Conditions may evolve quickly at this time of year.

Be wary of loose wet avalanches on steep features, especially if solar radiation is strong.

Moderate

Avalanche Summary

No new avalanche was reported, but visibility restricted field observations. Large wet avalanches (up to size 2.5) were naturally triggered during the past storm cycle over the weekend and evidences are still visible around Mt Washington.

Snowpack Summary

30 cm of moist snow is overlying 20 cm of rain-soaked snowpack burying a strong melt-freeze crust. In the alpine, up to 50 cm of moist snow may be found. A sandwich of surface hoar and faceted snow from late January crust is now down 60 to 100 cm. At lower elevations, rain has soaked the snowpack. The lower snowpack is well-settled.

Weather Summary

Tuesday Night

Partly cloudy with isolated flurries. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -2°C. Freezing level around 1000 m.

Wednesday

Mix of sun and clouds. 50 to 70 km/h south west ridgetop wind. Treeline temperature +5°C. Freezing level reaching 2500 m.

Thursday

5 to 10 cm of wet snow or rain. 40 to 50 km/h southwesterly ridgetop wind. Treeline temperature +3°C. Freezing level around 2000 m.

Friday

Cloudy with isolated flurries. 25 to 45 km/h southwest ridgetop wind. Treeline temperature +5°C. Freezing level reaching 2500 m.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Avalanche Problems

Loose Wet

Surface snow may produce loose wet avalanches in steep terrain, particularly if the solar radiation is strong. Surface crust formation, where it occurs, will neutralize this problem.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
