Avalanche danger will increase as storm snow piles up, and snowfall amounts could vary across the forecast area.

Avalanche Summary

No new avalanches have been reported but information is limited.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

By the end of of the day on Tuesday, above 1500 m, 20-30 cm of new snow should be covering another 20 cm of soft, settling snow. Below that, surface hoar crystals overlie faceted or wind-affected snow on northerly alpine terrain or a hard melt-freeze crust elsewhere.

Below 1500 m, expect a moist or wet snow surface due to rain.

A widespread crust that formed in early February is buried anywhere from 50 to 120 cm deep. This crust has a weak layer of faceted grains above it that are slowly strengthening. This layer is currently dormant.

Weather Summary

Monday Night

Cloudy. Light rain expected. 2-5 cm of snow above 1500 m. Light to moderate southwest ridgetop wind, possibly strong in the north end of the forecast area. Treeline temperature around 1 °C.

Tuesday

Cloudy. Moderate rain expected, 15-25 cm of snow above 1500 m. Light to moderate southwest ridgetop wind, possibly strong in the north end of the forecast area. 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 10-15 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.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.

Avalanche Problems

Storm Slabs

Recent snow may not be bonding well to a widespread, firm crust, or weak, feathery surface hoar and sugary facets on north facing slopes. Deeper deposits may be found in lee terrain features near ridges.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Rain and elevated freezing levels could make wet loose avalanches possible.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
