Avalanche Forecast

Moderate

• We are uncertain about forecast precipitation amounts.

No new avalanches have been reported.

With up to 20 cm of new snow and strong winds in the forecast, the danger has been elevated. This means large natural avalanches are possible and human-triggering is likely.

Observations are still limited, so be sure to post yours to the MIN if you get out!

Up to 20 cm of new snow accompanied by strong southerly winds is expected overnight and through Tuesday. The highest snowfall amounts are for the White Pass area, with lesser amounts inland.

A crust with weak surface hoar overtop may be found 15 to 40 cm deep in sheltered areas. Wind slabs may be more reactive where they overlie this layer.

A weak layer of facets is buried 70–200 cm. It remains a concern where the snowpack transitions from thin to thick in White Pass and is the primary issue in shallower inland areas with basal depth hoar.

Monday Night

Cloudy. 1 to 4 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -3 °C.

Tuesday

Cloudy. 5 to 15 cm of snow, with highest amounts for White Pass area. 50 km/h south ridgetop wind. Treeline temperature -2 °C.

Wednesday

Mostly cloudy. 5 to 10 cm of snow. 50 km/h south ridgetop wind. Treeline temperature -2 °C.

Thursday

Mostly cloudy. 3 to 4 mm of precipitation as snow or rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level rising to 1300 m.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
• Avoid areas where the snow feels stiff and/or slabby.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
