Avalanche Summary

A few small (size 1) avalanches were reported on Tuesday and Wednesday including:

Wet loose avalanches on sun-exposed slopes and at low elevations.
Human-triggered wind slabs on north-facing slopes.

Snowpack Summary

5 to 15 cm of dry snow may be found on north-facing slopes, otherwise, the upper snowpack consists of various melt-freeze layers.

The facet/crust layer that caused large avalanches in March is buried 100 to 150 cm deep and is unlikely to trigger under the current conditions.

Terrain and Travel Advice

Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
Back off slopes as the surface becomes moist or wet with rising temperatures.
Minimize your exposure time below cornices.
