    Recent 45cm storm snow, now <30, has melded into the windslab. Trigger spots are shallow snowpack locations which could initiate a deeper release. Windslabs present lee features. Evaluate local wind effect as directions have been variable.

    Explosives on Friday released some size 3's to ground. Midpack strength is bridging this layer but the potential exists for human triggering especially in shallow locations. Consequences would be severe. Natural activity has tapered off.
