South Coast Inland.
Watch out for isolated wind slabs in the alpine. The surface snow may moisten quickly and form loose wet avalanches during sunny periods.

Avalanche Summary
Explosives triggered small cornice chunks on northerly ridges on Monday. The chunks did not trigger slabs on the slopes below.If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!
Snowpack Summary
Around 15 cm of recent snow fell with strong westerly wind, forming wind slabs in lee terrain features at alpine elevations. This snow may overly weak and feathery surface hoar in isolated areas. Heat from the sun and an increasing freezing level will likely moisten alpine snow on southerly aspects. Below around 1800 m, the snowpack is consolidated and rapidly melting.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Loose Wet
Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
