A big storm is forecast, bringing significant rain amounts and strong winds that will make travel challenging.
Watch for changing conditions with elevation.
Storm slabs may be forming at the highest elevations in the region before snow turns to rain in the afternoon. These slabs will be most reactive during their formation and on leeward slopes due to strong winds.
Significant rain and high freezing levels may saturate the snowpack, making wet loose avalanches possible.
No recent avalanches have been reported. However, observations are extremely limited in this area.
If you're heading out into the backcountry, please consider sharing your observations on the MIN.
Up to 70 mm of rain is expected to fall overnight and through Monday. The highest elevations may see some snow falling at times, but freezing levels are expected to rise above mountain tops by Monday afternoon. This will saturate and considerably melt the current snowpack, which diminishes rapidly as you lose elevation. Currently, treeline elevation is estimated to have between 30 to 80 cm of snow.
