Cool temperatures and no significant weather inputs are forecast for Wed.
Thursday skies clear, and on Friday, the freezing level climbs to 2600 m. The hazard will rise with snowpack warming, and reflect the highest danger for the day.
Large cornices are widespread, and failures have the potential to trigger deep slab avalanches.
No new avalanches observed or reported on Tuesday.
No cornice failures were noted; however, cornices are large and generally suspicious across the forecast region. See photo.
Sun crusts on solar aspects extend to ridgeline. Shady aspects hold dry, settled snow above 2300 m. Temperature crusts are forming below 2300 m, with isothermal snow at lower elevations. The March 20 rain crust is 10–50 cm deep and extends to 2100–2300 m or higher. The January 24 persistent weak layer (facets over crust) is down 70–160+ cm. Below this, the snowpack is generally strong with no significant weaknesses.
Wednesday: Mostly cloudy, light winds, and alpine highs -11°C.
Thursday: Mix of sun and cloud, clearing through the day. Light winds and alpine highs -8°C
Friday: Sunny with a few clouds, light wind, alpine highs -4°C, and freezing levels climb to 2600 m
