WINTERSPORTS -- Backcountry winter travel basics tell us that heavy snowfall followed by significant warming results in increased avalanche danger for snowgoers.

The last Idaho Panhandle Avalanche Center forecast was Jan. 2, when conditions were relatively stable and the avalanche danger was rated at Level 2.

The conditions changed dramatically on Sunday and Monday, but the avalanche center won't issue another advisory until Friday, Jan. 9.

Be careful in the the gap.

Boise National Forest officials are cautioning backcountry skiers and snowmobilers to be extra careful in the mountains over the next few days because of recent avalanche evidence.  Similar advice is coming from throughout the region.

Locations that received significant snowfall will pose an increased risk of human-triggered avalanches for several days while the new snow settles and bonds with the existing snow pack, officials said.

Backcountry skiers and snowmobilers should always carry avalanche rescue gear when traveling on or adjacent to steep slopes
