Massive smoke clouds, thick air darken Western US skies

Massive smoke clouds, thick air darken Western US skiesPeople from San Francisco to Seattle woke Wednesday to hazy clouds of smoke lingering in the air, darkening the sky to an eerie orange glow that kept street lights illuminated into midday, all thanks to dozens of wildfires throughout the West. “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. Despite the foreboding skies, there was little scent of smoke and the air quality index did not reach unhealthy levels.
