Watch for changing conditions and signs of instability as you travel.

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.

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.

Wednesday Night

Mostly clear skies. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday

Friday

Up to 5 cm of snow overnight then cloudy with isolated flurries during the day. 30 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 2300 m.

Saturday

Sunny. 30 km/h west ridgetop wind. Treeline temperature +5 °C. Freezing level 2600 m.

• 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.
