An Air Quality Advisory and Open Burning Restrictions have been re-issued for of Smithers and Telkwa.
Air Quality Meteorologist, Barry Watson says this is because of particulate emissions that are being trapped at the surface due to the strong weather and terrain inversion in the area.
“A significant change in weather should improve conditions,” he says. “But the last week we’ve had that high pressure system and very strong inversions and basically pollution emissions have accumulated from day to day and there aren’t winds blowing that away.”
Watson says people who are sensitive to poor air quality should remain indoors.
The advisory for Burns Lake and Houston also remains in effect.
He says warm air aloft is trapping particulate emissions at the surface due to weather and terrain inversion conditions.
