The warning stretches from the Cold Lake region in the north to the U.S. border in the south, and from east of the foothills all the way to the Saskatchewan border.
Several cities are affected, including Edmonton, Red Deer, Lloydminster, Calgary, Lethbridge, and Medicine Hat.
A low-pressure system moving through the province on Wednesday will bring scattered showers and cooler temperatures, the national weather agency said.

Because of the high temperatures, residents living in areas under the heat warning are asked to take precautions like taking lots of breaks from the heat, spending time in air-conditioned buildings or in pools, drinking lots of water and not leaving any people or animals in a closed vehicle.
