The Thomas Fire grew over the weekend and is now among California's largest wildfires in history
The Thomas Fire began Tuesday and quickly grew to more than 90,000 acres. It grew over the weekend and is now among the largest fires in California's history.
How does the number of acres burned in Ventura County compare it to other blazes up and down the Golden State?
Thomas Fire
The Thomas Fire started about 6:30 p.m. Dec. 4 near highways 150 and 126, north of Santa Paula in Ventura County. As of Monday morning, it burned 230,500 acres and destroyed nearly 800 buildings.
Strong Santa Ana winds were blamed for pushing flames within a short amount of time and firefighters feared they would make it difficult to put out the blaze.
In Southern California, winds usually blow from west to east, which cools the region with moist air from the Pacific. It is why Angelenos can brag about their great weather.
Santa Ana winds, though, blow east to west from the desert, usually in the fall, causing hot and dry conditions along the coast. They can generate hurricane force winds that whip through Southern California cities, causing problems from fallen tree limbs to wildfires.
As of Monday, firefighters had contained 15 percent of the fire. There was no estimation on when the fire would be under control.
