Wisconsin<\/strong> is bracing for another round of poor air quality<\/strong> this weekend as smoke from Canadian wildfires<\/strong> drifts into the region, triggering a statewide air quality advisory<\/strong>.<\/p>\n The Air Quality Index (AQI)<\/strong> is forecast to reach levels considered Unhealthy for Sensitive Groups<\/strong>, with some areas likely experiencing Unhealthy<\/strong> conditions for everyone. The advisory is in effect from 12 a.m. Saturday through 12 p.m. Monday<\/strong> and covers all of Wisconsin<\/strong>.<\/p>\n Smoke will first move into northwestern Wisconsin<\/strong> late Friday night, spreading into the central part of the state<\/strong> by Saturday afternoon, and eventually reaching southeastern counties<\/strong> by Saturday evening. The thickest smoke<\/strong> is expected in northern Wisconsin<\/strong>, where air quality could reach Very Unhealthy levels<\/strong> for short periods, meaning health effects could be serious even for people without preexisting conditions.<\/p>\n Central and southeastern Wisconsin<\/strong> won\u2019t be spared. These areas are expected to remain in the USG to Unhealthy range<\/strong>, which means people with heart or lung disease, older adults, and children should avoid prolonged outdoor exertion. In some cases, even healthy individuals could start to feel the effects of poor air quality.<\/p>\n The southwest corner of the state<\/strong>, including communities along the Mississippi River<\/strong>, will likely see less smoke<\/strong>, with conditions hovering between Moderate and USG<\/strong>. Still, it’s a noticeable drop in air quality compared to normal summer conditions.<\/p>\n PM2.5 levels<\/strong>\u2014a key pollutant in wildfire smoke\u2014will likely decrease slightly by Sunday<\/strong>, but air quality across the state will still range from Moderate to Unhealthy<\/strong>, particularly in the north<\/strong>. Some improvement is expected as winds shift and dispersion increases, but smoke will remain a concern throughout the weekend.<\/p>\n For ongoing updates and current conditions, residents can check the Wisconsin Air Quality Monitoring<\/strong> website.<\/p>\n","protected":false},"excerpt":{"rendered":" Wisconsin is bracing for another round of poor air quality this weekend as smoke from Canadian wildfires drifts into the region, triggering a statewide air quality advisory.
