Fierce winds and bone-dry conditions are causing “firenadoes” in Northern California, with reports of flames as high as 100-feet in some parts — creating an apocalyptic scene.

“This is absolutely terrifying,” wrote one Twitter user, who posted footage of the weather phenomenon.

“It was literally a firenado barreling down on Redding,” they said. “Wildfires are getting more erratic. We can’t ignore it anymore.”

A rapidly growing wildfire, dubbed the Carr Fire, has been tearing through parts of Northern California for several days. It’s already destroyed 65 buildings and claimed the lives of two people who were battling the blaze.

“This fire is extremely dangerous and moving with no regard to what’s in its path,” Cal Fire Chief Brett Gouvea told reporters.

According to KCBS Radio, at least two fire tornadoes have been reported in the region.

Most weather experts actually refer to them as “fire vortexes” or “fire whirls” — but social media users seemed to prefer the sound of “firenado.”

“It occurs when ground level winds come into contact with a fire and whip it into the air, creating a tornado-shaped spiral of flames,” explained Cal Fire spokesperson Heather Williams.

Winds reportedly reached 60 mph on Thursday night in Shasta County, Cali., and up to 30 mph on Friday morning. The communities of Shasta and Keswick were said to have been affected, along with residents in Redding — a city of about 92,000 people.

“Firefighters continue to work aggressively to build containment lines around the Carr Fire,” officials said in a statement. “Their efforts have been hampered overnight due to extreme fire behavior and challenging wind conditions.”

Weekend forecasts call for brutally hot weather, with temperatures reaching 110 degrees on Saturday and Sunday. Evacuations have been ordered by local officials.
