South Coast

Expect storm slabs to be much more reactive at upper elevations where the snow remains dry.

Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.

Moderate

• We are uncertain due to variable freezing levels.

Large, natural avalanches are expected to occur in the alpine on Friday.

Wet loose avalanches may occur at treeline and below.

20 to 30 cm of forecast snow above 1300 m and strong south wind will form reactive storm slabs at upper elevations on Friday.

The recent snow overlies a hard crust in most locations.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 70 to 175 cm at treeline elevations.

• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.
• Be alert to conditions that change with aspect and elevation.
• Use small, low consequence slopes to test the bond of the new snow.
