Overnight freeze will create supportive crusts that may breakdown late in the day. The timing and extent depend on winds, sun, rain, and daytime heating. If the crust breaks down, be well away from avalanche terrain.

Summary

Weather Forecast

Wednesday night may bring 4 cm of snow and -4 C. Thursday will be a trace snow, high -3 C, and freezing level 2000 meters with some gusting 40km/hr winds. Friday will be cloudy with isolated flurries, trace of snow, and Alpine temperatures Low -5 C and High 0 C, with freezing level 2200 meters. Precipitation may be light rain at lower elevations.

Snowpack Summary

Below treeline the snowpack is trending isothermal in the afternoons depending on the overnight freeze. Higher elevations maintains the crust with on-going multiple melt-freeze cycles. On north facing alpine slopes up to 15cm of surface snow overlies previous old dry surfaces.

Confidence

Freezing levels are uncertain

Problems

Loose Wet

Daytime heating will destabilize the snowpack as the surface crust melts particularly in late afternoons depending on the degree of overnight freeze. Rain can accelerate this process.

Travel early before the heat of the day.Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.

Aspects: South, South West, West.
