Colorado's deadly avalanche streak prompts new backcountry warning

• A weak layer of early-season snow, followed by heavy recent snowfalls, is creating more frequent and larger avalanches.
• "We looked at the calendar and said, 'We don't want a fourth accident,'" the center's director, Ethan Greene, told John.

By the numbers: Since Dec. 16, the center recorded 870 avalanches, far more than typical for the early season.

• At least nine people have been caught in slides. Four people have died — two snowmobilers and two skiers.

Be smart: The state's avalanche forecast map is not at its highest level, but Greene said conditions are not as stable in many areas as they seem. The usual dangerous signs are not visible in many areas, and backcountry travelers are remotely triggering slides hundreds of feet away.

• "We need to get over this hump. The best way to do that is give the snowpack a break," he said.
