The wildfire smoke has led to hazardous air quality levels, posing health risks to millions of residents across the U.S. Prolonged exposure to polluted air can exacerbate respiratory conditions, particularly for vulnerable groups such as children, the elderly, and individuals with pre-existing health issues. In Washington state, the wildfires have displaced tens of thousands of residents, creating immediate safety concerns and potential long-term recovery challenges. The smoke's westward movement is expected to impact air quality in Oregon and California, further expanding the affected areas.
