Heat, air quality warnings issued for areas of central and southern Alberta

With temperatures in areas around Calgary and Medicine Hat forecast to soar into the low to mid-30s over the next couple days, Environment and Climate Change Canada has issued “yellow” heat warnings for the two cities

In Calgary, a temperature in the low-30s is forecast for Friday, spiking into the mid-30s on Saturday, before dropping back to around 20 C on Sunday

The normal daytime temperature for this time of year is around 24 C

Environment Canada says residents should consider rescheduling outdoor activities to the cooler parts of the day, take frequent breaks and drink plenty of water if you need to be outside, keep an eye on children, pets and other susceptible to the heat and monitor for symptoms of heat exhaustion, including high body temperatures, confusion and lack of consciousness

The poor air quality is expected to continue through Saturday in most areas, although Environment Canada said the visibility and air quality “can fluctuate over short distances and vary considerably from hour to hour.”

The national weather agency also issued a warning that, as smoke levels increase, people should consider reducing or rescheduling outdoor activities and keep windows and doors closed

The people most susceptible to health problems caused by wildfire smoke include those aged 65 and older, infants and young children, those who are pregnant and people with existing illnesses or chronic health conditions
