Officials warn residents in parts of California and Oregon to stay indoors as air quality reaches hazardous levels.

Thousands of people across California and Oregon were urged to stay inside after air quality levels spiked into the unhealthy and hazardous range. Officials say a combination of stagnant air, pollutants, and shifting weather patterns created conditions that could trigger respiratory issues, especially for children, older adults, and people with health complications. Some communities woke up to thick haze and warnings to avoid exercise, close windows, and use air filters if available. Authorities expect conditions to fluctuate in the coming days as winds and temperatures shift.
