    Windslab will continue to build over the next 48 hours in all open areas with moderate to strong west/north-west winds. Ice Climbers should be especially observant to wind loading patterns when choosing a venue for the day.

Weather Forecast

A series of pacific lows tracking inland will bring strong westerly winds and significant snowfall on Tuesday and Wednesday. Details here: Mountain Weather Forecast.

Snowpack Summary

The shallow snowpack areas will be faceting and loosing support underfoot though much of the forecast region due to the sustained cold temps. Windslabs and wind effect in exposed areas. Oct. and Nov. crusts preserved in the mid and lower snowpack; both seem have a good bond to the overlaying snow.

Avalanche Summary

No new avalanches observed or reported.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday
