    New snowfall and strong winds may form new wind slabs in high elevation lee terrain. Only 5 cm of new snow is expected. Use extra caution if more snow accumulates.

Confidence

Fair - Intensity of incoming weather systems is uncertain

Weather Forecast

A weak pacific frontal system will bring light snowfall (up to 5cm) Wednesday night and into Thursday. A clearing trend is forecast for Friday and Saturday as a ridge of high pressure rebuilds in the eastern Pacific. Winds are expected to be strong from the southwest on Thursday, and then become moderate from the northwest on Friday and Saturday. Daytime freezing levels should hover around 1500m for the forecast period

Avalanche Summary

No new avalanches have been reported. Small wind slab avalanches may form in response to light snowfall and strong winds on Thursday.

Snowpack Summary

On high north-facing terrain. light amounts of cold, lower density snow overlie a widespread thick hard crust. Below about 2000m there is no snow on the crust and surface runnels show the effect of last week's rain showers. Sun-exposed slopes became moist, or wet with recent daytime warming and solar radiation and are also likely refrozen. Below the surface crust, the snow may still be moist; however, the mid and lower snowpack are generally strong and well-consolidated. Most of the terrain below treeline is below threshold for avalanche activity.
