During periods of high hazard, avoid all avalanche terrain.
We expect a large natural avalanche cycle with significant precipitation, warming and buried weak layers.

Terrain and Travel Advice:
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
  • Use extra caution for areas that are experiencing rapidly warming temperatures for the first time.
Storm Slab

Storm snow and moderate southwest winds will form touchy storm slabs. Expect to find deeper and more reactive deposits on north- and east-facing slopes at upper elevations, where the wind will load lee slopes.

Persistent Slab

A weak layer from early March is now 150 to 230 cm deep with January and February layers buried 200 to 300 cm. These weak layers remain a concern, especially in northerly alpine terrain.

Wet Loose

Rain-on-snow and warm temperatures will rapidly destabilize the snowpack, with 1750 m freezing levels and up to 20 mm expected.

Avalanche Summary

We expect a large natural avalanche cycle to continue with significant snowfall and strong winds, followed by rain at lower elevations.

On Saturday near Whistler, a natural cornice fall triggered a size 3 slab on the slope below.

Numerous human-triggered size 1.5 storm slabs, like this one, occurred in the alpine and upper treeline.

On Friday, an explosive-triggered size 2 storm slab was reported on the early March melt-freeze crust, on an east-facing slope in the alpine.

Snowpack Summary

Up to 20 mm of precipitation is expected by Monday's end; snow above 1500 m and rain below this elevation. This overlies the 40 cm of snow from Sunday. Expect deeper and more reactive deposits on north—and east-facing slopes. Expect to find rain-soaked, moist snow below 1500 m.

This overlies 50 cm of recent snow and then a melt-freeze crust on southerly slopes and at lower elevations.

A weak layer formed in early March found down 150 to 230 cm, consists of a crust on all aspects except high north-facing slopes. In some areas, a layer of surface hoar is found just above the crust.

Weak layers formed in mid-February and late January are now buried 200 to 300 cm deep.

Below this, the snowpack is well-settled and strong.

Weather Summary

Sunday Night

Cloudy with up to 15 mm, falling as snow above 1500 m. 40 to 50 km/h south ridgetop winds. Treeline temperature 1 °C.

Monday

Cloudy with 15 to 20 mm, falling as snow above 1500 m. 25 to 45 km/h southwest ridgetop winds. Treeline temperature 1 °C.

Tuesday

Cloudy with 15 to 20 mm, falling as snow above 2500 m. 30 to 50 km/h southwest ridgetop winds. Treeline temperature 4 °C.

Wednesday

Mostly cloudy with trace precipitation. 40 km/h southeast ridgetop winds. Treeline temperature 5 °C.

More details can be found in the Mountain Weather Forecast.

Confidence: moderate
Uncertainty is due to the complexity of the snowpack’s structure.
We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.

Wet Loose

Rain-on-snow and warm temperatures will rapidly destabilize the snowpack, with 2000 m freezing levels and up to 30 mm expected.

Avalanche Summary

Looking ahead, we expect a large natural avalanche cycle to continue with snowfall and extreme winds, followed by rain-on-snow and warming.

On Saturday at Grouse Mountain, numerous size 2 storm slabs were triggered remotely, up to 50 cm deep.

Thanks for sharing your observations to the MIN.

Snowpack Summary

Up to 60 mm of precipitation is expected by Monday's end, falling as snow above 1600 m and as rain below this elevation. This is in addition to the 50 cm of snow from Sunday. Throughout this stormy period, winds have been from the southwest, so expect deeper and more reactive deposits on north—and east-facing slopes. Expect to find rain-soaked, moist snow below 1600 m.

This overlies up to a meter of previous settling storm snow, which was reportedly well-bonded to an underlying, supportive crust, that is now expected to be 180 to 250 cm deep.

Below this, the snowpack is well-settled and strong.

See this North Shore SAR report for additional information.

Weather Summary

Sunday Night

Cloudy with up to 25 mm, falling as snow above 1500 m. Locally greater amounts are possible near Seymour. 40 to 60 km/h southwest ridgetop winds. Treeline temperature 2 °C.

Monday

Cloudy with 20 to 35 mm, falling as snow above 1600 m. 40 to 60 km/h southwest ridgetop winds. Treeline temperature 3 °C.

Tuesday

In the overnight period, 15 to 20 mm falling as snow above 2000 m.

Cloudy with up to 10 mm, falling as snow above 2500 m. 30 to 50 km/h southwest ridgetop wind. Treeline temperature 8 °C.

Wednesday

Mostly cloudy with trace precipitation amounts. 50 km/h southeast ridgetop winds. Treeline temperature 8 °C.

Confidence: high
The snowpack structure is generally well understood.

Avoid all avalanche terrain during periods of high hazard.
Many close calls occurred this week, and very large avalanches are expected to continue.

Terrain and Travel Advice:
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Be mindful that deep instabilities are still present and have produced recent large avalanches.
  • Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
Storm Slab

Storm snow and strong southwest winds will form touchy storm slabs. Expect to find deeper and more reactive deposits on north- and east-facing slopes.

Storm slabs may step-down to deeper layers resulting in very large avalanches.

Persistent Slab

Weak layers remain a concern, especially in north-facing terrain where snowpack depth is variable. Avoid steep and shallow rocky features where human-triggering is possible.

Wet Loose

Rain-on-snow and warm temperatures will rapidly destabilize the snowpack, with 1750 m freezing levels and up to 30 mm expected.

Avalanche Summary

Saturday, a very large avalanche was snowmobile triggered near Wendy Thompson.

Friday, skiers remotely triggered this very large avalanche near Vantage Peak. Explosive control produced four size 2.5 persistent slab avalanches on northwest alpine slopes.

Monday 18th, two very large persistent slabs were remotely triggered in the Birkenhead area. They occurred on west and east alpine slopes 75 to 100 cm deep, and one of them stepped down to the mid-February week layer.

Snowpack Summary

25 to 40 mm of new snow is expected, falling as rain below 1500m. Snow will be redistributed into deeper, more reactive deposits on north- and east-facing slopes by moderate to strong southwesterly winds.

A melt-freeze crust on southerly slopes up to 2000 m exists about 60 cm deep. This sits over 80 to 150 cm of settled snow.

The early March weak layer of facets or surface hoar on a crust is now down 100 to 170 cm and is present on all aspects except high north-facing slopes. Very large avalanches (size 3 to 3.5) were reported on this layer this past week.

Weak layers formed in mid-February and late-January are now buried 180 to 250 cm deep.

Weather Summary

Sunday Night

Cloudy with 5 to 10 mm, falling as snow above 1400 m. 30 to 60 km/h southwest ridgetop winds. Treeline temperature -2 °C.

Monday

Cloudy with 10 to 20 mm, falling as snow above 1500 m. 20 to 40 km/h southwest ridgetop winds. Treeline temperature -1 °C.

Tuesday

Cloudy with trace precipitation. 30 km/h south ridgetop winds. Treeline temperature 3 °C.

Wednesday

Cloudy with trace precipitation. 30 km/h south ridgetop winds. Treeline temperature 4 °C.

More details can be found in the Mountain Weather Forecast.

Confidence: moderate
Uncertainty is due to the fact that persistent slabs are particularly difficult to forecast.
We are confident the likelihood of avalanche will increase with the arrival of the forecast weather.
