Summary

Weather Forecast

Weather forecasts have been inconsistent in temperatures, cooling rate and precip. What is definitive is that we are in a mild cooling trend. Broken skies and freezing level to rise to 2200m.

Snowpack Summary

Wet surface snow (top 10cm) on all aspects below 1800m. Temperatures start to cool on Saturday evening and you can expect a weak melt freeze crust where snow was previously moist; this may break-down BTL over the day Sunday. The snowpack has remained dry on shady aspects on higher elevations and may be best chance at good riding in the short term.

Avalanche Summary

Valley bottom flooding and surging rivers. No new avalanche activity observed or reported.Anything interesting this weekend? Share with the community on the CAA Mountain Information Network

Confidence

Intensity of incoming weather systems is uncertain

Problems

Loose Wet

An isothermal snowpack exists at all elevations on solar aspects. This will need time to cool and settle before becoming truly trustworthy and natural, and especially human triggering is still possible in the meantime.

Avoid ice climbs exposed to steep rocky terrain on solar aspects during the middle of the day.Start and finish early before the surface crusts melt.

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

Elevations: Treeline, Below Treeline.
