Travel is safer early in the day. Expect crusts to break down quickly with daytime warming and solar input, leading to dangerous avalanche conditions on all aspects.
Summary
Weather Forecast
Full sun today with freezing levels rising to 2100m. Ridge winds vary from light to moderate from the NW. Clear skies and cooler temps may promote a refreeze of the snowpack tonight with freezing levels dropping to 1400m. Warm daytime temperatures will persist into next week. The high pressure ridge will break down on Tuesday bringing light rain.
Snowpack Summary
Daytime warming turned the recent storm snow into a 30cm moist layer. There was no full refreeze last night, but under clear skies a weak surface crust likely formed. Below the crust the upper ~70cm of snow is warm, moist and weak. Extreme southerly winds have likely spoiled any remaining north facing powder stashes leaving touchy wind slabs.
Avalanche Summary
Several loose wet avalanches were observed in the highway corridor up to size 2.5. Some time yesterday evening, a large mid-elevation glide crack released on Mt MacDonald creating a large size 3 avalanche.
