Watch for windslabs in lee's as you transition to ridge crest. There have been winds from the North in the past, look for signs of reverse loading.
Spring conditions exist in most location. North aspects may still hold the Persistent problem, be cautious and inspect. This is the time of year to start early and finish early. Watch for warming and direct solar input when travelling through terrain. Check out Avalanche Canada's blog on Spring Conditions for some good tips.

Watch for sheltered northern areas where this layer may still exist. If triggered slabs could step down into the basal layers.
Be mindful that at this time of year any short bursts of solar radiation could be enough to trigger slides.
No recent activity observed or reported.
Wind slabs are evident in the alpine on all aspects. While these slabs are not deep, they could be sensitive to triggering where the underlying surface is a smooth crust. Otherwise, expect a melt-freeze surface layer (or near surface) on all solar aspects as well as all aspects at lower elevations. Higher elevation northerly aspects still hold dry snow. Cornices are starting to sag in the mid-April heat, and some recent collapses have been observed.
Timing is everything. As surface crusts break down during the day the stability will begin to decrease. Start early and finish early.
