    Fresh storm slabs are expected to be highly sensitive to triggering and particularly deep and touchy on wind-loaded slopes.

Avalanche Summary

The likelihood and size of slab avalanches will increase with continued snow and wind and warming temperatures. Natural avalanches are likely during periods of heavy loading from snow, wind and rain.

Snowpack Summary

Much of the region received around 50cm of of fresh snow over the past couple of days, which is bonding poorly to a sun crust on southerly aspects and surface hoar on shaded aspects. Fluctuating temperatures have likely resulted in weaknesses within this recent storm snow and southwesterly winds have likely deposited deep and touchy wind slabs in exposed terrain. The mid and lower snowpack appear to be well settled and strong.
