We expect avalanche activity to continue with rain-on-snow and warming. No new avalanche reports on Monday.

On Sunday several storm slab avalanches were reported, size 1 and 2. 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.

5 to 15 mm of rain is expected to fall up to 2500 m. This falls on up to 50 cm of recent snow redistributed by southwest winds at upper elevations, and an already moist snowpack at lower elevations.

This overlies up to 1.5 m 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.

Tuesday Night

Clear with some clouds. 15 to 45 km/h south ridgetop winds. Treeline temperature 10 °C. Freezing level 3000 m.

Wednesday

Mostly cloudy with rain 15 to 20 mm. 15 to 35 km/h south ridgetop winds. Treeline temperature 10 °C. Freezing level rises to 3000 m.

Thursday

Rain, 10 to 25 mm falling as snow above 1200 m. 30 to 50 km/h southeast ridgetop winds. Treeline temperature 2 °C.

Friday

Cloudy with 15 to 30 mm, falling as snow above 1200 m. 15 gusting to 60 km/h south ridgetop winds. Treeline temperature 3 °C.

On Tuesday, numerous natural and explosive triggered wet slab avalanches were reported up to size 3.

On Monday, numerous large slab avalanches were seen up to size 2.5.

We expect avalanche activity to continue with both wet and large slab avalanches being easy to trigger during this warm period.

We have received up to 30 mm of recent precipitation; snow above 1500 m and rain below this elevation. Expect deeper and more reactive deposits on north—and east-facing slopes. This overlies 40 cm of recent snow. Expect to find rain-soaked or moist snow below 1500 m.

This overlies 50 cm of settled 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.

Tuesday Night

Cloudy. 15 to 45 km/h south ridgetop winds. Treeline temperature 6 °C. Freezing level 2500 m.

Wednesday

Mostly cloudy with sunny periods and light rain 5 mm. 15 to 35 km/h south ridgetop winds. Treeline temperature 9 °C. Freezing level rises to 3000 m.

Thursday

Wet flurries 5 to 10 cm above 1500 m falling as rain below. 15 to 35 km/h southeast ridgetop winds. Treeline temperature 2 °C.

Friday

Cloudy with a mix of rain and snow 10 to 15 cm. 15 gusting to 60 km/h south ridgetop winds. Treeline temperature 2 °C. Freezing level 1600 m.

On Monday, numerous natural wet loose avalanches up to size 2 were reported in the southern part of the region. Check out this MIN report for more details.

We expect a natural avalanche cycle to continue with rain and warm temperatures destabilizing the snowpack.

Thank you for sharing your observations to the MIN.

10 mm of rain is expected to create moist surfaces on all aspects and elevations. This falls on 40 to 60 cm of settling storm snow which was redistributed into deeper deposits on north- and east-facing slopes by strong southwest winds. This sits atop 80 to 100 cm of settled snow on north-facing slopes, and several thin melt-freeze layers on south-facing slopes.

A supportive crust is found below this, on all aspects except on high, north-facing alpine terrain. Snow is reportedly bonded well to it.

A weak layer of facets and surface hoar from February is now 90 to 150 cm deep and a layer of facets and surface hoar from late January is 110 to 190 cm deep. Some recent planar results were reported in the Manning Park area.

Tuesday Night

Cloudy. 15 to 45 km/h south ridgetop winds. Treeline temperature 5 °C. Freezing level 1300 m.

Wednesday

Mostly cloudy with light rain. 15 to 20 km/h south ridgetop winds. Treeline temperature 10 °C. Freezing level rises to 3200 m.

Thursday

Cloudy with wet snow 5 to 10 cm above 1800 m. 15 to 50 km/h south ridgetop winds. Treeline temperature 4 °C.

Friday

Cloudy with snow 5 to 10 cm above 1500 m. 15 gusting to 65 km/h southeast ridgetop winds. Treeline temperature 4 °C.
