    Wet loose avalanches are possible where the forecasted precipitation falls as rain.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.
  • We are confident the likelihood of avalanches will increase with the forecast weather.

Avalanche Summary

No avalanches have been reported recently. Avalanche activity will increase with the forecasted weather.

If you get out into the backcountry, post a MIN!

Snowpack Summary

20 to 45 mm of precipitation is expected by the end of the forecast period on Tuesday, with the highest amounts in the western part of the region. Freezing levels will be around 1000 m, which means the mountains will receive a hefty dose of fresh snow. This new snow falls on a melt-freeze crust, moist snow, or isothermal conditions, depending on aspect and elevation.

Little change is expected at lower elevations. Watch for slushy, isothermal conditions—these can make travel difficult and increase the likelihood of wet loose avalanches.
