In sintesi
If the sun comes out from behind the clouds, extended sunny periods will increase the avalanche danger at all elevations.

Overcast conditions are unlikely to lead to any overnight refreeze of the snow pack at lower elevations. As such, solar aspects BTL could be prone to loose snow slides whenever the sun makes an appearance.

Natural and human triggering is unlikely but it is still a good practice to avoid steep, open, rocky slopes with a shallow snowpack.
Weather Forecast
Overcast skies and light snow flurries will occur in the Icefields area with only light accumulations. Temperatures will be colder through Tuesday night and then will rise again with poor overnight recovery in the townsite area. Temperatures will be warmer with less snow closer to the Jasper townsite. Moderate SW winds will continue.
Snowpack Summary
A supportive mid pack consisting of rounded and facetted layers is bridging the weak depth hoar/facet layers that make up the lower snowpack. Wind slabs continue to develop in sheltered alpine locations from moderate to strong SW winds.
Avalanche Summary
A single size 1 loose avalanche occurred in the alpine on a solar aspect originating out of rock cliffs.
Confidence
Freezing levels are uncertain
