Wildfire smoke deteriorates air quality in Ottawa

Wildfire smoke is blanketing Ottawa as a heat wave continues, prompting some residents to stay indoors. CTV’s Kimberley Johnson reports.

Wildfire smoke from the Prairies is causing some hazy conditions in Ottawa as a heat warning for the nation’s capital continues.

The forecast for Ottawa calls for widespread smoke with an air quality health index (AQHI) in the high-risk category. At 1 p.m., the AQHI was 8.

The air quality improved later in the afternoon but was still in the moderate risk category. As of 4 p.m., the AQHI was 5.

The forecast high is 31 C with a humidex of 39. The UV index is 9, or very high.

A special air quality statement was issued for Ottawa late Monday morning.

“Smoke is causing or expected to cause poor air quality and reduced visibility,” the statement says.

“As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events.”

Smoke from wildfires in western Canada is blowing across Ontario, according to firesmoke.ca.

The heat warning that has been in place since the weekend is expected to end later this week, Environment Canada says.

“A shift in the weather pattern late this week will likely end this multi-day period of heat and humidity Thursday night,” the warning states.

Monday night’s forecast is clear, but hazy, with a low of 19 and an AQHI of 5, or moderate risk.

Tuesday’s outlook is sunny with a few clouds and haze moving in by the afternoon. The forecast high is 33 C with a humidex of 41, a UV index of 9 and an AQHI of 5.

Wednesday is looking cloudy with a high of 33 C.

Air quality statement for eastern Ontario, western Quebec

An air quality statement is also in effect for eastern Ontario and western Quebec.

“Smoke from forest fires over northern Ontario has moved into the area, causing the air quality to deteriorate. The poor air quality may persist through the day and possibly into Tuesday for some areas,” Environment Canada says.

The statement stretches across much of Ontario and north into western Quebec.

Environment Canada says people might experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough because of the smoke.

“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,” the statement says.
