Red Flags Comments
Heavy dense snowfall overnight plus strong winds. Didn't see any natural activity but visibility was limited. At lower elevations the snowpack is saturated and very sensitive to weight (ECTP10, 6900', NE).

Increasing Danger
Problem #1 Comments
Strong winds and snowfall have created wind drifted snow on steep slopes. Had limited visibility today - did not observe natural activity but the heavy density of the new snow combined with a riders weight may be enough to trigger an avalanche on lee slopes.
Avalanche Problem #2

Wet Snow
Trend
Same
Problem #2 Comments
Lower elevations are saturated and unconsolidated. Stability tests showed new snow easily propagating.
