Recent snow has seen mild wind effect. Wind slabs have been soft and specific to immediate lees of ridge crests. They may remain triggerable by riders on Tuesday.
Watch for unstable snow on isolated terrain features. On Tuesday, this includes small pockets of wind slab in immediate lees of ridgecrests and moistening snow on steep solar aspects during periods of strong sun.
Spring is a dynamic time of year where conditions can vary widely and change rapidly. Carefully assess your local conditions and pay attention to how the weather is affecting the snowpack throughout the day.

Loose wet avalanches will become increasingly likely on steep solar aspects as the surface becomes moist or wet with strong sun.
Lots of loose dry sluffing was reported in MINs over the weekend. A couple of small (size 1) skier-triggered storm slabs were reported in immediate lees of ridgetops and convexities.

A moist or crusty surface has likely formed on southerly aspects and below 1000 m. 30 to 50 cm of recent snow (above 500 m) appears to be bonding well to an underlying melt-freeze crust. The middle and lower snowpack are strong and well-bonded.
