Avalanche Forecast

Moderate - Timing or intensity of solar radiation is uncertain

Mostly clear with freezing levels at valley bottoms and overnight valley temperatures around -18. Warm air has started to develop at higher elevations, between 1400-2100 metres. This warm air is not able to descend into the colder valleys. Forecast upper elevation southerly winds are expected to continue to push warmer air into the alpine. Saturday is forecast to be the warmest day of this inversion for the northwest inland region. Sunday may continue to have alpine temperatures at or slightly below freezing. Clear nights should allow for the snow surface to re-freeze.

No recent avalanches have been reported. With solar radiation and warming forecast for the next few days, loose wet avalanches will become more likely on steep, sun-exposed slopes.

Light amounts (10-15cm) of snow fell last weekend. Variable winds have likely shifted the new snow into wind slabs in upper elevation lee terrain. Although these wind slabs have likely gained strength, I'd remain cautious on steep, unsupported slopes in the immediate lee of ridge crests. Solar radiation has also come into play, and depending on the time of day, steep solar aspects may be moist or refrozen.We're still dealing with a thin, early-season snowpack for much of the Northwest Inland region. Shedin creek snow pillow is at historical minimum snow depth, and Tsai creek snow pillow is setting new historical minimum snow depth. Between 80 and 100 cm of snow can be found at tree-line in the south and west of the region, with closer to 60 cm in the east. A weak basal layer probably exists in most areas, and I suspect that the ongoing cold temperatures have continued to promote faceting in the snowpack, especially in shallow, rocky areas.
