Fresh wind slabs are likely along ridgelines and in alpine terrain.

While direct observations are lacking, recent storms likely produced wind slab and wet loose activity. As temperatures cool on Friday, wind slabs at upper elevations will be the main concern.

Up to 20 cm of new snow is possible in higher terrain Thursday night, likely to be heavily wind-affected. Amounts will taper off quickly below treeline, though the exact rain-snow line remains uncertain.

The new snow is expected to bond well to an otherwise strong and well-settled snowpack.

Lower elevations are melting out rapidly.

Thursday Night

Cloudy with 10 to 20 cm of snow above 1200 m. 60 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level drops from 2000 to 1200 m.

Friday

Cloudy with 0 to 4 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1500 m.

Saturday

Mix of sun and cloud with 5 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -5 °C. Freezing level 1300 m.

• Be especially cautious as you transition into wind-affected terrain.
• Dial back your terrain choices if you are seeing more than 20 cm of new snow.
• A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
