Use safe travel habits, and constantly assess conditions as you travel.
Both rain and snow are expected. The sun should be less intense, but freezing levels remain elevated.

Avalanche Summary
No new avalanches have been reported.
Please consider submitting your observations to the MIN if you head to the backcountry.
Snowpack Summary
By the end of the day on Tuesday, above 1700 m, expect 25-50 cm of soft snow on the surface. Under this, weak, feathery surface hoar crystals sit on faceted or wind-affected snow on northerly alpine terrain and a hard melt-freeze crust elsewhere.
Below 1700 m, expect the snow surface to be moist due to light rain.
A widespread crust that formed in early February is buried anywhere from 80 to 150 cm deep. This crust has a weak layer of faceted grains above it that are slowly strengthening. This layer is currently dormant.
The remainder of the snowpack is settled.
Weather Summary
Monday Night
Cloudy. Light rain expected. 0-2 cm of snow above 1700 m. Light to moderate southwest ridgetop wind. Treeline temperature around 1 °C.
Tuesday
Cloudy. Light rain expected, 5-10 cm of snow above 1700 m. Light to moderate southwest ridgetop wind. Treeline temperature around 1 °C.
Wednesday
Mostly cloudy. Light to moderate precipitation continues as the freezing level drops to valley bottom. It could add up to 15-20 cm of snow at high elevations. Light to moderate southwest ridgetop wind. Treeline temperature around -5 °C.
Thursday
Mostly cloudy. No new snow expected. Light northeast ridgetop wind. Treeline high around -5 °C.

Terrain and Travel Advice
- Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
Problems
Storm Slabs
Recently formed storm slabs may not bond well to underlying layers, including weak surface hoar or facets on northerly terrain, and a hard melt-freeze crust elsewhere. Deeper deposits may be found in lee terrain features near ridges.
