Rising temperatures + strong wind + new snow = excellent slab building conditions.
Be prepared for rising avalanche danger throughout the day tomorrow.
Strong to extreme winds alongside some snow on Sunday will likely initiate another natural avalanche cycle. Avoid exposing yourself to overhead hazard. Expect this problem to grow into Monday.
The natural avalanche cycle has slowed, but human triggering still remains likely especially in wind prone areas.
Over the past few days there were numerous large natural & artificially triggered avalanches running on storm snow interfaces. These ranged in size from 1.0 to 3.5 and some were running to valley bottom.
Up to 25cm of snow fell in the last 2 days. At lower elevations, this new snow sits on a thin temperature crust up to 1700m.
We've had a LOT of snow in the past week! About 150cm of snow has fallen with periods of strong to extreme southwesterly wind.
Areas sheltered from the wind at treeline and below have a layer of surface hoar buried around 120cm deep.
A vigorous series of storms are headed our way. Expect extreme winds in the next couple days, and a heavy, warm storm on Monday.
Tonight Mainly cloudy. Low -2°C. Winds SW 30-60km/hr. FZL (freezing level) 1500m.
