Two teenagers playing outside a home in Breckenridge, Colorado, were buried when a roof avalanche occurred, officials with the Colorado Avalanche Information Center (CAIC) reported Tuesday night.

Both teens were partially buried in the debris Monday, with one seriously injured.

“This is a tragic accident. Like any avalanche accident, we want to warn people about being caught in a similar event,” CAIC Director Ethan Greene said in a news release. “Roof avalanches are a problem every year in mountain communities, but right now we have a lot of snow in unusual places. We remain concerned about this hazard throughout the week.”

The CAIC said roof avalanches can seriously injure or kill people. Roof avalanches often release during a large snowstorm or when there is rapid warming following a big storm. CAIC recommends the following safety advice when a roof has a thick build-up of snow:

• Always pay attention to snowy roofs above you, and do not play with icicles.

• Minimize the amount of time you spend below snow-loaded roofs.

• Watch exposed people and keep a shovel nearby to locate someone.

• Shovel roofs early to reduce the snow load and potential consequences of larger roof avalanches.

The last roof avalanche fatality in Colorado occurred on March 16, 2023, near Durango when two children and a father were buried in a slide, and one child died. That accident report can be found here.

Five people have lost their lives in roof avalanches in Colorado in the last 30 years, and there have been many more injuries and close calls.
