High fire risk is expected to last into January, adding to fears that 2017's deadly and destructive wildfire danger will continue. CAL FIRE reported more than 6,760 fires in California from Jan. 1 to Dec. 3. Those fires scorched more than 505,000 acres. During that same period last year, Cal Fire reported 4,742 fires that burned 244,297 acres.

The state is coming off one of its wettest winters in years, which left hillsides covered in grass and other vegetation. That grass dried out this summer and turned into tinder, providing fuel for rapidly spreading fires often pushed by strong winds.

The devastating result was an October firestorm that destroyed 5,700 homes and other businesses in Northern California and killed 42 people.

An increase in the number of dead and dying trees also can exacerbate the wildfire threat, CAL FIRE officials said. An estimated 102 million trees have died in California due to the state's five-year dry spell and bark beetle infestation.

The agency has been urging residents to take prevention steps, such as maintaining 100 feet of defensible space around homes and other structures. Defensible space provides a natural buffer between buildings and grass, trees, bushes, shrubs and other vegetation that can burn.
