Avalanche conditions will deteriorate on Saturday as a wet storm brings rain to most elevations.

Confidence
Moderate
Avalanche Summary
No recent avalanche activity has been reported. At elevations with significant snow accumulation, natural storm slab avalanche activity can be expected. Loose wet avalanches are possible elsewhere.
If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.
Snowpack Summary
An already warm, wet upper snowpack is being soaked by rain at most elevations. On the highest peaks, heavy snowfall may be accumulating over a rain-moistened surface.
A significant melt freeze crust is found 45 to 60 cm deep. It was reported to be a failure plan during snow tests near Mont Steele on Wednesday.
The mid and lower snowpack is generally well settled.
Snow depths at treeline vary across the region. Currently, 140 cm is reported in Knuckles, 95 cm on the North Shore and 175 cm near Sky Pilot.

Terrain and Travel Advice
- Travel in alpine terrain is not recommended.
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
- Keep in mind that the high density of wet avalanches can make them destructive.
Problems
Loose Wet
A rain-soaked upper snowpack will be primed for rider-triggered loose wet avalanches in steep terrain at most elevations. It doesn't take a lot of heavy, wet snow to knock a rider of their feet, or worse.
