At least 15 people died in Sonoma County wildfires, county Sheriff Rob Giordano said at a Thursday afternoon news conference. The number of fatalities in Northern California wildfires is now at 29.

Authorities have reported two deaths in Napa County, eight in Mendocino County and four in Yuba County.

Three more people died in wildfires in Yuba County, north of San Francisco in western California, bringing the total death toll in statewide wildfires to 27, local media reported Thursday.

Sonoma County Sheriff Rob Giordano told a press conference Thursday that “the new number of death” is 14 in Somona County and that the sheriff has received a total of 900 missing people reports by Thursday morning.

He said faulty cell service hindered communication between evacuees and their families, and of the list of the 900 missing persons reports, 437 were found safe.
