Additionally, the Colorado Avalanche Information Center has broadcast an avalanche warning in effect for portions of the northern mountains of Colorado, including the Front Range mountains, all of Summit County and areas around Vail.

Avalanche danger is high, at a level 4 of 5 near and above tree line. Snowfall and strong westerly winds on Thursday will overload the weak snowpack and result in large natural avalanches in many areas. Backcountry travel is not recommended.

HIGH (4of5) Very dangerous avy conditions exist. Deep Persistent avy problem means avys are hard to predict, can break in surprising ways, can be triggered from below, will run to the ground, will kill you. Travel in avalanche terrain not recommended https://t.co/TfP7PWuk2j

OpenSnow.com meteorologist Joel Gratz said in his morning report that most of this weekend will be dry, and the next storm should bring snow to most mountains between Sunday night and Tuesday morning.

“And this active pattern will likely continue through at least the end of February,” Gratz writes.
