Storm slabs will be more reactive at or near ridge crests on north through east faces where wind deposited snow will be thicker.
Start on small slopes, and check for signs of instability before committing to steep or high-consequence terrain.
Riding conditions and avalanche problems will change with elevation.
Storm slabs will be more reactive at or near ridge crests on north through east faces where wind deposited snow will be thicker.
Use caution when encountering moist or wet snow in steep areas or gullies.
On Sunday, numerous large (up to size 2) naturally triggered avalanches were reported across the forecast area in steep, north and east-facing alpine terrain.
Looking ahead to Tuesday, we expect that natural avalanches will be less likely, but human-triggered avalanches will remain possible.
Freezing levels drop and 10 -15 cm of new snow is expected in the alpine. Treeline will see shallower, denser snow, and rain continues below treeline. This falls on a mostly moist or wet upper snowpack. except for high alpine elevations where deeper dry snow may still be found.
Storm snow amounts over the last week have varied across the region, generally 25-40 cm. On north and east faces storm slabs may be thicker due to recent winds. The storm snow may be poorly bonded to a crust formed in early January that extends up to treeline elevations.
Two deeper surface hoar layers exist. These layers have become dormant and unlikely to trigger.
Monday Night
Cloudy. 10-15 cm of snow expected above 1250 m. Moderate southeast ridgetop wind trending to strong southwest by the morning. Treeline temperature around 0 °C.
Tuesday
Cloudy. Trace of snow above 1250 m. Strong to extreme southwest ridgetop wind. Treeline temperature around 0°C.
Wednesday
Cloudy. Light snow in the morning turning to light rain below 1750 m in the afternoon. Strong southeast ridgetop wind. Treeline temperature around 2 °C.
Thursday
Mostly cloudy. 5 cm of snow expected above 1500 m. Moderate south or southeast ridgetop wind. Treeline temperature around 1 °C.
