Weather Forecast
The storm will continue to bring heavy precipitation and strong to very strong southwest winds for the forecast period. High freezing levels from Tuesday are expected to drop back to valley bottoms by Wednesday morning.
Avalanche Summary
A couple of natural size 2.0 avalanches were reported on steep NE and SE aspects at and below treeline. Explosive control produced a low elevation avalanche size 2.0 on a south aspect, and a size 3.0 avalanche at 1250 metres on a south aspect. We are not sure what depth or sliding surface the size 3.0 released.
Snowpack Summary
Heavy snowfall and strong southwest winds are building new windslabs and storm slabs above the recent storm snow that has consolidated into a slab. The old windslabs are on south through west aspects, and they are stiff and continue to be easily triggered. New windslabs are building on north through east aspects, making travel a bit tricky; limited options exist for avoiding both types of windslab. The deep snowpack is considered to be well settled with no persistent layers of concern.
