GRAND JUNCTION, Colo. (KKCO) -- Unfavorable weather conditions caused the Wild Fork Complex wildfires in southern Colorado to spread rapidly overnight, growing to 108 square miles.
The colossal fire has now consumed 70-thousand acres.
The blaze started June 5th from a lightening strike, but its quick advance has prompted hundreds of visitors and the town's 400 residents to evacuate.
More than 400 firefighters are working to control the fire, and more are on their way.
The fire remains zero percent contained and authorities say it has high growth potential, since strong winds are making the blaze unpredictable and hard to battle.
