General Advisory

GENERAL AVALANCHE ADVISORY Warmer air is beginning to move in aloft. Temperatures at 10,500 feet at 5 AM this morning are 10 to 15 degrees warmer than they were at the same time yesterday morning. Human triggered avalanches continue to be a hazard in steep terrain. Surface slabs could be triggered by skiers or riders who venture into steep wind loaded avalanche starting zones, cliff areas and steep couloirs. Deep persistent slabs which have been a potential problem at the upper elevations since early December are unlikely.

Situation

SITUATION A high pressure ridge is positioned over the region. Conditions remain dry with strong temperature inversions. In the mountains temperatures warmed into the teens and 20s from overnight lows in the single digits and teens. Valley temperatures rose in the single digits above zero from overnight lows that ranged from ten to thirty degrees below zero. Winds were northerly at 5 to 20 miles per hour. Surface hoar growth continues. Sun crust development also continues. Snowpack settlement continues. Twenty four hour settlement rates have decreased to around an inch a day.

FORECAST FOR Tuesday, January 17, 2017 Conditions will remain mostly unchanged. Similar temperatures will occur. Skies will be mostly clear. Winds will back towards the west. The general avalanche hazard is expected to be MODERATE. Surface slabs up to two feet deep could be human triggered in steep avalanche starting zones, steep couloirs and cliff areas. Deep persistent slabs are still a potential hazard with severe consequences at the upper elevations in the Greys River and Togwotee Pass areas.

TREND FOR Wednesday, January 18, 2017 AND Thursday, January 19, 2017 Dry conditions will continue. Warmer air will begin to move into the region on Wednesday. The general avalanche hazard will continue to slowly decrease.
