“We’ll get more of a flow off the ocean, from the west, rather than the south — that will clear things up,” said Madryga.

Metro Vancouver also renewed its 10-day-old advisory for the regional district and the Fraser Valley.

The index projects air quality in all regions of the province should improve to “moderate” or “low” risk by Saturday.
