Weather Forecast
A few more cm of new snow is expected on Monday night for Coastal and Interior regions. Temperatures are expected to drop to about -15 in the alpine by Tuesday morning as a ridge of high pressure moves into the region. Wednesday is expected to be mostly clear, but not as cold as Tuesday. The next system should be on the coast by Wednesday night or Thursday morning.
Avalanche Summary
Reports of natural avalanches up to size 2.5 from northerly aspects. I suspect windslab releases from snow transported by the recent storm.
Snowpack Summary
Heavy rain up to about 1000 metres on Saturday night ended around 0800 Sunday. Cooling since the storm has created a rain crust up to about 1200 metres. There is about 235 cm at 1500 metres. There is an old rain crust that is buried down about a metre that is knife hard and showing old facets above and below. The snowpack is well settled below the rain crust down to the ground. The snowpack in the alpine is highly variable. Strong winds with almost every storm this winter have scoured ridges and knolls down to bare ground, and exposed boulders on some slopes.
