Watch for signs of instability throughout the day as temperatures continue to rise well above 0 °C. Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
Up to 25 cm of recent snow, overlies a rain crust at all elevations which provides an excellent bed surface for avalanches. Watch for signs of instability increasing as temperatures rise through the day.
Several natural, size 1, loose wet avalanches were observed on all aspects on Sunday.
Thank you to everyone who has been sharing observations on the Mountain Information Network. All the information and photos are very appreciated by forecasters!
10 to 25 cm of storm snow sits overtop a widespread thick rain crust. Below the crust, the snowpack is generally well consolidated.
Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards at or just below the snow surface across all elevations.
