Unbelievable weather at Arthur's Pass at present.
Yesterday they tallied up 92.5mm of rain with a high wind gust of 98.1k/hr (WU) with temps more likened to winter values. 12.6 High and 8.4 low.
Mr Kates website shows even higher Rainfall and wind gust values of 119mm and 106k/hr respectively which I would envisage to be more accurate than WU.
Today the 2nd the rainfall total at WU so far is 140.7mm.Copied from Mr Kates website:Wednesday 2/01/2013: Very heavy rain (100mm from midnight to 0700hrs - 300mm++ and building); expected to ease by evening with snow levels falling to 1500m. Showers clearing tomorrow.
Climbing conditions are poor after heavy rain to high level soaking the snowpack with another storm cycle presently upon us (gales on tops).
Avalanche risk is HIGH. Rainfall has penetrated the snowpack to high level, with further heavy rain forecast. Large wet sluffs have been running on loaded southern aspects. Avoid avalanche terrain and traps!
Snowline is now receding and thinning very rapidly, however snowpack on southern half remains fairly deep for this time of year.
Some crevasses and bergschrunds are starting to form in steep terrain - in both permanent and non-permanent ice areas. Rain has undermined lower altitude snowpack especially about gully systems - care required! Don't be tempted to "butt-slide", this is the season for them becoming uncontrolled mini-avalanches (bad news in poor run-out areas)!
