Weather Forecast

Flurries are expected to continue on Thursday. The wind should become light to moderate from the south on Thursday as the weak ridge of high pressure moves into the region. High pressure should continue to build on Friday; however moderate gusty westerly winds and flurries are expected to bring another 5-10 cm by evening. The next Pacific system is forecast to move into the region by early Saturday afternoon. Southwest winds should build to strong combined with moderate to heavy snowfall by Saturday evening.

Avalanche Summary

No new avalanches reported from Tuesday due to poor visibility and travel conditions.

Snowpack Summary

The new storm snow is the greatest concern at this time. There has been 40-60 cm of storm snow in the valley since Monday. The freezing level went up to about 1000 metres early Wednesday morning. The weak facet layer that was buried on January 20th is now down about 80 cm and continues to produce easy shears in tests.
