You can blame Canadian wildfires for potentially forcing you indoors until early Saturday morning. The National Weather Service issued an air quality advisory for Wisconsin on Friday that will last until 6 a.m. Saturday morning. According to the agency, air quality will gradually degrade from the north to the south as a cold front pushes wildfire smoke across the state. The state’s western counties could see the warning extended through Saturday. The air quality index (AQI) is expected to be unhealthy for sensitive groups (orange level), but potentially get elevated to an unhealthy AQI (red level). Shauna Blackledge from the Door County Public Health advises older people and those with certain health conditions to take extra precautions on such days.

According to the BBC, approximately 17,000 residents in Manitoba are under evacuation orders due to the wildfires, causing the air quality alert throughout the upper Midwest.  More than 80 fires are deemed out of control in Manitoba, forcing residents in nearby Saskatchewan to evacuate. Door County has seen air quality advisories occur due to wildfires in Canada each of the last two years.
