Weather Forecast

Time to hang the flip flops back up as the strong, gusty winds subside and shift from SW to North. Increasing pressure, gorgeous blue skies and arctic temps to dominate the forecast through the week.

Snowpack Summary

14.5cm of storm snow, re-distributed by steady moderate to strong SW winds, loading N to NE aspects on an already stressed facet interface down between 20 to 50cm. Hard windslab over a weak mid-pack, over an even weaker facet and depth hoar base to ground.

Avalanche Summary

No new avalanches observed or reported.
