The Whittier Fire, currently the third-largest wildfire, barreled over more than 5,000 acres, engulfing mountain peaks within the Los Padres National Forest.

Flames and smoke temporarily prevented some 80 people -- mostly children -- from being evacuated from their campsite on Saturday, authorities said.

The blaze "has real potential for growth" because the area hasn't burned in around seven decades, Andrew Madsen, the national forest public affairs officer, told NBC News.

Wildfires are scorching California even as the state recovers from five years of severe drought.

Record rainfall and snowpack in parts of the state earlier this year delayed the state of the wildfire season in some places. But it also led to explosive growth of vegetation, which could fuel future fires, the Associated Press noted.

While blazes are often sparked by careless campers or arsonists, they're also striking more frequently, and burning for longer periods of time, due in part to human-caused climate change.

As average temperatures rise, heat waves strike and rainfall disappears, the soil and plants are drying out faster, raising the long-term risk of wildfires, scientists say.
