Heat warning in effect in Hamilton, surrounding areas could feel like 39
Monday is set to be the hottest in Hamilton with a high of 31 C, but it may feel more like 39 with the humidity factored in.
"There is some uncertainty in the duration of the heat event for some regions ... Over some areas the heat event could persist into Wednesday," the weather agency said in its heat warning.
Tuesday is expected to see a high of 31 C and a low of 20 C.
Environment Canada recommends people check on those who are vulnerable, stay hydrated and watch out for symptoms of heat exhaustion.
"Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue," said the weather agency.
It also suggests people close their blinds and open windows if it feels cooler outside than inside.
Using a fan or air conditioner, limiting direct exposure to the sun, and wearing lightweight, light-coloured clothing also advised.
The medical officer of health for the City of Hamilton initiated a heat warning starting Sunday.
The city and some community agencies will open cooling areas for people to go to during the heat and humidity.

Ottawa Hospital satellite clinic tends to Ironman athletes
Those at an Ottawa Hospital satellite clinic worked hard Sunday to take pressure off hospital emergency rooms across the city as thousands of Ironman athletes pushed themselves to the limit.

Article content Article content Six medical teams and 300 volunteers staffed the facility through the day, providing treatment for dehydration, injuries and heat-related issues. There were also teams scattered across the Ironman course to provide on-site medical services.

Article content Jackie Mace, captain of the main medical tent, said the clinic was a fully-equipped intensive care unit with cardiac monitors, AEDs, cardiac medication and equipment to intubate patients. Article content The goal was to divert patients from going to the hospital, she said. Usually, around 10 per cent of race participants will come into the tent for medical attention. Article content Article content 'The patient will come in really, really sick, but the minute that you get their core temperatures down to a much more normal level, they rebound really quickly. Article content 'They can come in looking like terrible near death, and an hour or two later, they're having conversation with you and are ready to go home. So that's why, this way, we avoid having all these patients from going to the hospital.' Article content Article content For the past decade, The Ottawa Hospital has led medical tent and on-course medical services for Ottawa Race Weekend.
