You can trigger a large avalanche in recently drifted snow. These avalanches can step down to the ground and grow even larger. Suspect slopes will look pillowy and firm and may crack under your weight. You will find these areas below ridgelines and along gullies. Shallow slopes with exposed rocks and trees are where you are most likely to find a weak area and trigger a deeper avalanche. You will not get any warning signs, and multiple people could ride a slope before you find a weak area. You can find safer riding on slopes less than about 30 degrees.
Sunny skies and above-freezing temperatures tomorrow will likely cause the snow to become wet and sluff off steep, sunny slopes. These avalanches could gouge deeper into the snowpack and grow larger as they run. If you sink up to your ankles in wet, gloppy surface snow or see rollerballs, you should steer clear of steep slopes.
