A powerful winter storm will rapidly increase the danger throughout the day. Slopes that were safe in the morning may not be by afternoon. You can trigger an avalanche in drifted snow at upper elevations. Avoid rounded pillows of drifted snow on steep slopes below ridges, in gullies, and behind convex rollovers. These may be firm underfoot and can crack when weighted. Avoiding these pillows and seeking out sheltered or lower-angled slopes are ways to reduce your hazard.
