Thursday, like Wednesday is forecast to have clear sunny skies and a freezing level of around 2500m. It might be possible to trigger wet loose sluffs on the steep sunny ground on Thursday. Move somewhere colder or flatter if the snow starts moving

Watch for any small pockets of wind slab which may remain at the very high elevations.

Wed 13 Aug - A series of avalanching (unsure of type) off Mt Talbot observed in the afternoon.

Summary for week 12th-17th August

Over the 12-13th Aug around 45mm fell as snow (25cm) down to around 2000m with rain below that. The second half of the week had a sustained southerly flow with a low FAFL, down to 700m, with no precip. The FAFL is slowly rising now.

The snowpack is expected to be wet and refrozen below 1900/2000m. Above this the mid-pack may have layers, but the upper pack may be wet and refrozen. There may be a dry layered snowpack on the highest peaks, especially on the southerly half.

Fri 7th to Sun 9th. Up to 25cm fell above about 1700m in northern Fiordland. Expect some slab development in the steep ground near ridgetops. Below about 1700m expect a lattice of rain crusts or even rain-soaked snow at the very low elevations.

More clear ad calm

A refreeze of the wet snowpack has taken place, to high elevations, on all aspects. Take an axe and crampons if you're exploring.

Moderate
