METRO Vancouver is continuing the fine particulate matter advisory that has been in effect since September 8 for Metro Vancouver and the Fraser Valley Regional District due to wildfire smoke from outside the region. Wildfire smoke from fires in Washington and Oregon continues to persist in the region.

Air quality has continued to improve since Tuesday but ground-level smoke still remains and is expected to remain through the week. A weather system forecast for Friday is expected to bring further improvements this weekend. Localized smoke concentrations may vary widely across the region as winds and temperatures change, and as wildfire behaviour changes.

In the city of New Westminster, a timber wharf at Westminster Pier Park continues to burn producing local smoke. For New Westminster and surrounding areas, follow the advice provided by Fraser Health:
