General Advisory

GENERAL AVALANCHE ADVISORY Deep instabilities continue to be a concern on steep avalanche prone slopes at the mid and upper elevations. Snowmobiles and skiers could still trigger dangerous hard slab avalanches. Wind slabs that formed during the last storm cycle may still be able to be triggered by the weight of a person in very steep avalanche starting zones and cliff areas. Avalanches are unlikely at the lower elevations.

Situation

SITUATION Western Wyoming remains under the influence of a broad trough. Skies were mostly cloudy today with some snow flurries over the mountains. Temperatures at an elevation of 9,000 feet were mostly in the single digits above and below zero. The coldest temperatures were to be found along and east of the Continental Divide where it remained below zero all day. The lower elevations were mostly in the teens. Winds were light at 5 to 15 miles per hour. The snow that fell over the weekend continues to settle and gain stability. Instabilities associated with deeply buried layers of faceted snow persist.

FORECAST FOR Tuesday, February 20, 2018 A northerly flow will continue to bring arctic air into the area. Skies will continue to be partly to mostly cloudy with a chance of snow flurries or periods of very light snowfall over the mountains. Temperatures are forecast to be below zero overnight and rise into the single digits during the day. Winds will be light from the northwest to west. Deep instabilities continue to be a concern on steep avalanche prone slopes above an elevation of 7,500 feet. Some potential persist for snowmobiles and skiers to trigger dangerous hard slab avalanches up to five feet in depth. Hazards associated with wind slabs that formed during the last storm cycle may linger in very steep avalanche starting zones and cliff areas. The general avalanche hazard is expected to be MODERATE at the mid and upper elevations (7,500 to 10,500 feet) and LOW below those elevations.

TREND FOR Wednesday, February 21, 2018 AND Thursday, February 22, 2018 Temperatures will continue to be well below normal. The general avalanche hazard is suspected to be on a slow decreasing trend
