Northwest Coastal

Stick to conservative terrain free from overhead hazard.

Storm slabs sit over weak layers, increasing reactivity to triggers.

Moderate

• We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.
• Uncertainty is due to the track & intensity of the incoming weather system.

We expect human triggered avalanches to become likely as storm snow accumulates, natural triggers are more likely in coastal terrain or areas that see intense wind loading.

By 4pm Tuesday, storm totals are expected to reach 50 cm in coastal terrain, and taper rapidly inland to 30 cm near Terrace. Storm snow will accumulate over a mix of weak surface hoar and facets, as well as hard wind affected surfaces. At lower elevations, new snow will build over a crust.

The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 250 cm to 350 cm.

Monday Night
Cloudy. 15 to 30 cm of snow. 50 - 70 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Tuesday
Mostly cloudy. 10 to 15 cm of snow. 30 - 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Thursday
Mix of sun and clouds. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

• Don't let storm day fever lure you into consequential terrain.
• Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
• Minimize exposure during periods of heavy loading from new snow and wind.
