Avalanche Forecast

Low

No new avalanches were reported on Sunday. However, observations are very limited during this time of year and we expect large storm slabs to be reactive to human triggers.

Observations are very limited at this time of year, please consider sharing any information or photos you have on the Mountain Information Network to help guide our forecasts.

10-20 cm of new snow Monday morning brings recent storm snow to 30-45 cm (rain below 800 m). The recent snow and extreme southerly wind have formed large and reactive storm slabs.

At upper elevations, the recent snow is likely sitting on hard surfaces on windward aspects and settled old snow on northerly aspects. Below 1400 m, the recent snow is sitting on a crust on all aspects.

The middle and lower snowpack are strong and well-bonded.

Monday Night

Mostly cloudy with flurries; 5-15 cm / 30 km/h southeast ridgetop wind / Temperature at treeline around -3 C / Freezing level 500 m

Tuesday

Mix of sun and cloud with isolated flurries; 3-15 cm / 30 km/h southwest ridgetop wind / Temperature at treeline around -1 C / Freezing level 1000 m

Wednesday

Mix of sun and cloud with isolated flurries; 3-10 cm / 30 km/h south ridgetop wind / Temperature at treeline around -1 C / Freezing level 1000 m

Thursday

Mix of sun and cloud / 30 km/h south ridgetop wind / Temperature at treeline around 0 C / Freezing level 1100 m

• Conservative terrain selection is critical, choose only well supported, low consequence lines.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Avoid exposure to overhead avalanche terrain, avalanches may run surprisingly far.
• Avoid all avalanche terrain during periods of strong wind.
• Use small low consequence slopes to test the bond of the new snow.
