Social media users capture red, orange skies in dozen US states [Videos+Photos]

The wildfires raging in more than a dozen western United States (U.S.) states have painted the sky and polluted the air, causing disturbing scenes to unfold in front of millions of people.

In the San Francisco Bay Area, locals woke to an apocalyptic, orange-tinged sky Wednesday.

More than 90 major fires have burnt an area of land about the size of Connecticut.

“It’s after 9 a.m. and there’s still no sign of the sun,” the California Highway Patrol’s Golden Gate division tweeted, urging drivers to turn on their headlights and slow down.
