Under an orange sky, vineyards and buildings were taken by the flames that spread dangerously fast over 4,500 hectares. The fires are not under control at all, according to the state fire service Cal Fire.
Several famous vineyards such as Chateau Boswell and parts of Castello di Amorosa have gone up in flames, while there is major destruction on the outskirts of the town of Santa Rosa.
Nearly 34,000 people have been ordered to evacuate, and another 14,000 have been told to get ready to evacuate quickly if necessary while the fire spreads in dry scrub and difficult hilly terrain.
Several of the sites now threatened by the Napa and Sonoma fires were reduced to ashes three years ago. Then 44 people lost their lives, and several thousand buildings burned down.
California has for several months been ravaged by forest and scrub fires that Governor Gavin Newsom says are due to climate change. They spread quickly due to prolonged drought, the strong summer wind and a heat wave.
Newsom says the fire season is now at its worst, with the strong Santa Ana wind blowing in the direction of Los Angeles. Five of the six largest fires in California’s history are now burning.
