Description:
There is a MODERATE chance for wet loose avalanches today due to forecasted rain fall especially towards the northern end of the range. Should we receive enough rain combined with warming temperatures these wet loose slides could become an issue especially in areas where loose dry recycled powder rests atop an older firm ice crust. Watch areas that have been sheltered from recent winds and elevations generally above 1700m.

Description:
There is a continued LOW danger for isolated wind slabs today. Be suspect of any areas that have received new wind loading, and avoid them like the plague. Recent tests have shown very poor stability in these slabs, and while they are generally easy to spot, and low in volume, they will likely involve high consequence terrain were a skier or rider to get caught in one.

Recent Avalanche Activity

Recent Avalanche Activity
A small wind slab avalanche was triggered by a skier on an easterly aspect two days ago.

If you see any instabilities or even just good skiing, let us know: canterburyavycentre@gmail.com

Current Snowpack Conditions

Current Snowpack Conditions
Depending upon where you dig today you just might see a different snowpack from one place to another. Overall things are looking anemic across much of the range with some higher elevation bowls showing deeper older snowpacks with soft recrystallized powder on top. On south and more sheltered aspects the snowpack looks like it should in late May or early June. The potential problem now lies in the top third of the pack where layers of facets, crusts and in some areas a thinner wind slab exist. In many tests this wind slab is failing with easy to moderate energy and planar shears.

Mountain Weather

Mountain Weather
A very strong northwest system will be upon us today. Expect a challenging day in the mountains with very strong to gale winds, rain and snow depending upon elevation, and much warmer temperatures than we are used to. For more information please check the Metservice link below.

Sliding Danger

Slide For Life
Good skiing can still be found in upper elevation zones especially on east and northeast aspects and bowls in the central and northern parts of the range. Icy patches still exist out there too, so move slowly, and know how to self arrest if you start to slide.
