Points saillants
The warm weather is taking a toll on our snowpack. Ski quality is poor and avalanche hazard is expected to vary with the warm temperatures and sun. Not a great time to be out in avalanche terrain.

With no overnight refreeze we can expect this problem to start early in the day at treeline and below treeline. Wet slabs may become a problem as well. Avoid steep solar aspects if the sun comes out.

As the snowpack warms up, remember that this layer will be easier to trigger. Cornices, loose wet, wet slabs are all potential triggers at this point.
Confidence
Fair - Timing or intensity of solar radiation is uncertain on Friday
Weather Forecast
The warm weather will linger overnight. The freezing level will hover around 2000 for the next 24hrs. Tomorrow will be warm and windy with no new snow.
Avalanche Summary
Isolated loose wet avalanches were noted from steep solar aspects in the afternoon.
Snowpack Summary
The warm temperatures have started to have a sustained effect on the snowpack. By noon today, the valley bottom was moist and isothermal by mid-afternoon. Treeline and lower alpine elevations also have moist surface snow on all aspects. Southern aspects are suffering from the same soar effect, but the cloud cover has helped slow it down.
