A search is being conducted in northern Colorado for a Marlton man who is reported missing after he planned to climb Longs Peak in Rocky Mountain National Park.

According to park officials, rangers were contacted by Denver police who had been notified by a family member that Ryan Albert, 30, of Marlton, was overdue from a planned climb on Thursday.

Albert's rental car was found Friday afternoon at the Longs Peak trailhead.

Park officials say Albert's planned destination or route was unknown.

The weather forecast on Saturday for the Longs Peak area called for freezing temperatures and severe and unpredictable weather including snow, hail, sleet, thunder and lightning.
