As a large swath of Manitoba deals with heavy wildfire smoke polluting the air, others in the province are starting the weekend amidst suffocating heat and humid conditions.
Environment and Climate Change Canada has issued an air quality warning for much of northern Manitoba including Thompson, The Pas and Flin Flon on Saturday morning.
With relatively light winds, smoke is expected to concentrate especially over the area near active wildfires, causing poor air quality and reduced visibility throughout the day.
Everyone's health is at risk, regardless of age or health status, during heavy smoke conditions, the federal agency said. But pregnant people, children, seniors and those with underlying health conditions are more likely to be impacted.
Environment Canada is advising people to reschedule or cancel outdoor sports and activities. People who work outdoors should avoid extraneous activities and seek medical attention if experiencing symptoms.
Those may include eye eye, nose and throat irritation, headaches or a mild cough. More serious.but less common symptoms include wheezing, chest pains or severe cough, Environment Canada said.
According to the province's latest fire bulletin, issued Friday, the Manitoba Wildfire Service was responding to 121 active wildfires across the province, which has seen a total of 337 wildfires to date, well above the average for this time of year of 260.
Heat warning
Meanwhile, pockets of southern Manitoba, including the cities of Winnipeg, Brandon and Portage la Prairie, are under a heat warning.
Humid and hot conditions are expected to remain throughout Saturday with temperatures reaching the low 30's C and humidex values nearing 38, Environment Canada said.
Conditions are expected to improve with a cold front moving overnight Saturday, but in the meantime the weather agency is advising people to watch for signs of early heat exhaustion including headache, dizziness and intense fatigue.
Extreme heat can affect everyone's health, but the risks are greater for older adults and other vulnerable people, Environment Canada said.
To reduce the health effects of heat, stay out of direct sunlight, drink plenty of water and stay in a cool space, closing blinds and open windows if it is cooler outside than inside or turning on air conditioning.
The weather agency also advises people to ensure children and pets are never left alone in closed vehicles.
