Large swath of B.C.’s Interior under wildfire smoke advisory |

Environment Canada says many regions of B.C.’s Interior will be impacted by wildfire smoke over the next 24 to 48 hours.

Issued on Saturday, the air quality statements stretch from the Fraser Canyon in the west to the Alberta border in the east, and from Cariboo in the north to the U.S. border.

“Wildfire smoke impacts are present or expected to occur across much of the Interior and north-east,” said the national weather agency.

“Impacts are due to long-range transport from fires in Washington and Oregon as well as smoke from local wildfires.”

Environment Canada says the smoke may clear in some areas this afternoon, as an upper-level low moves through the Southern Interior, but conditions are expected to persist in most areas overnight.
