Wildfires around Los Angeles have burned rapidly in the past week after vegetation growth and record heat blamed on climate change, and Southern California blazes could get worse once seasonal winds start,

Smoke was heaviest southeast of Los Angeles and widespread across the rest of Southern California. Data from air sensors suggested that the air quality was diminished in several places around the Los Angeles area. Air quality was also poor in the Northwest, including in Oregon and Idaho, where dozens more wildfires were burning.

Three rapidly growing Southern California wildfires have burned more than 100,000 acres in less than a week and continued to threaten homes in multiple communities as the state mobilized an all-hands-on-deck response to bolster front-line fire crews battling the raging flames.
