Description:
A modest amount of snow (5-10cm) fell several days ago. This snow landed on melt/freeze crusts in many places and may take a while to fully bond to the old surface . A period of moderate to strong Southerly wind in the middle of the week, may have created deposits of wind slab on lee slopes. Exercise caution if you encounter pockets of stiff wind driven snow particularly, on steep slopes and roll overs at higher elevations.

Nothing reported recently but remember that observations are limited at the moment.

Current Snowpack Conditions

Current Snowpack Conditions
Unfortunately, the cover above about 2000m remains patchy. South facing aspects and sheltered gullies currently hold the most snow. A spell of colder temperatures is starting to drive surface and mid pack facet development (loose, sugary snow). While this is not currently a problem, these layers may become an issue when buried by a significant snowfall. Below 2000m, the snow depth tapers quickly due to past periods of warm weather and rain. Cover is very thin to non existent below about 1400m.

Mountain Weather

Mountain Weather
Mainly fine weather is forecast for at least the next couple of days. We return to a NW flow on Friday with light to moderate winds.The freezing level which has been hovering around 1000m is due to climb to 1400m.

Sliding Danger

Slide For Life
Hard crusts are widespread especially at mid elevations 1400m to around 2000m. A slip could lead to a long uncontrolled slide. It is worth throwing ski crampons or an ice axe and crampons into your pack.
