Long Range Mountains

New snow and wind will create dangerous conditions on steep wind-loaded slopes.

A few small (size 1) wind slab avalanches were observed over the past few days. Wind slabs will grow and become larger and more reactive over the weekend.

10 to 20 cm of new snow by Saturday morning is adding to 20 to 40 cm from the past week. This recent snow has accumulated above a widespread crust layer.

Extreme southwest wind will scour windward slopes and form deep deposits on lee terrain features.

Many parts of the region have low snow coverage and lower elevation terrain is likely thin and rocky.

Friday Night

Flurries with 10 to 20 cm of snow. 80 km/h southwest wind. Mountain temperatures -4 °C.

Saturday

Cloudy with a trace of snow. 60 km/h southwest wind. Mountain temperatures -5 °C.

• 15 to 25 cm of snow in the Northern Peninsula.

100 km/h southwest wind. Freezing level rises to 2000 m in the south, 1000 m in Gros Morne, and sea level in the north.

Mix of sun and cloud. 25 km/h north wind. Mountain temperatures -6 °C.

• Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
• Use ridges or ribs to avoid areas of wind loaded snow.
