Kernpunkte

Continuing light snowfall and moderate to strong W-SW winds will maintain a slow steady increase in Avalanche Danger.  Lots of early season hazards to travel cautiously.  Getting much colder again by midweek - days are short and the nights are long.

    Watch for loose dry sluffing out of steeper terrain.� This will be important for Ice climbers to note as they are often in the pinch point of the hourglass where smaller sluffs can have big consequences.

Weather Forecast

An arctic air mass is sitting over most of the province.  A low pressure system developing along the arctic front will continue to produce light snow.  Westerly wind values will be in the moderate to strong range.  Colder arctic air will slip southwards dropping temps over the next 48 hours but light snowfalls and mod-strong winds will persist in our forecast area on Tuesday with temperatures dropping to -20 at least on Wednesday.

Avalanche Summary

Limited obs due to obscured conditions.

Snowpack Summary

Fresh new wind slabs forming along ridge crests and in gully features due to redistribution by wind action.
