Regions: Northwest Coastal.

Welcome to winter! It's that time of year when winter is slowly winding up and observations are limited. Due to limited data it is CRITICAL to supplement this information with your own observations. Please post your observations to the MIN.

Confidence

Low - Due to the number of field observations

Weather Forecast

FRIDAY NIGHT: Cloudy with light precipitation, light southeasterly ridgetop winds, freezing levels around 700 m. SATURDAY: Cloudy with light precipitation, strong southeasterly ridgetop winds, freezing levels around 800 m. SUNDAY: 5-10 mm of precipitation throughout the day, strong southeasterly ridgetop winds, freezing levels rising to around 1200 m.MONDAY: 15-25 mm of precipitation throughout the day, strong southeasterly ridgetop winds, freezing levels rising to around 1500 m.

Avalanche Summary

No recent avalanches were reported in this region. However, we currently have very limited observations in this region. Please submit your observations to the Mountain Information Network (MIN).

Snowpack Summary

Many areas in this region only have enough snow to ride (or avalanche) in the alpine elevation band. There is an average of 60-110 cm of snow in the alpine which decreases dramatically with elevation where the primary hazards are rocks, stumps, and open creeks. For those areas that have more snow, remember, "If there is enough snow to ride, there is enough snow to slide." We currently have very limited snowpack observations within this region and it is critical to supplement this information with your own observations.5-15 cm of recent storm snow is sitting on a crust that was formed during last weeks temperature inversion. There is likely an early season crust near the bottom of the snowpack.

Avalanche Problems

Wind Slabs

The slopes that have the most snow to ride, may also be in areas most likely to trigger wind slabs, such as gully features below ridgetops.
Stay alert to changing conditions with elevation.Avoid areas where the snow feels stiff or slabby.Avoid wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, West, North West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
