Lo esencial

Wind is continuing for the next few days.

Wind Slabs will be present at upper elevations on the Eastern 1/2 aspects and lower down the slope from the ridge.

    Tamaño
    1.5

    Wind Slabs are more dense and contain smaller snow particles due to being tossed around and beaten up by the wind. These Wind Slabs will be found mostly on Eastern1/2 aspects. The stronger the wind, expect to find Wind Slabs lower down the slope from the ridge and in very sheltered zones. Cornices indicate wind direction and could possibly grow quite large with the forecast weather. Watch for denser, hollow sounding pockets of freshly deposited snow on steep slopes above 30 degrees.

    An elevated freezing level and a saturated snowpack from rain mean the sun will react quickly causing roller-balling first then possible Loose Wet avalanches when the sun comes out, on solar aspects and mid to upper elevations. Be aware of this hazard if traveling uphill in these areas.

Recent Avalanche Activity

Nil in the past 24hrs.

Current Snowpack Conditions

Snow coverage across the forecast area is super variable. Up to 150cm in some areas down to rime covered rocks. Warm temperatures will have settled the upper pack somewhat, almost creating a spring like snowpack leaving a firm surface after overnight freezes. Around 30mm of rain to 2000m 22/08 fell then cooled early 23/08 and up to 10cm of snow has fallen to around 1200m.This all came with gale Northwest winds so will have altered the snowpack significantly.

Mountain Weather

Monday: A few showers about the divide, mainly fine with areas of afternoon and evening high cloud elsewhere. Strong Westerly winds turning Northwest and increasing in the afternoon. Freezing level 1500m rising to 2000m in the afternoon.

Tuesday: A few showers. Snow lowering to 1900m in the morning. Strong Westerly 1/2 winds. Freezing level around 2300m.

Sliding Danger

Ice axe and crampons are highly recommended as rain will now turn to ice at low to mid elevations.. Ski Crampons will be required if adventuring on skis or snowboard.

Forecast Confidence

Low

  • The snowpack structure is well understood.
  • We are uncertain due to variable freezing levels.
