Regions: Coquihalla, Harrison-Fraser, Manning, Skagit.

Wet loose avalanches are possible on steep sun-exposed slopes. Where a thick surface crust exists avalanche activity will be unlikely.

Give cornices a wide berth from above and below.

Confidence

Moderate

Avalanche Summary

No recent avalanche reports as of 4 pm on Tuesday. Strong sunshine and rising temperatures may initiate small, wet loose avalanches on south facing slopes.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network.

Snowpack Summary

Up to 15 cm of new snow overlies the old snow surfaces. This includes a widespread crust which likely exists at all elevations, except on high north-facing slopes. Small pockets of wind-affected dry snow still exist on north-facing alpine slopes. Watch for moist, unstable snow on southerly slopes with sun and warming temperatures.

Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
