The amount of fine particulates in the air in Grand Portage is low this morning. I smelled smoke at my house near Colville on Saturday morning, but the rain quickly cleaned up the air. The fires are still burning in Canada, so keep checking the air quality at the Grand Portage hazecamera, especially for children elders, and those with respiratory or cardiovascular conditions. High amounts of particulates can exacerbate heart and lung disease.
If you smell smoke and/or see haze from smoke, it is likely the particulates are high, so stay indoors and run your air conditioner if you have one. If you think the particulates are high, avoid physical activity outside.
