Highlights
The backcountry is transitioning, heavy wet snow on the uppers and draining (rain soaked) from mid-elevations. Wind-slab conditions in start zones. Combine this with wet unsupportive snow at mid/low elevations.
Avalanche problems
Recent Avalanche Activity
No recent activity reported. Lots of snow transport yesterday.
Current Snowpack Conditions
The front moved through yesterday with several pulses. One would arrive with rain the next one snow. Fluctuation in the freezing level obvious with heavy wet snow the result. Wind-slab conditions in start zones and around terrain features are possible. Rain on snow will continue again today. At lower elevations a rotten (isothermic) pack. Coverage is still thin, we are seeing a good base develop. Many hidden hazards sit just below a thin coverage. Fair to say backcountry observations have been limited for several days.
Mountain Weather
Snow showers continuing with the occasional heavy burst. Perhaps the odd glimpse of sun in-between rolling pulses. Gale NW winds, turn W late in the day. The freezing level around 1400 m.
Sliding Danger
Once frosts return we will see slick conditions develop.
Forecast Confidence
Moderate
- We are uncertain due to a limited number of field observations.
