Another warm storm with heavy rain is approaching.
Saturated snowpack will likely lead to wet avalanche activity on steep slopes.

No recent avalanches have been reported, but observations are very limited in this region.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Up to 10 cm of new snow can be found at upper elevations, which was redistributed by strong southerly winds into greater accumulations on lee slopes. This builds upon previous storm slabs, which currently overlie older layers and a thick melt-freeze crust down 50 to 60 cm.

At treeline, a crust is supportive to skis with moist/wet snow underneath. The new snow seems to be bonding well to the surface crust. At lower elevations, the crust is variably breakable.

Total snowpack depths range from around 80 to 150 cm deep at treeline, and diminish rapidly at lower elevations.

Tuesday Night
Cloudy. Rain expected early evening. 70 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level rising to 2500 m at night.

Wednesday
Cloudy. 50 to 80 mm of rain. 60 km/h southwest ridgetop wind. Treeline temperature +2 °C. Freezing level 2200 m.

Thursday
Mostly cloudy. 40 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1800 m.

Friday

Cloudy. 10 to 20 mm of precipitation as snow or rain. 60 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1800 m.

• Avalanche danger is expected to increase throughout the day.
• Keep in mind that the high density of wet avalanches can make them destructive.
• Be alert to conditions that change with aspect and elevation.
