The Northwest Avalanche Center issued a special bulletin Saturday warning of “considerable” avalanche risk on Mount Hood, at least through Monday.

“The epic storm cycle that wrapped up Wednesday produced several deep avalanches averaging around 4 feet that were triggered Wednesday and Thursday by both skiers and explosives near and below treeline,” the avalanche center wrote in an advisory.

“The risk of tree well and snow immersion suffocation continues in areas with deep snow. Don't travel alone and always keep in contact with your partner,” the avalanche center warned. If the sun emerges Sunday, the center said those on the slopes or in the backcountry should “expect roller balls and loose wet activity that will entrain the surface snow and shed off rocks and steep slopes.”

The center warned that avalanche conditions are dangerous both above and below the treeline. The “considerable” risk rating is the third highest on a five-level scale.

"Even in lower elevation terrain below treeline, choose simple terrain, avoiding steep chutes or open slopes capable of producing a large avalanche,” the avalanche center advises.
