Northern California’s catastrophic wildfires have killed at least 31 people, a toll that surpasses the single deadliest fire in the state’s history. In 1933, the Griffith Park fire killed 29 people, according to officials.

Officials said Thursday that 21 major fires were still burning across the state.

Since igniting on Sunday, they’ve swept across roughly 300 square miles. In Santa Rosa alone, an estimated 2,834 homes were destroyed, the city’s mayor said on Thursday.

Canine teams have now began the grim task of looking for bodies in the wreckage. “It’s going to be a slow process,” said Robert Giordano, the Sonoma County sheriff.

With gusty winds expected Friday night and into Saturday, exhausted firefighters were bracing for yet another day of battle.
