Fire Tornadoes, Fire Clouds, Crown Fires
USA Today explains Fire Tornadoes, Fire Clouds, Crown Fires
Fire Tornadoes and Whirls
Fire tornadoes are generated when intense heat from a wildfire causes hot air to rush up from the ground. As air comes in it sometimes starts to rotate. The Great Chicago Fire in 1871, one of the most devastating in American history, was exacerbated by fire whirls.
Running fires are when fires accelerate at a rate faster that can be controlled. Crown fires take place when fires climb a tree; they usually spread below the tree line before making their way upward.
“You can almost watch tree to tree burn in a matter of seconds from each other and you’ll see this gigantic flame wall spreading on the tops of trees,” said Heath Hockenberry, the National Weather Service's national fire weather program manager.
Pyrocumulus Fire Clouds
Pyrocumulus clouds – essentially “fire clouds” form over heat sources. The bushfires that ravaged Australia earlier this year featured the massive clouds. “They’re very concerning for firefighters because they cause their own storm,” said Hockenberry.

119,000 Evacuees and 900,000 Acres Torched
The New York Times reports 119,000 Evacuees as Blazes Spread.
Firefighters are struggling to get a handle on the 560 wildfires that are spreading rapidly throughout California, torching more than 900,000 acres of land and forcing more than 119,000 people to flee their homes.
Despite the 12,000 firefighters currently battling the blazes, about a dozen major fires continue to grow, particularly in Northern California, where two fire groupings are now some of the largest in the state’s history.
Even as the fires grow further, forecasters with the National Weather Service’s Bay Area office warned that there could be more dry thunderstorms this weekend, potentially bringing a dangerous combination of lightning and wind to an already-burning region. Many of the current fires were ignited during an extraordinary period of more than 12,000 lightning strikes last weekend, what fire officials have called a “lightning siege.” They have now burned a size of land larger than Rhode Island.
Entire University of California, Santa Cruz Campus
The C.Z.U. Lightning Complex has led fire officials to order 77,000 people in San Mateo and Santa Cruz Counties to evacuate, including the entire University of California, Santa Cruz, campus. That group of fires has grown to 63,000 acres, consumed almost 100 buildings and is 5 percent contained.
