Evaluate conditions as you change aspect and elevation.
Wet avalanches are possible on sun affected slopes, and wind slabs remain a concern at higher elevations.
Wind slabs may still be reactive to human triggers, from strong north and westerly winds. Expect loading around ridgeline features.
Loose wet avalanches will become more likely throughout the day on sun affected slopes.
Keep an eye on surface conditions as you travel. As snow becomes moist or wet, minimize your exposure and seek out other aspects.
SATURDAY NIGHT: Partly cloudy with moderate northwest winds. Freezing levels below valley bottom. Chance of isolated flurries.
SUNDAY: A mix of sun and cloud with gusty strong westerly winds. Freezing levels rise to 1500 m with an alpine high of -2 expected.
MONDAY: A mix of sun and cloud with up to 10cm possible, light northerly winds. Freezing levels around 800 m. Alpine high of -5.
TUESDAY: Partly cloudy with isolated flurries possible. Light northerly winds. Freezing levels below valley bottom with alpine highs of -12.
Mild sunny weather will likely continue to cause some wet loose avalanches on south-facing slopes and cornice failures along ridgelines.
There have also been a few small (size 1-1.5) human triggered slabs on north and east facing slopes over the past few days. These slabs have been in the top 20 to 30 cm of recent snow.
Soft snow may be found on sheltered north-facing slopes, but otherwise the surface has a mix of sun crusts on south-facing slopes, wind-affected snow in the alpine, and moist/crusty snow at lower elevations.
See the North Rockies field team's recent post from Renshaw for some photos. The mid and lower snowpack are reportedly strong and well bonded.
