Gravel, sand, and stagnant weather continue to cause dusty conditions across from the Northwest to the Cariboo.
The environment ministry has continued dust advisories for Smithers, Houston, Burns Lake, Prince George, Quesnel, and Williams Lake.
Air quality advisories are also in effect for Houston, Prince George, and Quesnel.
Those with underlying medical conditions should postpone strenuous exercise until conditions improve.
Dust levels tend to be the highest around busy roads and industry.
