LOWER LAKE, Calif. — Blazes raging in forests and woodlands across California have taken the life of a firefighter and forced hundreds of people to flee their homes as an army of firefighters continue to battle them from the air and the ground.

Twenty-three large fires, many sparked by lightning strikes, were burning across Northern California on Saturday, said state Department of Forestry and Fire Protection spokesman Daniel Berlant. Some 8,000 firefighters were attempting to subdue them.

“The conditions and fire behavior we’re seeing at 10 in the morning is typically what we’d see in late afternoon in late August and September,” said Nick Schuler, a division chief with the state Department of Forestry and Fire Protection.

“But because of the dry conditions, because of the drought-stricken vegetation accompanied by the steep terrain and winds, we’re seeing fire activity that’s abnormal for this time of year.”
