Due to a series of huge fires that broke out in about 370 sites in California, the authorities were forced to evacuate 60 thousand people, with the possibility of evacuating 100 thousand others. 

The fires, caused by "lightning" that hit the region strongly during the past four days, were concentrated in north, east and south San Francisco, and their intensity increased due to high temperatures, which contributed to the occurrence of significant pollution and a decline in air quality.
