Avalanche Forecast

Moderate - Recent weather patterns have resulted in a high degree of snowpack variability within the region.

Lingering flurries continue until Tuesday afternoon.

MONDAY NIGHT: Cloudy with isolated flurries and up to 5 cm of snow, moderate west wind, treeline temperatures drop to -8 C.

TUESDAY: Some isolated flurries in the morning then clearing in the afternoon, moderate northwest wind at ridgetops, treeline temperatures around -6 C.

WEDNESDAY: Mostly sunny, light southwest wind, treeline temperatures around -6 C.

THURSDAY: Flurries with 5-15 cm of snow, strong southwest wind, treeline temperatures around -4 C.

Sunday night's storm resulted in a natural avalanche cycle, with storm slabs up to size 2.5 on wind loaded features. Explosive control on Monday produced several size 2 avalanches (roughly 50 cm thick). On Sunday, during the early stages of the storm, there were several reports of size 1-1.5 human triggered storm slab avalanches (10-25 cm thick). Looking forward, strong wind has likely left reactive slabs at upper elevations.

The weekend's storm delivered 30 cm to the Whistler area and up to 60 cm in deeper areas further west and south. Alpine terrain is likely heavily wind-affected, while a rain crust will form below 1300 m. This snow buried a layer of surface hoar and crusts, but the snow is expected to bond quickly to these layers. The lower snowpack has become strong and bonded.

• Avoid freshly wind loaded terrain features.
• Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
• Investigate the bond of the recent snow before committing to your line.
