Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Avalanche Problem 1: Wind slab
Small wind slabs may be found in steep terrain on a range of aspects at higher elevations.
A few natural size two wind slab avalanches were reported in the last week at higher elevations. Little additional activity is expected during this drought.
Observations are limited this time of year. Please consider filling out a MIN report if you do head out in the backcountry! 🙏
Surface conditions are a mix of surface hoar topping 10-20 cm of faceting storm snow in shaded, sheltered areas, sun crust on steep south and west-facing slopes, and wind effect in exposed terrain at treeline and above.
A crust with sugary facets beneath it can be found 10 to 20 cm above the ground.
Expect early-season conditions with a shallower-than-average snowpack. At treeline, depths are between 60-100 cm. Below treeline, this tapers quickly.
Clear with valley cloud remaining below 2000 m. Southwest or west alpine wind 20-30 km/h. Above freezing layer at 2500 m diminishing.
Sunny with cloudy periods. Northwest alpine wind 5 to 15 km/h. Treeline temperature -7 °C.
Becoming cloudy. South alpine wind 5 to 10 km/h/ Treeline temperature -9 °C.
Cloudy with isoalted flurries continuing from the overnight period. Minimal accumulations. South alpine wind 15-25 km/h. Treeline temperature -7°C.
More details can be found in the Mountain Weather Forecast.
- Uncertainty is due to the limited number of field observations.
- Confidence is due to a stable weather pattern; little change is expected for several days.
