Wildfires raging in the western US state of California have forced the evacuation of more than 20,000 people, and left one person dead, officials said.
At least 1,500 buildings were destroyed as the state declared an emergency in three counties ravaged by fires.
California's fire service said about 49,000 acres have been ravaged by the major infernos in Napa, Yonoma, and Yuba counties, which are famed for their production of wine.
More than a dozen fires are burning in total.
Forest fires are common in the western United States during dry, hot summer months, and can be further fanned by windy conditions.
Last month, a massive fire described as the biggest in the history of Los Angeles forced hundreds to evacuate their homes.
Earlier, the fires could be smelled in San Francisco, about 60 kilometers from the closest fire.
