Temperatures close to 30 degrees forecast as heat warning issued for Calgary

Calgarians can expect another weekend of hot weather with temperatures close to 30 C, according to Environment and Climate Change Canada.

Heat warnings were issued across much of the province on Thursday afternoon. As of 4:30 p.m., those warnings were in place for several communities, including:

• Calgary.
• Edmonton.
• St. Albert.
• Drayton Valley.
• Slave Lake.
• Westlock.

Environment and Climate Change Canada said parts of northwestern and central Alberta will see highs near 30 C in the daytime.

Unlike the so-called "heat dome" that settled over Alberta in June, which prevented the region from cooling off at night, lows are projected near 14 C.

Throughout the weekend, the warm air is forecast to spread across parts of southern and eastern Alberta. Cooler temperatures are expected starting on Monday.

"Heat warnings are issued when very high temperature or humidity conditions are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion," the weather agency said in its warning.

Environment and Climate Change Canada advised people to take the following precautions: 

• Consider rescheduling outdoor activities for cooler times of day.
• Take frequent breaks indoors.
• Drink plenty of water and other non-alcoholic, non-caffeinated beverages.
• Check for children or pets before leaving a vehicle.
• Monitor for symptoms of heat stroke or exhaustion, like high body temperature, lack of sweat, confusion or fainting. Pay particular attention to children, seniors and people with pre-existing conditions.
