    Rain has saturated the snowpack into the Alpine.  Expect this problem to be active as long as rain and above freezing conditions continue.

Weather Forecast

Wet warm conditions to continue through the weekend and then a cooling and drying trend into the week of Nov 14.

Snowpack Summary

Snowline has moved above tree line on southerly aspects and is rapidly disappearing on northerly tree line slopes. The treeline snowpack is saturated.  There is a melt freeze /rain crust that is present above 1800 m on north aspects and 2400 on south. Where snow is available for transport, thin windslab may have formed on this crust.

Avalanche Summary

Numerous loose wet avalanches to size 2 on steep North to Southeast slopes generally 100 m above treeline and stopping mid-path observed along the Parkway on Saturday.
