Avalanche Forecast

No new avalanches were reported on Wednesday.

On Tuesday, sluffing from the intermittent solar input occurred in steep terrain. Continued evidence of a widespread cycle to size 2 from last weekend's storm was reported.

Natural avalanche activity can spike on solar slopes when the sun is out. Storm slabs may be reactive to human triggers, especially on leeward wind-loaded slopes.

Up to 65 cm of storm snow sits above a crust on all aspects except on high, north-facing alpine terrain. Moderate to strong southwest winds have redistributed storm snow into deeper pockets on lee slopes at ridgeline, forming wind slabs.

A layer of facets and surface hoar which formed in February have been found 80 to 140 cm down, and a layer of facets and surface hoar from late January can be found down to 120 to 180 cm. No recent notable test results have been seen on these layers.

Thursday Night

Cloudy with some clear periods and flurries up to 5 cm. 25 to 45 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level valley bottom.

Friday

Cloudy with sunny periods. 10 to 20 km/h southeast ridgetop wind. Treeline temperature -2 °C. Freezing level 1200 m.

Saturday

Cloudy with 5 to 20 cm of snow. 15 to 50 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Sunday

Cloudy with snow 5 to 10 cm. 15 to 40 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1300 m.

• Keep your guard up as storm slabs may remain sensitive to human triggering.
• Avoid lee and cross-loaded slopes in the alpine.
• Even brief periods of direct sun could produce natural avalanches.
