Smoke from B.C. wildfires delays Kamloops flights, prompts warning in Metro

VANCOUVER — Smoke from numerous wildfires burning in British Columbia's Interior prompted the Kamloops airport to cancel several flights Tuesday because of poor visibility.

Air quality around Kamloops is forecast to reach a rating of eight out of ten-plus, meaning smoke-laden air poses a high health risk for infants, the elderly and those with lung or heart conditions.

The smoke is also smudging the skies of Metro Vancouver, resulting an air quality advisory for the area and for the Fraser Valley due to high levels of fine particulates.

In Quesnel and the North Okanagan, the air quality carries a high health risk rating, with a rating of seven.

Williams Lake in the central Cariboo, where thousands were forced from their homes on the weekend, is listed at a very high health risk, with a ranking of 20, although conditions are expected to improve through the day.

An Environment Canada special air quality statement remains up for all areas but the northern and coastal regions of B.C., with a warning that concentrations of smoke particles will vary widely as winds, fire behaviour and temperatures change.
