A cautious approach is still warranted where the snowpack is isothermal, especially if it's raining.

Summary

Weather Forecast

A cold front embedded in a SW flow is bringing cooling temps and light precipitation to the area.Wednesday: Cloudy with sunny periods and isolated flurries. Precipitation: Trace-5cm. Treeline temperature: Low -7C, High -5 C. Ridge wind Light East. Freezing level: 1800 metres.

Snowpack Summary

Cool temps and cloudy skies reducing the diurnal(daily) swings in snowpack instability. The entire snowpack is isothermal below treeline. The snowpack has remained dry on shady aspects at higher elevations - in deep areas it is generally well settled and bonded, in shallow areas it is facetted and unsupportive.

Avalanche Summary

No new avalanche activity observed or reported locally. Explosive control near Mount Robson Monday produced small avalanches out of steep alpine terrain that scraped down and entrained significant mass in the isothermal snowpack at lower elevations.Anything interesting this weekend?

Confidence

Due to the number and quality of field observations

Problems

Loose Wet

The isothermal snowpack on all aspects below treeline will require several days of cooler temperatures to fully stabilize, human triggering remains possible.

Travel early before the heat of the day, and avoid big slopes.

Aspects: East, South East, South, South West, West.

Elevations: Below Treeline.
