Smoke from Canadian wildfires brings unhealthy air to large swaths of the Midwest
Air quality alerts were in effect in Iowa, Minnesota, Wisconsin and Michigan, as well as eastern Nebraska and parts of Indiana and Illinois. Forecasters said the smoky skies would remain for much of the day. People with lung disease, heart disease, children, older adults and pregnant women are most susceptible to the poor breathing conditions.
Canadian environmental officials said smoke from forest fires that was causing reduced visibility and poor quality would persist into Sunday for some areas.

The Switzerland-based air quality monitoring database IQAir, which assesses air quality in real time, listed the city of Minneapolis as having some of the worst air pollution in the world since Friday.
The Air Quality Index (AQI) is expected to reach the red or unhealthy category in a large swath of Minnesota and will likely remain through Saturday. AQI is a system used to communicate how much air pollution is in the air. It breaks pollution down into six categories and colors, and advice on what isn't safe to do. They range from 'good' (the color green) to 'hazardous' (maroon).

The smoke could start to decline beginning Saturday before spreading as far south as Tennessee and Missouri. The air could remain unhealthy for sensitive groups through Monday, state health officials said.
The EPA's Air Quality Index converts all pollutant levels into a single number. The lower the number, the better. Anything below 50 is classified as 'healthy.' Fifty to 100 is 'moderate' while 100-150 is unhealthy for 'sensitive groups.' Anything above 150 is bad for everyone. Parts of Minnesota exceeded that number on Saturday.
Health officials advise people with asthma and other lung disease, heart disease, children and older adults to avoid prolonged exposure to smoke and limit strenuous activities. They said to avoid burning things that could make the air pollution worse, and keep windows and doors closed to keep the smoke from getting inside.

Smoke from Canadian wildfires brings unhealthy air to large swaths of the Midwest
Smoke from Canadian wildfires hovered over several Midwestern states Saturday, bringing warnings of unhealthy air for at least the third day.

Environment Canada issues severe thunderstorm watches amid B.C. wildfire fight
Environment Canada has issued more than a dozen severe thunderstorm watches across British Columbia as the province continues to fight multiple wildfires. Forecasters say conditions are favourable for the development of severe thunderstorms that could produce strong winds, large hail and heavy rain. The watches cover large swaths of the Interior, including the Okanagan, the Peace River region and Prince George. Fort Nelson is under a severe thunderstorm warning, as the weather office says meteorologists are tracking a storm capable of producing up to heavy rain and hail the size of nickels.

Environment Canada lifted the heat warning that had been in place in B.C., but multiple regions are under special air quality statements due to smoke.

How to protect yourself from the bad air caused by wildfires
When wildfires burn, the smoke can travel long distances and degrade air quality far away, which presents risks for those breathing it. Fires burning in one state can make air worse several states away, and wildfires in Canada can send smoke into U.S. cities. Here's what to know about taking precautions against poor air quality due to wildfires. What counts as bad air? The EPA's Air Quality Index converts all pollutant levels into a single number. The lower the number, the better. Anything below 50 is classified as 'healthy.' Fifty to 100 is 'moderate' while 100-150 is unhealthy for 'sensitive groups,' and anything above 150 is bad for everyone. Sensitive groups include people with asthma, lung disease or chronic obstructive pulmonary disease, said Dr. Sanjay Sethi, chief of the division of pulmonary, critical care and sleep medicine at the University of Buffalo's medical school. 'If you have heart or lung problems, then you've got to be definitely more careful,' Sethi said. 'I would either avoid going outside or wear an N95 (mask) or at least a dust mask.' Is my air unhealthy? Sometimes the air is bad enough to see or smell the smoke. Even if you don't see the pollution, it can be unhealthy to breathe. The EPA maintains a website with up-to-date, regional air quality information. PurpleAir, a company that sells air quality sensors and publishes real-time air quality data, has a citizen scientist, air quality monitoring network with a more granular map of street-by-street air quality readings. The best way to get indoor air quality readings is to buy a monitor, said Joseph Allen, director of Harvard University's Healthy Buildings Program. 'You can find these low-cost, indoor air quality monitors just about everywhere online now. They don't cost all that much anymore,' he said. What if I have to go outside? For most people, going outside for just a short time won't have a negative long-term impact, said Sethi. Wearing an N95 mask, which became common during the coronavirus pandemic, will help filter out the pollution. 'N95 is going to get rid of 90-95% of the particles,' said Jennifer Stowell, a research scientist at Boston University's Center for Climate and Health. 'If you have access to a mask that has a respirator-type attachment to it, then that's the very best.' If you must be outside and you experience symptoms, experts say you should head indoors or somewhere else with better air quality. Even if you are healthy, it's good to take precautions. 'If you start wheezing, which is like this whistling sound of the chest, or if you're feeling short of breath, that's definitely more concerning,' Sethi said. How do I make my air cleaner? Close the windows and turn on the air conditioner, if you have one, setting it to circulate the indoor air. Use blankets to cover cracks that allow outside air into your home, such as under doors. Finally, swapping the air conditioner's filter for a MERV 13 filter can help, though you should make sure it's installed correctly. 'If you happen to have access to an air purifier, even if it's just a room air purifier, try to keep it running and in the room that you're doing most of your activities in,' said Stowell. ___ The Associated Press' climate and environmental coverage receives financial support from multiple private foundations.
