Low clouds in the morning with cold temperatures. Clouds lifted and broke, with plenty of sunshine, particularly at mid and upper elevations. Temperatures warmed significantly around lunchtime.

Most avalanches were very small loose wet slides or piles of rollerballs from Thursday afternoon and Friday morning.
On sunny aspects, the recent snow has become moist to wet due to warm temperatures and sunshine. It was well bonded to the 3/30 crust. While you can still discern the new snow from the old melt forms, it was integrating well, and a new surface crust was forming,
On Northerly slopes, 6-8" (15-20cm) of recent snow was generally well bonded to the 3/30 crust. Thin melt-freeze crusts and layers of graupel were seen in this snow. These layers failed in some tests, but did not seem to pose a risk as slabs were only a few inches deep.
On all aspects, below the strengthening 3/30 crust, wet large grained spring-like snow (melt forms) were observed. You could even see the "blue" hue due to all the water still in the upper snowpack.
While the mountains went through a decent spring shed cycle last week, plenty of snow still hangs on cliffs and large drippy cornices loom over some slopes. There's still more snow to fall down during warm and sunny weather.
At lower elevations, the snowpack is well transformed to spring conditions. Creeks are opening. Some of them are running deep and fast. There wasn't enough new snow to pose much of a risk from Loose Wet Avalanches.
