A heat warning is in effect for Foothills County, the M.D. of Willow Creek and Rocky View County.
Daytime high temperatures ranging from 29 C to the mid-30s C are expected, combined with overnight lows in the high teens, according to the warning issued on July 27 by Environment Canada.
Forecast highs for Okotoks range from 28 C to 30 C through the weekend, with a high of 33 C possible on holiday Monday.
Heat warnings currently extend into northern Alberta and have also been issued across much of B.C. They are issued when very high temperatures are expected to pose a higher risk of heat stroke or heat exhaustion.
People in areas covered by this warning are encouraged to take precautions, including completing outdoor activities during cooler hours during the day, drinking plenty of water and taking breaks from the heat, and making sure children and pets are not left in vehicles for any amount of time.
Symptoms of heat stroke or heat exhaustion can include high body temperature, lack of sweat, confusion, fainting and unconsciousness.
Infants and children, seniors, individuals with pre-existing conditions or those who work outside can experience earlier or more severe effects from the hot weather. Environment Canada also recommends checking in with those who are socially isolated.
