Travel and Terrain Advice
The first day of March is forecasted to bring warm temperatures and sunshine the result of this will be heavy variable snow conditions at lower elevations. West expect a overnight surface freeze to have occurred possibly resulting in a breakable curst in the morning. Solar aspects will warm quickly with the possibility of wet loose activity in steep terrain, identify terrain traps below you if crossing sun and temperature affected slopes. The alpine contains wind slabs on the eastly half and firm wind stripped conditions in the west.
Avalanche Problem
ウインドスラブ Wind slab
Moderate to strong northwesterly winds have continued to build wind slab in the alpine on easterly aspects. Look for signs of fresh wind load and areas of high snow accumulation to identify terrain to avoid.
点発生湿雪雪崩 Wet Loose snow
Temperatures will again rise above freezing today with the possibility of loose wet activity on steep terrain from early in the day. Lower elevations will become un-cohesive and heavy from mid morning.
全層雪崩 Glide slab
Glide slab avalanches remain a concern with fluctuating temperatures promoting a melt freeze cycle. Limiting exposure beneath these features is essential due to their high consequence unpredictable nature.
概要
Avalanche
No new activity has been reported across the region on the 28th
Snowpack
A warm sunny day yesterday resulted in all aspects becoming moist and heavy below 900 metres. At upper elevations wind slabs continue to grow on easterly aspects as westerly winds transport any snow available onto lee slopes. Windward aspects are mostly stripped and firm. We expect a light variable breakable curst to have formed on the snow surface overnight.
Weather
The freezing level will climb to 700m today, with broken sunshine expected in the morning. Winds will remain light to moderate from the north west.
