Wanaka

Some fresh snow over the past 24 hours particularly, in the West of the region.

Pockets of Wind Slab may exist especially, on slopes facing East to South above about 1900m.

No back country avalanche activity reported recently. A small (size 1) Wind Slab was triggered with explosives at Treble Cone 20/7 Aspect East, Elevation 1650m.

If you see evidence of avalanches in the back country please enter a public observation.

In general, the snow pack appears stable. Relatively warm temperatures over the past few days have helped the stabilisation process. The flow of back country information is beginning to increase as more parties head out. Buried rime crusts and facets (weak, sugary forms) have been found in places. These pockets of questionable strength are most likely to exist in steep, shady areas (facing East to South). Loading over the next few days will test these layers.

Wednesday - showers falling as snow down to 1700m. North West/Westerly gales easing in the morning but increasing again at night. Freezing level - 1900m.

Be prepared to encounter very firm or icy areas. These slick surfaces are most likely to be found below about 1700m but may exist elsewhere. Many West facing slopes and ridge lines have been stripped by the wind. Carrying ski crampons and /or an ice axe and crampons is a good idea. Overall the snowpack remains shallow with many exposed rocks, open creeks and deep hollows. An uncontrolled slide could have nasty consequences.

Moderate

• We are uncertain about forecast snowfall amounts.
• We are uncertain due to the variability of wind effect on the snowpack.
