Wildfires raise concerns about air quality in three provinces, summer storms drench Quebec and the Maritimes, and parts of the Prairies are feeling the heat. 

Here's a coast-to-coast peek at what's ahead for Thursday. 

Wild fire smoke produces low visibilities and poor air quality over Newfoundland and Labrador, Northwest Territories, and British Columbia

Environment Canada issued a special air quality statement for parts of Newfoundland and Labrador Thursday, where smoke from forest fires in the Upper Lake Melville are is creating hazy conditions.

"Smoke from several forest fires in the Upper Lake Melville area will be carried northward by south to southeasterly winds, which could cause hazy conditions over parts of the Trans Labrador Highway and the mid coast," said the agency. "This smoke could also lead to deteriorating air quality." 

People with respiratory ailments should take precaution if planning outdoor activities Thursday and Friday.

Additionally, wildfires continue to burn throughout parts of British Columbia and the Northwest Territories, where a smoke advisory remains in effect. 

"Smoke concentrations will vary widely as winds and fire behaviour change," the special air quality statement for B.C. reads. "Metro Vancouver has also issued an air quality advisory for Metro Vancouver and the Fraser Valley regional district because of high concentration of fine particulate matter, primarily due to smoke from fires in Washington." 

People with chronic underlying conditions should postpone strenuous exercise until the advisory is lifted. 

Heavy rainfall targets the Maritimes

A complex and slow moving trough of low pressure approaching Nova Scotia and New Brunswick from New England will bring scattered showers across much of the region Thursday.

"Periods of heavy rain will develop tonight and will become heavy at times on Friday," says EC in a special weather statement issued Thursday morning.

The agency says there is still some uncertainty with the system's track and intensity, "consequently determining which regions will the receive heaviest rainfall remains extremely difficult at this time." 

At this time, rainfall amounts can range anywhere from 25 to 45 mm. 

Be sure to check back for updates as warnings may be issued.

Rainfall warnings continue for parts of Quebec as a nearly stationary low brings periods of heavy rain to parts of the province.

Parts of central and eastern Quebec could see an additional 40 to 60 mm through Friday, says Environment Canada. 

Motorists are advised to use caution on the roads, as localized flooding in low-lying areas is possible.
