FORECAST:
Upper ridge begins to rebuild today but there is some lingering cloud, so unsettled weather in a Southwesterly flow aloft. The freezing level will rise again today with another inversion. Ridge strengthens somewhat Saturday with some cloud and more sun in the mix. Sunday is looking overcast with the chance of some Scottish mist. Monday will see some precipitation with warmer temperatures.
Guesstimates: no precip until Sunday? 0-trace by Monday am, 10-20 cm by Tuesday am above 1500 meters.
AVALANCHE ACTIVITY:
Warm temperatures have also caused a lot of rockfall below tree line.On Wednesday, a natural widespread wet loose avalanche cycle up to size 1 occurred. A cornice failure size 1.5 also occurred triggering a small surface slab on the slope below.
As warm air and sunshine hit the region again Friday and Saturday Expect more natural avalanche activity to occur. The longer the heat sticks around the deeper it drives into the snowpack potentially initiating larger avalanches.
