WINNIPEG — Air quality warnings are in effect for Manitoba as wildfire smoke continues to blanket much of the province.

Environment Canada says Winnipeg and the city of Flin Flon in the province’s northwest are expected to see air quality health index ratings of over 10.

The agency also says Brandon, in western Manitoba, is expected to see high risk conditions.

The warnings come as the province is dealing with 136 active wildfires, with 19 considered out of control.

Wildfire smoke is also lingering over northwestern Ontario, with an air quality warning for Thunder Bay and a forecast for moderately risky conditions heading into Saturday.

Environment Canada says the smoke is expected to cause reduced visibility and people are advised to limit their time outdoors.
