The regional district is continuing its fine particulate matter advisory that has been in effect since Sept. 8 for Metro Vancouver and the Fraser Valley Regional District due to wildfire smoke from outside the region.
The forecast indicates slight improvement in air quality today but ground-level smoke will remain, and possibly until later this week, Metro notes.
Localized smoke concentrations may vary widely across the region as winds and temperatures change, and as wildfire behaviour changes.
The region is also reminding people that those with chronic underlying medical conditions or acute infections, such as COVID-19, should postpone or reduce outdoor physical activity until the advisory is lifted, especially if breathing feels uncomfortable.
