Weather Forecast
On saturday temperatures are expected to warm up with daytime highs around -5C at treeline. Winds are forecast to begin to ease off into the moderate range out of the SW with 3-5cm of additional snow. A new low is building in the gulf of Alaska that may MAY.... give us some more snow early next week.Â
Avalanche Summary
Due to snow and cloudy conditions no new avalanches were observed or reported.Â
Snowpack Summary
Over the past three days up to 30cm of snow has fallen at treeline elevations and above. Lower elevations have only seen about have of that amount. This new snow has fallen under the influence of strong SW winds so widespread windslabs have developed in open areas. At treeline and below the Dec 10th surface hoar later is now down 20-25cm. This layer is only being found in sheltered areas due to previous winds but was large so we suspect it to be reactive where present. Overall the base of the snowpack is weak and facetted with the October crust 20-30cm off the ground.Â
