Summary
Weather Forecast
The next storm is forecast to wash over the North Coast on Tuesday before a ridge builds bringing drier conditions. Up to 5cm is expected overnight Monday near Terrace with another 10cm forecast by Wednesday morning. Coastal areas could see almost twice as much during through the storm. Thursday is expected to be mainly dry. Freezing levels on Tuesday will fall from 1500m to 500m as you move inland, with a cooling trend expected for the entire region through the forecast period. Winds will be strong from the south on Tuesday becoming light by Wednesday and variable by Thursday.
Avalanche Summary
We've receive reports of several natural and skier triggered avalanches ranging from size 1-2 from across the region. It sounds like the surface hoar is starting to wake up!
Snowpack Summary
The forecast snow will fall on a complex upper snow pack. The top 100 cm consists of at least 3 distinct buried surface hoar layers, weak faceted snow, and possibly thin sun crusts on some solar aspects. Recent winds have also wreaked havoc in wind exposed terrain producing hard or stiff slabs and fresh soft slabs in lee and cross-loaded terrain, and scouring windward slopes at ridgetop.
Problems
Storm Slabs
The new snow will fall on a variety of old weak surfaces including surface hoar in the alpine. I would tread lightly until we get a good feel for how the snowpack is reacting.
The new snow will require several days to settle and stabilize.>Avoid freshly wind loaded features.>Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.>
Aspects: All aspects.
