It's been a wild ride of unusual avalanche conditions. The buried persistent weak layer (PWL) of faceted snow became damp during last weekend's heatwave, and the snow above it became wet. Now, the PWL has gained strength and hardness, and the snow above it is solidly refrozen with several ice crusts. The combination of this refrozen snow and the increased strength of the PWL makes the likelihood of triggering an avalanche on it low today.
