The air quality remained quite poor in Metro Vancouver and the Fraser Valley on Thursday morning because of smoke from wildfires.
However, Global News meteorologist Mark Madryga says a transition to cleaner air has begun.
Madryga said despite thinning out a little in the afternoon, widespread smoke is expected to linger on Thursday.
The Air Quality Health Index (AQHI) for many communities on the coast has already improved.
Metro Vancouver, the Fraser Valley, and a number of communities on Vancouver Island reported AQHI index readings of 10+, or “very high risk” on Wednesday.
That has dropped to below four for most communities on the island, while Metro Vancouver is seeing lower, but still mixed readings.
Madryga says the B.C. Interior will still be very smoky through the weekend because of the wildfires.
