Kernpunkte

Rapid loading and strong winds are creating dangerous avalanche conditions in mid and upper elevation avalanche starting zones. The hazard will be increasing as the day progresses. Human triggered avalanches are likely and natural triggered avalanches are possible and could run long distances. Expert terrain evaluation and route finding skills are essential for safe travel in avalanche terrain.

    South-southwest to west winds are building dense new slabs on leeward aspects. These slabs are forming on slick old snow surfaces and are likely to be easily triggered by humans. As the day progresses and these slabs gain depth and volume natural releases are possible, especially at the upper elevations. These slides could have crown depths to two feet and run long distances into the lower elevations.

    Weak snow persists near the ground. In isolated areas, skiers and riders might be able to trigger dangerous hard slabs with depths to 40 inches failing on this weak layer. This basal weakness is limited in distribution and is most likely to be found along the east slope of the Wyoming Range.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )A potent low pressure system will move inland and bring periods of heavy snowfall and strong winds to the mountains. Snowfall totals of 7 to 14 inches are possible at the higher elevations by Monday evening. Strong southwest to west winds with average speeds of 25 to 35 and gusts to 50 miles per hour will accompany this snowfall. Temperatures will remain in the 20s in the mountains. Periods of rain and snow may continue at the lower elevations where the freezing level is expected to drop to the valley levels overnight and rise to 7,800 feet in the afternoon.In the mountains the hazard will increase overnight and during the day. Strong winds will create new wind slabs on leeward aspects. These slabs are expected to grow to depths of two feet in upper elevation avalanche starting zones and be sensitive to human triggers. The general avalanche hazard is expected to increase to MODERATE by morning and may increase to CONSIDERABLE at the upper elevations during the day if periods of high intensity snowfall are sustained. Natural avalanche activity may become possible.
