The weather for this storm is uncertain, so you may have to do some detective work out in the field. If this makes you uncomfortable, stick to low-angle slopes. The most dangerous slopes are where variable winds will drift snow onto a variety of aspects and into unusual locations. Look for and avoid rounded pillows of snow that may be firm or soft. These slabs will build and change during the day and may be found in open areas below the treeline. You can find safer riding on sheltered slopes.
Buried weak layers lurk two to four feet deep on northerly-facing terrain at upper elevations. In areas with the deepest snowfall accumulations, these layers may become more sensitive. To reduce your chances of triggering a deeper slide avoid steep slopes with a thinner-than-average snowpack, where it is easier to trigger a large and destructive avalanche.
