South Coast

A significant jump in freezing levels combined with rain is going to increase hazard.

Avoid avalanche terrain and be prepared to change your plans if you see rain falling on dry snow.

The snow is getting rain-soaked to mountain top, when the freezing levels starting to drop we expect a surface crust to form. Much of the snowpack is likely becoming isothermal.

The mid and lower snowpack are generally strong and well-bonded.

Typical treeline snow depths range from 100 to 150 cm, and thins quickly below treeline, especially on south-facing slopes.

Moderate

• We are uncertain if precipitation will fall as rain or snow.
• We are confident the likelihood of avalanches will increase with the forecast weather.
• We are confident the snowpack will rapidly weaken with the forecast weather.

No recent avalanche activity has been reported, however we expect that the warm temperatures and high freezing levels have caused a loose wet cycle.

If you head out, please consider posting your observations to the Mountain Information Network.

• The first few hours of rain will likely be the most dangerous period.
• Avalanche danger will rapidly increase if snow switches to rain.
• Avoid avalanche terrain during periods of heavy rain.
