Smoke is causing or expected to cause poor air quality and reduced visibility. Smoke is causing very poor air quality and reduced visibility at times. Smoke in western Manitoba will continue clearing this evening. Smoke will be thick tonight in the Red River Valley and will move out Friday morning, while eastern Manitoba will see smokey conditions until noon Friday. People more likely to be impacted by wildfire smoke, including people aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should avoid strenuous activities outdoors and seek medical attention if experiencing symptoms. During heavy smoke conditions, everyone’s health is at risk regardless of their age or health status. Limit time outdoors. Reschedule or cancel outdoor sports, activities and events. You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance. When indoors, keep windows and doors closed as much as possible. When there is an extreme heat event occurring with poor air quality, prioritize keeping cool. Protect your indoor air from wildfire smoke. Actions can include using a clean, good quality air filter in your ventilation system and/or a certified portable air cleaner that can filter fine particles. If you must spend time outdoors, limit the time as much as possible. A well-constructed, well-fitting and properly worn respirator type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke. Even though exposure may be reduced, there can still be risks to health. Check in on others who are in your care or live nearby who may be more likely to be impacted by outdoor air pollution.
