New snow on top of crusts and rain soaked snow are adding to an already complex snowpack. The hazard will be higher on South facing slopes if there is significant solar radiation Tue. Hazard will also increase Wed depending on snowfall amounts.
Summary
Weather Forecast
After receiving 30-40cm over the last 48hr the snowfall will taper off tonight. Tue will be a bit of a lull but then the next system arrives on Wed with possibly another 25cm by Fri. Temperatures will be cooler, with daytime highs in the -5 to 10 ranger. Winds will return to the Waterton 'normal' of strong westerlies for the forecast period.
Snowpack Summary
Sundays rain left moist snow and crust that are now 30-40 under the surface. Below 1900 there is a complex of crusts and moist snow 40-45cm thick. Above 1900m the crusts are more discrete, with dry snow in between. The Feb facet layer is still persistent, down 70-180cm and could still be reactive in places that have not already gone.
Avalanche Summary
Not much avalanche activity has been seen Sun/Mon because of poor visibility. A long audible avalanche was heard off the back of Cameron Lake on Mon. This was likely the storm snow running on the Mar 14 melt freeze crust.
Confidence
Intensity of incoming weather systems is uncertain on Wednesday
