Highlights

It is important to keep in mind that LOW avalanche danger is not the same as NO avalanche danger.

Carry avalanche rescue gear (transceiver, shovel and probe).

    Southerly winds may shift light density snow. Isolated pockets of Wind Slab could exist. These slabs are most likely to be found on North facing slopes above about 1700m. Watch for deposits of stiff snow and avoid them particularly, if the terrain is steep and complex.

Recent Avalanche Activity

No avalanche activity reported recently. A widespread cycle of Loose Wet avalanches occurred last week.

If you see evidence of avalanches in the back country please enter a Public Observation.

Current Snowpack Conditions

A few cm's of fresh snow over the past 48 hours. Snow at upper elevations 12/8 (15 - 25cm) in the West and less further East. Rain to about 1850m on the 12/8. Melt/freeze crusts have been forming. The underlying pack is mostly well consolidated. Facets (weak, sugary forms) have been found in places. These pockets of questionable strength appear to be isolated and are most likely to exist on slopes facing East to South. You would be wise to do some investigation before committing to steep, shady terrain.

Mountain Weather

Monday - fine in the morning. A few showers possible in the afternoon. Light to moderate Southerly winds rising to 50 kph at upper elevations. Freezing level - 700m rising to 1300m during the day.

Sliding Danger

A significant sliding danger exists at present. Icy crusts are widespread below about 1850m. These slick crusts may now be covered by a thin layer of fresh snow. The underlying pack remains shallow especially, at lower elevations. Rocks and icy areas may be lurking below a thin cover of snow. Carrying ski crampons and/or an ice axe and crampons is recommended.

Forecast Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
