Officials say drought conditions and shifting winds in Saskatchewan could lead to further wildfires as troops battle blazes raging across western Canada.

Steve Roberts, a Saskatchewan wildfire management official, said Thursday that the warm, dry conditions could cause more trouble in the province that already has 118 wildfires burning.

Air advisories have been issued in western and central Canada, as well as the western United States.

Officials estimate more than 10,000 people have been forced from their homes in recent days. Fires also continue to burn in British Columbia and Alberta.

Roberts says the province is seeking more firefighters and equipment from across Canada and the U.S.
