Weather Forecast
FRIDAY NIGHT: Cloudy with snowfall, accumulation of 20 to 30 cm, moderate southwest wind, treeline temperature -4 C, freezing level at 1000 m.
SATURDAY: Cloudy with sunny periods, moderate northwest wind, treeline temperature -3 C, freezing level dropping to 500 m.

Avalanche Summary
On Thursday, no new avalanches were reported.
On Wednesday, a few natural wet loose avalanches up to size 1.5 were observed.
Storm slabs were reactive to human traffic on Monday. It is likely that a natural avalanche cycle occurred Monday night as the snow switched to rain.
Snowpack Summary
Overnight 20 to 30 cm of snow is expected by Saturday morning down to an elevation of about 1000 m adding to the snow received on Friday. Most precipitation of the previous storm on Tuesday fell as rain below about 1500 m.
There is uncertainty how well the new snow will bond with the old snow surface. Assess the bond of the recent snow before committing to avalanche terrain and travel conservatively.
Terrain and Travel
- Make observations and assess conditions continually as you travel.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Travel in alpine terrain is not recommended.
