Officials warn again of air health in smoky Seattle

Manitoba affected by BC wildfire smoke, special air quality alert in effect

Smog, smoke prompt Spare the Air alert for Sunday

In Spokane, air quality slipped into the "hazardous" range. "These acute effects where the air quality gets worse from wildfire smoke for a few days-they probably do not have long-lasting effects in most of us".

This comes on the heels of an air quality alert that began last Thursday and was expected to dissipate by noon Sunday.

There should be "some" improvement to our air quality by late Wednesday, according to the National Weather Service.

Wildfires burning in the region and to our north combined with forecasted conditions will cause air quality to reach unhealthy and very unhealthy levels and potentially remain there until at least Tuesday evening.

The entire province of Manitoba is under somewhat hazy skies and Environment Canada has issued an air quality alert.

Take precautions: Everyone should take precautions when the air quality is unhealthy.

People active outdoors should limit their exertion.

Close windows in your home, if possible, and keep the indoor air clean.

There are 17 large fires burning on more than 300,000 acres across Washington and OR with about 8,200 fire personnel deployed, according to the Northwest Interagency Coordination Center.

On Tuesday, most parts of the state were considered moderate in terms of air quality, according to the EPA's AirNow site.

"You probably want to reduce the level of exercise you're doing outside", Dr. Sack said.

Those at particular risk include those with heart and lung conditions, as well as diabetics, infants, or the elderly.

Thick smoke is reducing visibility across much of the interior, with places like Kelowna and Kamloops reporting visibility as low as 1 km over the weekend.

Now, another index conveys just how unsafe the air quality is.
