As the temperature drops so will the avalanche danger, but be aware if the sun comes out and the snow starts to become moist.
Weather Forecast
Forecasts show the start of a cooling trend into next week as the ridge of high pressure moves east. On Saturday at the Columbia Icefields Area; alpine highs of +2C, increasing clouds, freezing levels at 2500m with light ridge winds. Continued cooling and increasing cloud cover for Sunday and some light precipitation is in the forecast on Monday.
Snowpack Summary
As of Friday afternoon there is wet surface snow on solar aspects at treeline and alpine, unsupportive slush below treeline. As the temperatures start to cool on Saturday expect a melt freeze crust where surface snow was previously moist. The snowpack remains dry on shady aspects at upper elevations.
Avalanche Summary
Many solar aspects at TL and below have slid and continue to slide around the forecast region with high freezing levels on Friday afternoon. Nearly no activity has been observed on Northern aspects, especially in the Alpine.
Confidence
Timing or intensity of solar radiation is uncertain
Problems
Loose Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
Wet Slabs
Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.
