Isolated areas of windslab have been reported in alpine areas, so anyone up on the high peaks should be watching for this. Additionally we advise climbers to avoid south and west facing ice climbs in gullies - rockfall and wet sluffs can be expected.
Summary
Weather Forecast
Westerly flow continues with a gradual falling of freezing levels over the main ranges on Thursday. 0-5 cm of snow (rain?) is expected overnight on Wed, and by Thursday we expect cloud cover and strong alpine winds to keep the higher elevations cool. Friday shows a dramatic warm up when the sky clears.
Snowpack Summary
Generally a well settled snow pack exists with moist snow on solar aspects below 2000 m. Isolated wind slabs may be found near ridge tops in the alpine.
Avalanche Summary
No new avalanches reported or observed.
Confidence
Problems
Loose Wet
The warm temperatures will create wet sluffs on south facing slopes and gullies at and below treeline. Isothermal conditions may develop at below treeline elevations.
Aspects: North, North East, East.
Elevations: Alpine, Treeline.

Wind Slabs
Recent winds have moved small amounts of dry snow into isolated pockets of windslab in higher alpine areas. Watch immediate leeward slopes, and slope test on smaller slopes adjacent. Several skiers have been caught in small ones this week.
Aspects: North, North East, East.
Elevations: Alpine.
