Another day to investigate new snow amounts and reactivity before committing to avalanche terrain. Expect the greatest hazard on lee slopes at high elevations.
New snow and elevated winds should form a new storm slab problem to manage on Monday. Expect hazard to increase with elevation and to be greatest in leeward terrain.
Observations since Saturday's storm are limited, however ski cutting in the North Shore did yield small wet loose avalanches. No slab activity has been reported.
10 - 20 cm of heavy new snow and high winds Sunday night should make for a reactive wind slab problem needing to be managed on Monday.
By Monday morning, 10 - 20 cm of new snow (increasing with elevation) should accumulate on a crust forming on rain-soaked surfaces at most elevations. It may add to a thin cover of dense new snow in the alpine.
A late-January weak layer (hard crust, facets, or surface hoar) is buried 80 to 120 cm deep, this layer should be entombed beneath a firm crust in most areas, with some uncertainty around the highest elevations of the region.
The lower snowpack is strong and bonded.
Sunday Night
Cloudy with wet flurries bringing 10 - 20 cm of new snow, increasing with elevation, rain below about 1200 m. 30 - 60 km/h southwest ridgetop wind. Freezing level 1500 m.
Monday
Clearing over the day, clouding over in late afternoon. 20 to 50 km/h southeast ridgetop wind, increasing. Freezing level rising from 1200 m to 1600 m.
Tuesday
Partly cloudy with 10 - 20 cm of heavy new snow from overnight, increasing with elevation. 10 - 20 km/h variable ridgetop wind. Freezing level 1200 - 1400 m.
Wednesday
Becoming sunny. 20 - 40 km/h southeast ridgetop wind. Freezing level shooting to 2500+ m.
