Western wildfires cause widespread air quality issues
Smoke from wildfires in the western United States is causing significant air quality issues across several regions. Originating primarily from large fires in California and Oregon, exacerbated by dry conditions and high temperatures, the smoke is being carried eastward by prevailing winds. This has led to hazy skies and reduced visibility in areas far from the fires, with air quality indices reaching unhealthy levels.
