Why is the sky orange? Dozens of major wildfires have smothered California in a dense blanket of smoke, blotting out the sun, turning the sky an ominous shade of orange and coating cars in ash. A massive cloud of smoke covered much of California on Wednesday, dimming the sun to an eerie orange glow over San Francisco. The cloud can be seen on satellite imagery. About 125 miles (200 kilometers) to the northeast, winds fanned a huge wildfire in the Sierra Nevada foothills and forced authorities to order early morning evacuations and warn other residents to be ready to leave. The area is not far from the town of Paradise, where 85 people were killed by a fire two years ago, and Oroville Dam, where failing spillways forced a massive evacuation in 2017.
