Points saillants

Enjoy the beautiful spring weather on Saturday, before a brief return to winter on Sunday and Monday.

Remember to pay attention to how the snowpack is reacting to the rising daytime temperatures, and the best risk management strategy is usually to start and finish your trip early.

Snowpack Summary

Up to 10cm of recent snow with variable wind effect remains dry, and overlies a strong midpack above 2400m on shaded aspects. Sunny aspects, and everywhere below 2400m, starts as a supportive surface crust that breaks down with solar input and rising daytime temperatures.
