(CNN)Barely two months after fires charred Northern California's wine country, the state is once again staring down a spate of wildfires, this time in Southern California. These fires are fueled by some of the strongest Santa Ana winds in recent memory. Here are some eye-popping numbers from these latest fires:
A look at the California wildfires' jaw-dropping numbers
The Thomas Fire, the largest of the blazes, is burning through Ventura County toward Los Angeles. The blaze is more than four times the size of the Tubbs Fire (36,807 acres), which was the most destructive of the fires in Napa and Sonoma counties in October.
The Thomas Fire began Monday and moved exceptionally fast. It grew about 31,000 acres in about nine hours -- that's nearly an acre per second. That rate would burn through Manhattan's Central Park in about 14 minutes. As of Sunday morning, the fire had grown to 173,000 acres and was 15% contained.
The Thomas Fire is the biggest in Los Angeles since the Bel-Air fire in 1961 torched scores of homes of the rich and famous.
Every day, firefighters in Los Angeles receive a brush burning index report that indicates the fire danger. If it's 162 or higher, that's considered extreme. The number for Thursday was 296, a record.
The last time the Santa Ana winds were this bad -- with multiple days of warning-level winds and red flags -- was in October 2007. Wind gusts in Los Angeles and Ventura counties were expected to reach more than 60 mph Sunday. So the risk of the fires spreading remains high.
On Sunday, CalFire reported in a tweet that 98,000 residents were evacuated in Southern California.
About 6,800 homes and businesses in fire-affected areas are without power, according to Southern California Edison and San Diego Gas & Electric.
The smoke plume from the fires extends more than 1,000 miles into the Pacific, which is equivalent to the distance between New York and Miami.
This year has been the costliest for wildfires in the United States, with more than $10 billion in damages before the current Southern California fires began.
