Three grass fires, fanned by warm, dry winds, swept over the plains of Alberta, Canada, Wednesday.

A fire south of Nanton burned three homes along with other structures in the area, the CBC News said on its website. Residents of about 25 other houses were told that they might have to leave.

The Nanton blaze was sparked by downed power lines, as winds in the area were reportedly as high as 117 km/h, CBC said.

Another blaze had residents of about 100 southern Alberta homes on notice for possible evacuation. This grass fire burned near Granum and Fort Macleod and caused two “non-life-threatening” injuries to firefighters.

The third large grass fire blackened the plains near Walsh and the southern Saskatchewan border.

Weather data accessed by AccuWeather.com show highest winds of 75 mph (120 km/h) on Wednesday afternoon at Pincher Creek and Waterton National Park. In Claresholm, a 73-mph (117-km/h) gust was clocked.

Meanwhile, record-high temperatures for Jan. 4 were set in Calgary and at least four other Alberta cities, CBC said. Calgary’s high of 15.3 degrees C (59.5 F) topped the old mark of 12.2 C (54.0 F) set in 1914. Wednesday’s high was 30 degrees F above normal.

Other record highs were broken in Edmonton, Banff, Brooks and Medicine Hat, according to CBC.

The last two weeks have been dominated by exceptional warmth having temperatures mostly between 15 and 30 degrees F above normal.
