In sintesi

Conditions are tricky despite the moderate danger rating and sunny weather.

The best and safest riding will be on slopes with soft snow and no slab properties.

Avalanche Summary

No new avalanches have been reported since Friday when two separate parties accidentally triggered wind slabs near Whistler, and whumpfing was described in this MIN report.

Snowpack Summary

Wind-affected snow and wind slabs formed by recent shifting wind can be found on various aspects at upper elevations. Steep sunny slopes may be moist or have a thin surface crust, shady slopes are growing surface hoar.

35 to 70 cm of old storm snow is slowly settling and has remained dry and powdery in many areas with cold temperatures. This snow is sitting on a weak layer that developed in late January: In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may rest on faceted grains or surface hoar.

The mid and lower snowpack is well-settled and bonded with no other layers of concern.
