Wind slabs will form on Thursday in the alpine with increasing wind from the West.

Summary

Weather Forecast

Seasonal temperatures, mixes of sun and cloud for the next couple of days. The main input will be the wind increasing to strong from the west Thursday late morning. 

Snowpack Summary

Up to 30cm cm of light, dry new snow with minimal to no wind effect over the past 48-hours sits over a generally well settled and deep snowpack. In areas with less snow (< 150 cm), a dense mid-pack overlies a facetted base while deep snowpack areas (> 150 cm) have a strong, solid base.

Avalanche Summary

Small loose dry avalanches smaller than size 1 were observed in the Simpson slide paths today.

Confidence

Due to the number and quality of field observations on Wednesday
