New snow on the range. This fell with strong Southeast winds so this means Wind Slabs are the hazard to watch.
Assess steep slopes appropriately.
With such strong South to Southeast winds, expect Wind Slabs to form in steep, sheltered Northern aspects. These Wind Slabs will be mostly found above 1600m. These Wind Slabs may now sit below softer snow which fell after the wind dropped.
A increase in temperatures, or if the sun makes an appearance may mean Loose Wet slides may occur on steep slopes at lower elevations where enough snow exists.
Small Wind Slabs from explosives at Mt Hutt and Porters previous 24hrs.
It is looking like around 75-90cm at the South of the range tapering to about 40-50cm to the North. Initially the most of the snow came with strong Southeast winds which dropped during the storm. Temperatures rose before things cooled again 08/07. Coverage is patchy with significant pockets of wind deposited snow to very thin patches where the early wind had stripped things back to ground.
Saturday: Fine, apart from some morning valley fog. Severe morning frosts. Light Southerly winds turning Westerly in the afternoon. Freezing level 1400m.
Sunday: Fine. Westerly winds turning Northwest and increasing in the afteroon. Freezing level 1400m rising to 1800m in the evening.
Wind polished surfaces and icy areas will be very slippery. consider Ice axe and Crampons if venturing out.
