Environment Canada has issued a Smoky Skies bulletin for Whistler and Pemberton as well as for Howe Sound.
Many regions of BC are being impacted or are likely to be impacted by wildfire smoke over the next 24-48 hours.
In the north, the Battleship Mountain fire continues to impact the Peace region with some smoke moving south and impacting the Robson Valley and Prince George.
A weather system from the south is bringing both thundershowers and smoke to the southern regions of the province. These mixed conditions mean that smoke is expected to be highly variable based on local weather, winds and terrain, the agency says.
However, clearing will begin for the south coast and for regions along the southern border into the overnight period.
During a wildfire, smoke conditions can change quickly over short distances and can vary considerably hour-by-hour. People with pre-existing health conditions, respiratory infections such as COVID-19, older adults, pregnant women and infants, children, and sensitive individuals are more likely to experience health effects from smoke exposure.
