Rain continues to fall as freezing levels rise to mountain tops, creating dangerous avalanche conditions.
On Saturday and Sunday, numerous size 1.5 to 2 natural wet slab avalanches occurred at treeline and below treeline in the Whistler area. Additionally, in the same area in the alpine, two size 1.5 storm slab avalanches were remote triggered in the alpine by nearby explosive avalanche control.
On Friday, several size 1 to 2 skier triggered wind slab avalanches occurred in the Whistler area.
20 to 50 cm of recent storm snow is becoming wet and settling rapidly with warming temperatures and heavy rain. This snow overlies a thick crust on all aspects and at all elevations.
The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.
Cloudy with 20 to 40 mm of rain. South alpine wind, 40 to 60 km/h. Freezing level rising to 2500 m.
Cloudy with up to 10 to 50 mm of rain during the day, up to an additional 40 mm overnight. South alpine wind, 40 to 70 km/h. Freezing level 2500 m.
Cloudy with no new precipitation. Southeast alpine wind, 20 to 40 km/h. Freezing level 1700 m to 2200 m.
Mainly cloudy, up to 12 mm of rain, snow at higher elevations. Southeast alpine wind, 30 to 60 km/h. Freezing level 2300 m.

Terrain and Travel Advice
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
Wet loose avalanches will be likely in steep terrain and where the snow surface is wet.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
The recent storm snow will become wet and heavy as the temperatures rise and rain falls. The underlying crust will likely act as a sliding surface for the wet snow.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Fragile cornices could be further weakened by warm temperatures. Limit your overhead hazard during periods of rain and warming.
Aspects: North, North East, North West.
