Avalanche Forecast

No new avalanches have been reported.

During the storm on Monday and Tuesday, storm slabs up to size 2.5 occurred. Check out this MIN report.

On Tuesday near Mount Washington, several skier-triggered storm slabs up to size 1.5 were reported from steep or wind-loaded terrain at treeline.

Wind slabs may still be reactive to human triggering in wind-loaded features.

Up to 90 cm of recent snow has been transported into wind slabs on south- and east-facing slopes by strong northwest winds. Expect to find pockets of dense and deep wind slab in wind-loaded terrain and crusts or bare ground in high-elevation exposed terrain.

The remainder of the snowpack is strong, with numerous hard melt-freeze crusts.

Treeline snow depths generally range from 50 to 150 cm. Snow depth diminishes rapidly below 500 m where there has been more rainfall.

Saturday Night

A few clouds with no new snow, northwest alpine winds 30 to 60 km/h, treeline temperatures around -16 °C.

Sunday

Mostly sunny with no new snow, northwest alpine winds 30 to 50 km/h, treeline temperatures -8 °C.

Monday

Mostly sunny with no new snow, variable alpine winds 10 to 20 km/h, treeline temperatures -8 °C.

Tuesday

Increasing cloud with no new snow, southwest alpine winds 30 to 40 km/h. An above-freezing layer brings warm air, treeline temperatures reach -4 °C.

• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Carefully evaluate steep lines for wind slabs.
