Avalanche Forecast

Moderate

No recent avalanche activity has been reported.

However, we anticipate a widespread avalanche cycle to take place Thursday night, into Friday during stormy weather conditions.

New snow continues to accumulate over a variety of wind-affected surfaces, faceted crystals, and surface hoar, all of which could prolong the bonding time between new snow and buried surfaces.

Continued snow or rain and warming temperatures will likely result in an upside-down upper snowpack by the end of the day on Friday.

The mid and lower snowpack is generally settled and well-bonded.

Thursday Night

Cloudy with 10 to 20 cm of snow, south alpine winds 30 to 50 km/h, treeline temperature -2 °C.

Friday

Cloudy with 20 to 40 mm of rain at lower elevations and wet snow at higher elevations, south alpine winds 30 to 50 km/h, treeline temperature +2 °C. Freezing levels around 2000 m.

Saturday

Cloudy with trace amounts of rain or wet snow, southwest alpine winds 20 to 40 km/h, treeline temperature +4 °C. Freezing levels around 2200 m.

Sunday

Cloudy with trace amounts of rain or wet snow, south alpine winds 30 to 50 km/h, treeline temperature 0 °C. Freezing levels around 1500 m.

• Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Watch for rapidly changing conditions during periods of heavy loading from new snow, wind, or rain.
• Storm slab size and sensitivity to triggering will likely increase through the day.
