Freezing levels should drop enough for some new snow to fall in the alpine and possibly at treeline. Expect any fresh accumulations to become unstable when the pendulum swings back to rain.
Any fresh snow that accumulates at higher elevations will become unstable as flurries transition to rain once again. Steep features holding more snow, such as couloirs and gullies, will be most likely to produce small wet loose sluffs.
No recent avalanches have been reported. Observations are limited in this area, but so is the snowpack.
If you head out into the backcountry, please consider sharing your observations on the MIN.
A mix of snow followed by heavy rain will do little to improve snowpack coverage by end of day Tuesday. High alpine locations may see 10 -15 cm accumulate before it is again affected by rain.
Before the storm, higher treeline areas held an estimated 20 to 50 cm of snow. This diminishes rapidly below 1500 m.
Monday Night
Cloudy with light flurries bringing 4 to 10 cm of new snow. 40 - 60 km/h southwest ridgetop wind. Treeline temperature 0 to -1 °C. Freezing level 1100 - 1300 m.
Tuesday
Cloudy. 20 to 30 mm of precipitation, first as snow, increasingly as rain at treeline. More snow again overnight. 20 - 60 km/h south ridgetop wind. Treeline temperature -1 to 1 °C. Freezing level 1300 - 1600 m.
Wednesday
Mostly cloudy with scattered flurries after 20 to 30 cm of snow overnight. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.
Thursday
Cloudy with 20 to 50 cm of new snow, including overnight amounts, rain during midday. 60 km/h south ridgetop wind. Treeline temperature -3 °C to 1 °C. Freezing level rising to 1500 m before returning to 1100 m.
