Watch for reactivity in the remaining pockets of dry snow in the alpine. Elsewhere a surface crust will limit avalanche activity.
Give cornices space - on ridgelines and on the slopes below.

Avalanche Summary
Strong sunshine and rising temperatures produced loose wet avalanches to size 2 over the past few days. Reactivity within the recent wind-affected storm snow also continues, with natural cornice falls triggering slabs on the slopes below to size 2.5.
While cooler temperatures on Monday will limit the potential for wet avalanche activity, reactivity may linger in high elevation, north facing terrain features where dry snow remains.
Snowpack Summary
A widespread surface crust likely exists at all elevations, except on high north-facing slopes which is expected to limit avalanche activity. Small pockets of wind-affected dry snow still exist on north-facing alpine slopes, up to 40 cm deep.
Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.
Weather Summary
Sunday Night
Partly cloudy. 30-50 km/h westerly ridgetop wind. Freezing level drops back to 1500 m by morning.
Monday
A mix of sun and cloud with 30-50 km/h westerly winds. Freezing levels around 1200 m. Treeline temperatures of -3 °C.
Tuesday
Mostly clear skies with 10-20 km/h northerly winds. Isolated flurries possible. Freezing level around 1300 m. Treeline temperatures of -3 °C.
Wednesday
Mostly clear skies with 10-20 km/h northerly winds. Freezing level around 1500 m. Treeline temperatures of -2 °C.

Terrain and Travel Advice
- Caution around slopes that are exposed to cornices overhead.
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
Problems
Wind Slabs
Wind affected dry snow may remain reactive to human triggers. Weak cornices also exist above these slopes, and have the potential to be destructive on their own, or to trigger large avalanches on the slope below.
Aspects: North, North East, North West.
Elevations: Alpine.
