A cooling trend is decreasing avalanche danger. Use caution in the high alpine where isolated problems remain.
Small wind slabs may linger at high elevations near mountain tops. Assess for the bond with underlying layers before entering high-consequence terrain.
Cornices are large and fragile at this time of year. Give them a wide berth when travelling on ridges and limit your travel beneath them.
1 to 5 cm of snow is forecast for Wednesday, which will fall onto wet snow that may freeze into a hard melt-freeze crust. Small, isolated wind slabs may linger on north aspects near mountain tops, particularly where they sit on a hard crust.
The remainder of the snowpack is strong with various thick melt-freeze crusts.
Daytime warming from the past few days produced many small wet loose avalanches.
Looking forward, the likelihood of triggering avalanches will decrease with incoming cooler weather. Use caution in high-elevation northerly terrain where lingering wind slabs may remain and where cornices are large and unpredictable.
