Weather Forecast
Temperatures dropped and will continue to drop overnight; the forecasted high for Sunday, -31°C. Mix of snow and cloud with a significant inversion forecast. May be worth getting out of the valley bottom and into warmer temps above; warm like -20°C, (slightly better than -31)!A detailed mountain weather forecast is available from Avalanche Canada.
Snowpack Summary
40cm new snow throughout the forecast region. This puts the Jan18 buried surface hoar, down 50cm. Previous to this storm a strong midpack was bridging the basal weakness. Storm snow may overload that bridging and, large avalanches could be expected to travel full path if triggered. Avoid all avalanche terrain until the new snow has time to settle.
Avalanche Summary
Poor visibility through the forecast region. No new natural avalanches observed in the Icefields. Forecaster's sympathetically triggered multiple sz 1.5 to 2 on the same control route. Highway avalanche control had similar results, up to size 2 and burying the road. Help forecast - share observations HERE, on the Mountain Information Network!
