Extreme heat, humidity to continue in the GTA on Monday: Environment Canada
Extreme heat and humidity will continue in the Greater Toronto Area (GTA) on Monday as much of the region remains under a heat warning, Environment Canada says.
Daytime highs could be between 29 to 32 C, with the humidex making it feel like it's 35 to 40 C, the federal weather agency said on Monday morning.
Overnight lows are expected to provide little relief, ranging from 19 to 23 C.
The heat warning is expected to end on Thursday night, Environment Canada says.
The warning is in effect for the following areas: Toronto, Vaughan, Richmond Hill, Markham, Mississauga, Brampton, Durham Region, Newmarket, Georgina, northern York Region, Halton Hills and Milton.
Parts of the GTA were under a severe thunderstorm watch on Sunday but that has since been lifted.
Watch for symptoms of heat stroke
Environment Canada is advising people to limit exposure to sun and heat by planning activities during the coolest parts of the day, as well as wearing a wide-brimmed hat and lightweight, light-coloured, loose fitting clothing.
People are advised to watch for symptoms of heat stroke, which is a medical emergency, in themselves and others. Symptoms can include red and hot skin, dizziness, nausea, confusion and change in consciousness.
"While you wait for medical attention, try to cool the person by moving them to a cool place, removing extra clothing, applying cold water or ice packs around the body," Environment Canada said in Monday's warning.
The weather agency also advised people to drink water often, even before feeling thirsty, and close blinds and open windows if the outside is cooler than inside.
People are advised to check in regularly on those at greater risk of heat illness, including the elderly and those living alone.
Signs of heat exhaustion may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. If you experience these symptoms, Environment Canada advises stopping your activity and drinking water.
