Regions

Jasper.

Overnight temperatures are not cold the next two nights. The day has the potential to start warm plus could be light rain up to 2400m. Tackle the mountains early and get down early as the hazard increases by the late afternoon.

Weather Forecast

Sunday night will be clouds with clear periods, no new snow, -3C, light Southwest winds, and 1700m freezing level. Monday could bring flurries, 6cm of snow, +1C, light gusting moderate Southwest winds, and 2400m freezing level. Tuesday will be similar to Monday. Wednesday could be scattered flurries, 4cm of snow, and 1900m freezing level.

Snowpack Summary

Thin temperature crust on steep solar aspects and potentially 5-15cm soft snow over previous wind surfaces and crusts more likely found on North aspects. Limited wind redistribution occurred from brief Southwest winds early last week. Several hard crusts in the upper snowpack and a well consolidated mid-pack in deep snowpack areas.

Avalanche Summary

Several loose wet avalanches up to size 1.5 in the zone and with neighbors. Consult the Mountain Information Network for recent observations, and please consider submitting a MIN report if you observe any new activity.

Confidence

Freezing levels are uncertain on Monday

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
