Heat warnings are in effect across southern and east-central Alberta as dangerously hot conditions settle in across the province.
Environment and Climate Change Canada issued the alerts Thursday morning, noting that very high temperatures pose an elevated risk of heat illness, including heatstroke and heat exhaustion. In east-central and southwestern Alberta, daytime highs are expected to reach 30°C or higher over the next three days. In the far southeast, conditions are far more severe: daytime temperatures are forecast between 34 and 38°C, with the heatwave expected to continue for most of next week.
Edmonton extended its extreme heat response through Sunday, having activated it Wednesday when forecasts showed three consecutive days at 29°C or higher. As part of its response, the city installed 29 potable water stations attached to fire hydrants to help vulnerable residents. Calgary residents should monitor local conditions and take precautions in the heat — stay hydrated, check on vulnerable neighbours, and limit strenuous activity during peak afternoon hours.
