Firefighters are facing dry and windy conditions as they battle California’s deadliest wildfires that authorities say have killed at least 35 people, left hundreds missing and devastated entire neighborhoods in California.
Intensified by strong winds and low humidity, the 17 wildfires have charred more than 221,754 acres of land, forced more than 20,000 residents to evacuate and damaged or destroyed at least 5,700 homes and other structures, according to the California Department of Forestry and Fire Protection.
The decreased number of blazes from 21 Thursday reflects the merging of several fires while three have been completely contained.
Santa Rosa, a city in Sonoma County known for its wineries, was among the hardest hit areas, with at least 2,834 homes destroyed. Critical infrastructure was also lost in the flames, including the city’s fire station, Santa Rosa Mayor Chris Coursey said at a news conference Thursday afternoon.
A total of 3,900 people are being housed in 43 shelters, said Mark Ghilarducci, director of California Governor’s Office of Emergency Services.
The cause of the fires is still under investigation. But, officials believe that significant progress has been made in the last 24 hours.
More than half the deaths from the fires occurred in Sonoma County alone, authorities said. Taken together, the death toll exceeds the number of fatalities in the 1933 Griffith Park Fire in Los Angeles, the deadliest wildfire in California’s history, killing 29.
Authorities said an alert system put in place gave residents ample time to evacuate and likely prevented many deaths.
“We have a subscription service where we can alert our residents, and we did that right away, trying to notify everybody where the fire was, where it was going and how fast it was going, and I think it saved a lot of lives,” Sonoma County Sheriff’s Sgt. Spencer Crum told ABC News in an interview Tuesday.
About 250 people, most of whom are elderly, were unaccounted for in Sonoma County as of Thursday night, according to the sheriff’s office. Out of 1,308 missing person reports that have been filed since the fires began, about 1,052 people have been safely located. The sheriff’s office said some of the reports may be duplicates.
With mandatory evacuation orders and road closures still underway, many residents in the affected areas have been warned not to return to their homes until further notice.
California Gov. Jerry Brown has declared states of emergency for Napa, Sonoma and Yuba counties in Northern California.
“Life is more important than property,” Sonoma County Sheriff Robert Giordano said at a news conference Tuesday.
Another round of gusty winds and dry air
While overall containment of the flames has increased, a large weather system moving into the region Friday will bring another round of gusty winds and low humidity to the state over the weekend. Gusts could reach up to 60 mph in some areas late Friday night into Saturday morning, while daytime humidity could be as low as 10 percent.
The combination of strong winds, dry air and warm temperatures will create “critical fire weather conditions” and “contribute to extreme fire behavior,” the National Weather Service warned.
Red flag warnings for gusty winds and low humidity remain in effect across the fire areas in much of northern California and parts of Southern California. The conditions will challenge the more than 9,000 firefighters working to snuff out the flames and prevent new wildfires from igniting.
With firefighters stretched thin throughout the state, hundreds of additional fire engines and personnel have been requested from other states to help relieve crews on the front lines and be prepared for the possibility of more blazes, according to the California Department of Forestry and Fire Protection.
Most of the flames ignited on the night of Oct. 8 or during the early morning hours of Oct. 9.
