Los Angeles Mayor Eric Garcetti declared a state of emergency in the city Tuesday as several wildfires continued to rage across the region. Blazes in Santa Clarita, Santa Ana and Ventura County claimed tens of thousands of acres between them and filled the southern Californian skies with smoke — so much smoke in fact, they left trails visible from space.

The National Weather Service is warning of continued gusty, dry Santa Ana winds through Friday, which could help fuel more flames. One meteorologist on Twitter described the situation as a "wildfire siege." Unofficial burn map of current #Thomasfire #Creekfire and #Ryefire.

About 150,000 were affected by evacuation orders of some kind in Los Angeles, according to CNN. The Creek Fire was burning in the hills just to the north downtown LA. These fires come at the tail end of what is the worst wildfire season in California history, after fires destroyed thousands of homes and businesses and killed more than 40 people in northern California in October.
