Regions: South Coast Inland.

A storm passes the region Wednesday night into Thursday. The storm is convective in nature, so variable amounts of snow may fall. The snow may be reactive to human traffic, where enough of it accumulates.

Confidence

Moderate - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

WEDNESDAY NIGHT: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate southwest wind, alpine temperature -9 C.THURSDAY: Cloudy with snowfall, accumulation 5 to 10 cm, moderate southwest wind, alpine temperature -11 C.FRIDAY: Cloudy with light snowfall, accumulation 1 to 3 cm, light northwest wind, alpine temperature -10 C.SATURDAY: Partly cloudy, light east wind, alpine temperature -9 C.

Avalanche Summary

No new avalanches were observed on Tuesday.

Snowpack Summary

Around 10 to 20 cm of snow on Wednesday night into Thursday will accumulate onto a variety of surfaces. The snow will fall on wind-affected snow in exposed terrain at higher elevations, soft and faceted snow in shaded and sheltered areas, and a melt-freeze crust on southerly slopes.The middle and lower snowpack is generally well-settled.

Avalanche Problems

Storm Slabs

Around 10 to 20 cm of snow is expected by Thursday, which may not bond well to underlying surfaces. Use caution if you transition into avalanche terrain, as the snow may slide easily.

Use caution in wind-loaded pockets, especially near ridge crests and roll-overs.Watch for signs of slab formation throughout the day.Assess the bonding of the new snow with underlying layers as you travel.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
