Dangerous avalanche conditions will develop this weekend across the high country, prompting the Colorado Avalanche Information Center to issue a special avalanche advisory on Wednesday. The current avalanche danger is rated “considerable,” which is Level 3 on the CAIC’s 1-5 scale, for nearly every region of the mountains. CAIC forecasters expect it to worsen this weekend, prompting the advisory. The most dangerous avalanche conditions are likely to develop Saturday afternoon and into Sunday, the advisory said. “We’re getting continued snowfall, and we’re going to see a pretty big wind event on Friday,” CAIC director Ethan Greene said Thursday.
