Avalanche Forecast

Moderate - Uncertainty is due to the timing of the incoming weather system.

Friday night: Mostly clear with clouds moving in later in the evening. No precipitation. Winds light from the south. The overnight temperature will be -7°C. 

Saturday: Lingering moisture in the atmosphere will result in a mostly cloudy day. Wet flurries are possible amounting to 2cm of snow. Winds will be moderate from the south. Temperatures will start at around -5°C in the morning and rise to -1°C by the afternoon. 

Sunday: Warm and moist as the storm rolls in. Mostly cloudy until the early afternoon with the potential for clearing later in the afternoon. 5-15cm of new snow overnight Saturday and into Sunday morning with freezing rain possible at highway elevation. Moderate to strong winds from the south. Temperature around -2°C overnight rising to 0°C 

Monday: Clear and sunny. No precipitation. Light north winds. A low of -12°C and a high of -8°C. 

The most recently reported avalanches in White Pass are now 48-72hrs old. 

We have 15-30cm of low density snow sitting on old firm surfaces. On some north aspects in the alpine, this snow exists as firmer wind slab. The bond between this snow and these firm surfaces continues to improve daily. On steep, south aspects at treeline and below, there is potential for the existence of a thin sun crust. 

The lower snowpack is well bridged and it is unlikely that avalanches will be triggered on weak, sugary crystals near the ground at this time. 

• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
• Caution around slopes that are exposed to cornices overhead.
