As families prepare for the return of school this week and settle into new daily routines leading into the fall, hot and humid weather is set to return.
Environment Canada issued a heat warning Monday afternoon for most of southern Ontario. It said we can expect temperatures in the low 30s with humidex values reaching 40 to 42 C Tuesday and Wednesday.
The weather agency said the high temperatures may continue into Thursday in some regions.
By comparison, the U.S. National Weather Service is forecasting a high around 26 C in Los Angeles Tuesday.
Older adults and young children, as well as people suffering from chronic illness and those without access to air conditioning, are at greater risk of developing heat-related illness.
Environment Canada encouraged people to drink plenty of fluids, especially water, in order to prevent dehydration.
There is relief in the longer-term forecast. According to Environment Canada, we should see temperatures below 30 C starting on Friday.
