Weather Forecast
The forecast calls for continuing snow for the next three days as a SW flow directs itself at the coast. Weather models disagree, but best guess is: Monday â 10-20 cm, Tuesday â 20-30 cm , Wednesday â 10-30 cm. Winds are moderate to strong from the SW and the freezing level hovers near 700 m until Wednesday, when it's expected to rise to near 1800 m.
Avalanche Summary
Explosives triggered numerous size 1-2 slabs on Friday and Saturday in the north of the region. Many of these were on wind-loaded N-NE aspects around 1400-1500 m. At low elevations, natural loose wet avalanches were observed in steep terrain. Poor visibility prevented most operators from observing avalanche activity on Saturday.
Snowpack Summary
Strong winds have redistributed recent storm snow into wind slabs, and rain has saturated the surface of the snowpack to around 1000 m. If temperatures cool, the snowpack below treeline may gain some strength. Above treeline, a buried rain crust and/or surface hoar layer is down about 50 cm. Observations of the strength at this interface have been limited. The November crust near the bottom of the snowpack is generally well bonded, but may still be reactive in areas with a shallow snowpack, or with a very heavy load.
