Regions: Little Yoho.

Despite the cold temps, be wary of solar aspects in the afternoon. There may be enough power in the sun to trigger some small avalanches out of steep terrain.

Weather Forecast

An arctic ridge over the area brings mostly clear, dry and cold conditions through the end of the week. There is a chance of light flurries along the divide but little accumulation is expected. Winds are forecasted to be light. A warming trend arrives towards the weekend.

Snowpack Summary

The upper pack consists of storm snow from earlier in the month that is starting to settle and bond. This overlies a well settled mid-pack. The previously reported weak layers within the mid-pack (Dec 15, Jan 6, and Jan 16 layers) are becoming stronger and only producing hard to no results with pit tests.

Avalanche Summary

No new avalanches were reported or observed in the past 48 hours.
