Weather Forecast

Dry conditions and a mix of sun and cloud are expected for the forecast period as a ridge of high pressure becomes rooted over the south coast. Ridgetop winds should be moderate to strong from the west on Sunday becoming light on Monday and Tuesday. Freezing levels will hover at about 3000m on Sunday and Monday, dropping to about 2000m on Tuesday.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Information coming from this region has been extremely limited; however, reports suggest there is about 70cm of snow at 1600m in the Duffey Lake area and about 120cm at the same elevation on the Coquihalla. Terrain below treeline is reported to be mostly below threshold for avalanche activity.Modest storm accumulations from last week week have likely gained considerable strength and a daily melt-freeze cycle may be occurring on steep, solar aspects.A few crusts may exist deeper in the snowpack, although observers are not identifying them as layers of concern at this time.

Problems

Loose Wet

Sunny breaks and warm temperatures over the next few days may trigger loose wet avalanches on steep sun-exposed slopes.

Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.>

Aspects: North, North East, East.

Elevations: All elevations.
