Points saillants

Areas of wind slab are possible, around terrain features and just off ridgetop, especially at the highest elevations.

If you are heading into avalanche terrain, take a conservative approach. Even a small avalanche could have a nasty consequence, as runouts are so rocky.

Recent Avalanche Activity

Loose dry activity could be heard from the cliff bands with sun, above the Milford Track 7 July.

Current Snowpack Conditions

There is a thin snow cover below 1800m, (observed from flight around Milford Track and neighboring valleys to the east 7 July).

Est. 50-80 cm of snow above 1800m from 3-5th July storm, with less at lower levels, to about 15cm at 1100m.

The first snow fall of the winter was on 24/25th June, with about 10cm at 800m in the South of the forecasting area. There was less snow in the North, estimating about 10-20 cm above 1600m, on tussock, rock and slabs.

Mountain Weather

Saturday - Fine apart from a few morning showers about the south coast. Light winds.

Freezing level - 1800 metres north of Te Anau in the morning, otherwise 1300 metres.

Sunday - Fine, but becoming partly cloudy with isolated showers in the morning.

Wind - Northerly 30 km/h developing in the morning, rising to gale 65 km/h in the evening, but gale 85 km/h about the south coast

Freezing level - 1400 metres, lifting to 1800 metres in the east for a time in the morning and afternoon.

Sliding Danger

Icy conditions are to be expected, on slabs and at higher elevations, which have been stripped back by S/SE winds. Take ice axe and crampons.

Forecast Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
