Travel and Terrain Advice
The winds have been strong enough to create Windslabs at lower elevations, in areas where you don't find Windslabs as often. Assess for new wind loading at all elevations as you travel through the mountains today. The strong winds have been causing lots of tree bomb failures over the past 2 days, watch out for the hard blocks of snow underneath the trees.

概要
Avalanche
A size 1 Windslab was triggered by a skier on a cross-loaded South aspect BTL on Nito Nupuri yesterday.
Snowpack
30cm of new snow overnight with Strong Westerly winds which will have transported the new snow on to the slopes facing away from the wind, creating new Windslabs and Cornices. The area has experienced a lot of strong wind in the past 48 hours, with several changes in wind direction, from East to North, and most recently to Westerly winds. There is a thin crust down 30-40cm on all aspects below ~500m, and on steep solar aspects below ~1000m.
Weather
Overcast skies and continued snowfall through the day with Strong Westerly winds at higher elevations. Temperatures are forecast to remain in the -10 range at TL. Heavy snowfall expected tonight across the region.
