Wide variability and springtime conditions exist. Cornices are a prime concern for avalanche triggering. Solar radiation is expected to be strong today, so timing and route selection will be important.
Summary
Weather Forecast
Clear skies this morning giving way to overcast skies as a weak disturbance moves through late this afternoon. Winds may keep things cool, but direct solar radiation will cause locally very warm conditions. Another low pressure is expected for Thursday and Friday, with cool unsettled weather for the weekend.
Snowpack Summary
In the alpine, due north aspects are maintaining dry snow conditions over multiple temperature crusts. Solar aspects have more crusts, and daytime warming is creating sticky, wet, and/or crusty conditions. At lower elevations (below 2200m), the snowpack is largely isothermal, but overnight re-freezing provides firm travel early in the morning.
Avalanche Summary
The number of avalanche observations is dropping off, in part due to fewer people in the backcountry to report. Cornice failures remain the biggest concern for triggering larger slab avalanches, which are mostly failing on the April 3 PWL (sun crust-surface hoar combo), down 40-80cm. Moist avalanches will be almost certain today.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Friday
