Avalanche Forecast

On Thursday, numerous natural dry loose avalanche (size 1) were observed from the Coquihalla highway. No other avalanches were reported, but observation have been limited by stormy weather.

If you head into the backcountry, please consider submitting a MIN report.

Up to 30 cm of recent, low-density snow has been redistributed by variable alpine winds. Below the new snow are various old surfaces, including firm wind-affected snow, faceted crystals, and surface hoar, all of which may prolong the bonding between new snow and underlying surfaces.

The mid and lower snowpack contains various old crusts and is generally well-settled and stable.

With recent snowfalls, lower elevation areas may now be at the threshold for avalanches.

Clear periods, no new precipitation. Alpine wind south 5 to 25 km/h. Treeline temperature -1 °C, with an above freezing layer in the alpine.

• Approach lee and cross-loaded slopes with caution.
• Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
• Closely monitor how the new snow is bonding to the old surface.
