Regions

South Coast.

Keep a close eye on how the temperature and sun are affecting the snowpack in your local zone. The freezing level is forecasted to rise well into the alpine for Tuesday morning, but other factors may keep the upper snowpack cool, lowering avalanche danger. 

Confidence

Moderate - Uncertainty is due to how the snowpack will react to the forecast weather. A small change in the upper snowpack could dramatically change avalanche conditions.

Weather Forecast

MONDAY NIGHT: Partly cloudy, possible clearing through the night. No new snow/rain expected. Light northeast ridgetop wind. Freezing level around 2000 m.

TUESDAY: Mostly sunny, with possible valley cloud. No new snow/rain expected. Light variable wind. Freezing level rises to around 2600 m. 

WEDNESDAY: Partly cloudy. Up to 10 cm of snow is possible at high elevations overnight and through the day. Light to moderate west riddetop wind. Freezing level falling to around 1100 m. 

THURSDAY: Mostly sunny. Very light snow/rain expected. Light northwest ridgetop wind. Freezing level around 750 m overnight, rising to 1200 m through the day.  

Avalanche Summary

Several small loose wet avalanches have been naturally triggered in the last few days by warm temperatures, short periods of sunshine, and rain. 

If you venture into the mountains, please share any observations on the Mountain Information Network. 

Snowpack Summary

Moist snow or a melt freeze crust likely exists to mountain top. The crust may break down as temperatures rise, and on south facing slopes as the sun pokes out.

The upper snowpack consists of hard wind pressed surfaces and a series crusts. 

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

Terrain and Travel

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Make observations and assess conditions continually as you travel.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
