Environment Canada has issued a yellow smoke warning for the Ottawa region as smoke from raging forest fires in northern Quebec continues to drift south, causing poor air quality and reduced visibility on both sides of the Gatineau River. The warning is in effect until Wednesday, with forecasters also predicting high temperatures, possible thunderstorms, and gusty winds.
Smoke and Air Quality Concerns
The smoke from Quebec's wildfires prompted the yellow warning Sunday, which indicates a moderate risk to health. Ontario's Air Quality Health Index rated the smoke status in Ottawa as moderate to low risk on Sunday, dropping to low risk on Monday. However, authorities advise residents to consider reducing outdoor activities, especially vulnerable populations.
According to Environment Canada's wildfire smoke information site, individuals may experience mild symptoms such as eye, nose, and throat irritation, headaches, or a mild cough. Those most at risk include people aged 65 and older, pregnant individuals, infants and young children, people with existing illnesses or chronic health conditions, and outdoor workers.
Sunday's Forecast
Sunday started with sunny skies and a high of 28 C, with the humidex making it feel like 30 C. The UV index was rated at 8, or very high. Skies were expected to remain clear through the night, with a low of 16 C.
Monday's Outlook: Clouds and Thunderstorms
Clouds are expected to roll in on Monday, with a 30-per-cent chance of showers in the afternoon and a risk of thunderstorms. Winds could gust up to 50 km/h in the morning. The high is forecast to reach 31 C, with a humidex of 37 and a UV index of 7 (high). Skies should clear overnight, with a low near 20 C.
Tuesday: Hottest Day of the Week
Tuesday is expected to be the hottest day, with a high near 34 C and a 30-per-cent chance of showers later in the day. The combination of heat and smoke may exacerbate health risks, and residents are urged to stay hydrated and limit strenuous outdoor activities.
Precautions and Advice
Authorities recommend that residents, particularly those in sensitive groups, take precautions such as staying indoors with windows closed, using air purifiers if available, and avoiding strenuous outdoor exercise. Anyone experiencing severe symptoms such as difficulty breathing or chest pain should seek medical attention.
