper, weaker layers.
Minimize overhead exposure during periods of heavy loading from new snow, wind.Minimize exposure to overhead avalanche terrain, large avalanches may reach run out zones.
Aspects: All aspects.
