Travel and Terrain Advice
Look for fresh wind loading and pockets of windslab particularly at higher elevations. Early season hazards remain at all elevation bands but particularly in the BTL with open creeks, sink holes, roots, sassa, bushes etc across the region.
Avalanche Problem
ウインドスラブ Wind slab
Westerly winds have continued loading leeward slopes.
概要
Avalanche
No new avalanches have been reported in the past 24 hours
Snowpack
Westerly winds in the alpine and treeline have continued to load leeward slopes. Storm snow is settling and bonding and increases in density from the surface down to the sassa/ground interface. A deteriorating crust exists at this interface but is unreactive.
Weather
Moderate to strong NW winds continue today bringing light snow showers. Skies are forecasted to be cloudy or overcast for most of the day with cool temps. A high of -3C is expected in the valley today. Winds are expected to taper off in the late afternoon / evening with no notable snow expected overnight tonight.
