Pasting below a Special Air Quality Statement put out by Environment Canada tonight that gives more details:
---------------------------------------
[i]10:19 PM CDT Sunday 28 June 2015
Special air quality statement in effect for:
Brandon - Carberry - Treherne
Widespread smoke across Southern and Central Manitoba tonight and Monday.
A large area of smoke from forest fires in Northern Saskatchewan and the Northwest Territories has settled into the province today. In addition, another round of thicker smoke is now moving into the west central areas of the province as fires in Saskatchewan intensify. The smoke is mainly aloft and is creating hazy conditions across the entire province. However, local reductions in visibilities and air quality readings continue in areas closest to the Saskatchewan border, and may spread to other parts of the province tonight into Monday. Conditions are gradually expected to improve late Monday into Tuesday as winds shift the smoke plume westward.
