Avalanche Forecast

Low

Despite the lack of reports, we suspect a natural avalanche cycle to occur during the peak of the warming event (Monday night into Tuesday).

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Approximately 20 to 40 cm of heavy, rain-soaked snow sits over various layers of crusts and old faceted snow and may also overlie isolated pockets of surface hoar in sheltered areas. A thick crust exists at the base of the snowpack at higher elevations.

Treeline snowpack depths in the range of 80-100 cm in the Coquihalla area.

Monday Night

Cloudy with 40 to 70 mm of rain (potentially wet snow at higher elevations), southwest alpine winds 50 to 70 km/h, treeline temperature 2 °C, freezing level 2700 m.

Tuesday

Cloudy with 30 to 50 mm of a mix of rain and snow, southwest alpine winds 30 to 60 km/h, treeline temperature 1 °C, freezing levels 2100 m and dropping gradually through the day.

Wednesday

Cloudy with no precipitation, southwest alpine winds 10 to 20 km/h, treeline temperature -1 °C.

Thursday

Cloudy with 2 to 5 cm of snow, southwest alpine winds 20 to 30 km/h, treeline temperature -2 °C.

• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Carefully monitor the bond between the new snow and old surface.
• Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
