Firefighters wrapped up Friday to control a raging hell in southeastern Oregon that stretches about 24,000 acres a day in windy conditions, one of many wildfires across the West that are straining resources.

The smoke and heat of the massive fire have been generating clouds of pyrocumulonimbus – called “clouds of fire” – which can reach up to 10 kilometers in the sky and is visible from more than 160 kilometers away.

In accordance with Oregon Live, a giant cloud of fire over the Bootleg fire collapsed Thursday night, forcing firefighters to withdraw for their own safety, said Ryan Berlin, a spokesman for the Oregon Department of Forestry.

Note the “anvil – like” shape of the pyrocumulus cloud over the Bootleg Fire.

This week meteorologists have detected larger, more extreme forms of these fire clouds creating their own unstable weather system. When this column of smoke collapses, Berlin said, it produces powerful downward currents that can throw embers through unburned parts of the landscape.

This extreme fire behavior, including the formation of more fire clouds, is expected to persist on Friday and worsen until the weekend. “It’s definitely a‘ surveillance ’situation,” Berlin said. “We pulled people off the line while they were doing what they were doing.”
