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.
